V-Slam Impactor VSI
# V-Slam™ Vertical Shaft Impactor
V-Slam™ VSI Models from Stedman are vertical shaft impactors for all your coarse-to-fine crushing needs. VSI crushers offer significant savings over higher-priced competitive crushers. The V-Slam, with its low horsepower per ton of throughput, minimizes operating costs.
Our vertical shaft impactors feature multiple rotor configurations for various [applications](https://www.stedman-machine.com/industries-served.html). From open and enclosed rotors to the Stedman Patented Tubular Rotor, each machine is configured to provide customers with exactly what is needed for their unique application.
The V-Slam has a wide speed range as well as the highest rotor tip speed allowing a high degree of process control.
The new Patented Tubular Rotor provides many benefits over the standard shoe and anvil designs as well as rock-shelf applications. The easily replaceable and indexable rotor tubes, cut your total operating cost and maintenance time in half, making V-Slam the easiest VSI crusher to maintain and one of the best **[impact crushers](https://www.stedman-machine.com/impact-crushers.html)** on the market.

Size Reduction Equipment
# Size Reduction Equipment
**"Adding energy to a material to make large pieces smaller"**
**Energy + Material = Size Reduction**
Different types of particle size reduction equipment are available and each has its own method of reduction. The right size reduction machine for the task is the one that can add energy most efficiently for the application.
[Request A Quote](https://www.stedman-machine.com/rfq.html)
## What is Size Reduction?
##### Size Reduction = Material + Energy
Stedman Machine Company uses the size reduction expertise to help evaluate, test, and specify the best size reduction equipment for your application driven project. Stedman Machine uses different styles of crushers, grinders, cage & chain mills based on the raw material being processed.
## What are the types of Size Reduction Equipment?
- Impact – hitting friable material causing fractures
- Shear – tearing or ripping
- Compression – breaking material by squeezing
- Attrition – material pieces colliding with each other causing reduction
### How do I know what Type of Size reduction Machine I Need?
Crushers are often described as Primary, Secondary, Tertiary, etc. depending on how many size reduction steps are needed and where within the process each reside. There are many types of equipment choices but selecting one depends on the answers to the following questions:
- What is the material?
- What is the moisture content?
- What is the maximum size going into the machine?
- What is the size ranged desired after crushing?
- What is the desired production rate of finished product?

### Size Reduction Machine FAQs
[What should you consider when designing a size reduction system?](https://www.stedman-machine.com/#collapse-What-should-you-consider-when-designing-a-size-reduction-system-1)
As you look for particle size reduction equipment, if you have the answers to the following basic questions, a good, experienced supplier can help you maneuver through designing the best equipment for your application. Begin by answering these five questions:
- What raw material will be crushed?
- What's the raw material's moisture content range?
- What's the raw material's particle size range?
- What production rate should the size reduction equipment achieve (in pounds per hour, tons per hour, or kilograms per hour)?
- What particle size range must the final product have?
[What type of equipment is best for frequent material changeover?](https://www.stedman-machine.com/#collapse-What-type-of-equipment-is-best-for-frequent-material-changeover-2)
For processes that require frequent changeovers, particle size reduction machines with a wide range of process control and operating flexibility are the answer. Whether the materials are friable or not will affect the type of particle size reduction equipment that’s optimal. In addition to material type, the starting and final size of the milled material drives the mill selection process. **[Contact the experts](https://www.stedman-machine.com/contact-us.html)** at Stedman Machine Company to discuss which size reduction machine is best for your application.

### Secondary Impact Crusher Production
The feed enters the primary crushing chamber and meets the breaker bars which impel the feed against the front breaker plate. This action and the collision of material against new feed results in impact reduction. Material is sufficiently reduced in the primary chamber and passed by the front breaker plate, entering the secondary chamber for final reduction. Breaker plates are shaft suspended at the front and from a spindle in the rear, allowing for continuous gap adjustment as wear progresses and assuring superior product control.
This [stone](https://www.stedman-machine.com/aggregate-crushing.html) crushing machine has a multi-turn breaker bar for extended life before change out and provides years of dependable service. The features of the Grand-Slam deliver unmatched throughput of any competitive machine on the market, making the Grand-Slam HSI highly economical.

Hammer Mill Crushers
# Hammer Mill Crushers
### What is a Hammer Mill Crusher?
A hammer mill is a [rock crusher](https://www.stedman-machine.com/aggregate-crushing.html) that employs a rain of hammer blows to shatter and disintegrate a variety of materials. Hammer mills produce a finished product size that is dependent upon the following criteria:
1. Openings in perforated screens or grate bars
2. Number, size, and type of hammers
3. Grinding plate setting
4. Rotor speed
### Types of Hammer Mill Crushers

### Testimonials
**Robinson Brick Reduces Grinding Downtime and Increase Efficiency**
Robinson Brick is known throughout the industry for trying new and innovative things with their equipment. In 1998, it became the first facing brick manufacturer in North America to be registered under the ISO 9001 standard. It continually upgrades its production operation, paying careful attention to quality. When their [hammer mill crushers](https://www.stedman-machine.com/hammer-mill-crushers.html) were taking too much downtime to fix, they turned to Stedman Machine. Not only was Robinson satisfied with the machines, they were pleased with the quality of service provided by Stedman.
> Whenever we need assistance, Stedman has been right there. The Stedman guys know what they are doing and we can get a hold of them during off hours and on the weekend. We are very pleased with the Stedman impactor. It was the right choice. It has eliminated grinding downtime in a big way.Tony Fabrizio, Robinson Brick Director of Manufacturing and R&D

Impact Crushers
# Impact Crushers
#### What is an Impact Crusher?
An impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Impact crushers are designated as a primary, secondary or tertiary rotor crusher depending on which processing stage the equipment is being utilized.
### Types of Impact Crushers:
- Horizontal shaft impactors (HSI): [**M** **ega Slam Primary Impact Crusher**](https://www.stedman-machine.com/mega-slam-impactors.html) & **[Grand Slam Secondary Impact Crusher](https://www.stedman-machine.com/grand-slam-impactors.html)**
- **[Cage mill pulverizers](https://www.stedman-machine.com/cage-mill-pulverizers.html)**
- **[Vertical shaft impactors](https://www.stedman-machine.com/v-slam-impactors.html)** (VSI)
- **[Asphalt Recycling Crusher](https://www.stedman-machine.com/grand-slam-asphalt-recycler.html)**

### Rock Crusher Manufacturer
As a trusted aggregates crusher manufacturer, every Stedman crusher is engineered for a maximum feed size, target output size, and total capacity, but selecting a crusher on these criteria alone is merely half the task. These can be used as a [aggregate crusher](https://www.stedman-machine.com/aggregate-crushing.html), [mineral crusher](https://www.stedman-machine.com/aggregate-crushing.html), [asphalt crusher](https://www.stedman-machine.com/grand-slam-asphalt-recycler.html) and many more. Every size reduction project requires evaluation of the complete process to maximize production and keep operating costs low. From start to finish Stedman provides you with the information to make the correct choices for your processing needs.
### Features & Benefits
- Primary, secondary and tertiary impactors available
- Industry-leading rotor designs
- Easy [maintenance](https://www.stedman-machine.com/maintenance.html)
- Front and rear opening housings on HSI Impactors
### How does an impact crusher work?
Feed enters the crushing chamber and meets the breaker bars or plates propelling feed against the breaker plates resulting in impact reduction. There are no screens or grates holding material inside impact crushers, so material is efficiently processed at high rates for low costs.

[Have Questions? Ask Our Experts](https://www.stedman-machine.com/contact-us.html)
### How can I tell if my material can be crushed with an impactor?
Before this question can be addressed, we need to first determine if the material is friable. When we're talking about dry material processing, friable means a material will break before it bends. Thousands of materials are successfully crushed with impactors using many different equipment variations.
There are also many friable [materials](https://www.stedman-machine.com/industries-served.html) that aren't well suited to impact crush. Granite, for example, is friable but too hard, making impact crushing more expensive than other types of crushing. Stedman Machine has extensive experience crushing a variety of materials, a testing facility with full-sized equipment, and more than 10,000 test reports to help you determine what type of equipment is best for your needs.
[Contact](https://www.stedman-machine.com/contact-us.html) our experts today to discuss your specific application!

### Supplying the product you need
Grinding corn, rye, wheat and malted barley for distilleries calls for the right equipment. Grain must not be overheated in the grinding process because it could affect the flavor of the final product. The ground grain must be uniform, and have a consistent particle size.
Stedman Machine’s [**Copper Line** **Cage Mill**](https://www.stedman-machine.com/copper-line-cage-mill.html) delivers the proper power, precision and performance you need for large-scale processing of grain and corn without altering the essential taste and flavor of the product.
### Distillery Case Studies
So what has changed with whiskey distilling over time? In a word efficiency. The steps to convert raw grains into the myriad of beverages millions enjoy today remain largely the same. However, the processes have been refined or streamlined and are now considerably more efficient. Stedman Machine has integrated into the distillery process to improve efficiency.

Asphalt Recycling
# Asphalt Impact Crushers
**Highest First Pass Yield**
Crushing oversized recycled asphalt pavement (RAP) efficiently is key for reintroducing in-line material screened from the top deck back into the hot mix.
[Stedman asphalt recycler](https://www.stedman-machine.com/grand-slam-asphalt-recycler.html) makes short work of crushing RAP. The HSI, asphalt crusher, specifically engineered for the asphalt industry, reduces RAP to the required size quickly and easily for further processing. Stedman streamlined the design of its proven Grand Slam™ HSI to allow for a lighter footprint of the asphalt recycler while maintaining the necessary featuers of the HSI Grand Slam.
Contact us for typical output gradations.
[Request a Quote](https://www.stedman-machine.com/rfq.html)
## How Asphalt Crushing Equipment Works
As material loads in the [Grand Slam asphalt impact crusher](https://www.stedman-machine.com/grand-slam-asphalt-recycler.html), the low-torque rotor and breaker bars throw material against single-apron wear plates. Additionally, the material hits against itself breaking along the natural fissures in the RAP. Once properly sized, the material passes through the pre-designated gap between the rotor and apron.
### Asphalt Crusher Features
- Minimal daily maintenance for high uptime
- Auto-lube option reduces daily maintenance labor costs
- Unitized liner package for quicker replacement
- Industry leading HSI rotor design
- Simplified apron adjustment system
- Reduced machine footprint

Cage Mills & Pulverizers
# Cage Mill Crushers & Pulverizers
#### What does a Cage Mill do?
Cage mills are mechanical impact machines that crush, grind, or pulverize a variety of materials to specified degrees of fineness. They can be configured in two, four, and six row designs depending on the specific application needs, and are commonly used to pulverize industrial materials including [coal](https://www.stedman-machine.com/mineral-crushing.html) and [agricultural limestone](https://www.stedman-machine.com/aggregate-crushing.html).
### Types of Pulverizers/ Cage Mills:
- Multi-Row Cage Mills
- Single Row Cage Mills (Secondary Crusher)
- [H-Series Impact Mill](https://www.stedman-machine.com/h-series-impact-mills.html)
- [Copper Line Cage Mill](https://www.stedman-machine.com/copper-line-cage-mill.html)

### Stedman Machine Cage Mills
Stedman’s range of multi-cage mills and pulverizers includes the **[H-Series](https://www.stedman-machine.com/h-series-impact-mills.html)**, [**F-Series**](https://www.stedman-machine.com/f-series-cage-mills.html) for sticky, high moisture and **[Y-Series](https://www.stedman-machine.com/y-series-cage-mills.html)** designed for less abrasive material applications. In general, the larger the pulverizer, the larger the feed size it will accept and the greater capacity it will produce. Capacity also depends on upon the speed at which the mill is operated, the feed size and its specific gravity, and the size of the desired product. Cage mills work by reducing the material they are fed to predetermined smaller sizes by striking repeatedly with cage pins and throwing the particles at high speed against each other, against the cage mill housing and against the other pins.
### Industrial Pulverizing Equipment Features & Benefits
- Up to 40:1 Reduction Ratio
- 2 to 7 Hp per ton
- Tertiary crusher: for fine material
- Wet & sticky material is NOT a problem
### What is a Single Row Cage Mill?
Single-row mills, although normally classified as secondary crushers, are designed for heavy-duty crushing, frequently of hard and highly abrasive materials, although their versatility makes them valuable for the reduction of many kinds of [materials](https://www.stedman-machine.com/industries-served.html). They are particularly useful in the beneficiation of sand and gravel and in the upgrading and crushing of all kinds of [aggregates](https://www.stedman-machine.com/aggregate-crushing.html), [ores](https://www.stedman-machine.com/mineral-crushing.html) and coal.
[Have Questions? Ask Our Experts](https://www.stedman-machine.com/contact-us.html)
### What is a Multi-Row Cage Mill?
Multi-row mills normally consist of an even number of cages: two, four or [six](https://www.stedman-machine.com/six-row-cage-mill.html). The cages are arranged concentrically, with each cage spinning in the opposite direction from that of the cage adjacent to it. A multi-row cage mill employs multiple stages of selective impact reduction. The material to be reduced is fed into the center of the innermost cage, where it is struck by the massive spinning pins and distributed 360 degrees around the cage. Centrifugal force and the impact of the pins causes the material, now reduced to smaller pieces, to pass through the cage into the pins of the next cage, which is spinning in the opposite direction. The farther away from the center cage the particles travel, the more their impact velocity is increased.

Lump Breakers
# Lump Breakers
### What is a Lump Breaker?
Lump breaker machines, also referred to as lump crushing equipment, are size reduction machines that crush materials with their state-of-the-art blades. Lump crushing equipment is able to reduce lumps created in the production, storage or transportation of bulk solids and powders - without generating excessive dust and fines. The rotation of specially shaped blades through a fixed comb gives an efficient lump breaking action for industries such as food processing, pharmaceutical, & [mining](https://www.stedman-machine.com/mineral-crushing.html).

Full Circle Hammer Mill
# Full Circle Hammer Mill
Stedman designs, develops, and delivers high-performing, long-lasting full circle hammer mills, also known as an air swept mill, that provide a finer grind than standard hammer mills.

### What is a Full Circle Hammer Mill?
The Stedman Full Circle Hammer Mill is a fully reversible air-swept mill that targets a finer end product while increasing production capacity. It is perfect for a wide variety of industries where materials must be ground into a smaller particle size than a standard hammer mill. Our standard hammer mill uses a rain of hammer blows to shatter, crush and disintegrate materials, usually rocks and minerals, upon impact. The size of the finished product depends on the openings in screens or grates; the number, size, and type of hammers; the grinding plate setting; and the rotor speed.
Our full-circle hammer mill incorporates a turbulence channel at the bottom of the rotor which interrupts the material flow before returning it to the path of the hammers. This unique of the air swept mills design delivers a finished product with much smaller – usually medium to fine – particle size.
Stedman’s full-circle hammer mill is perfect for a wide variety of **[industries](https://www.stedman-machine.com/industries-served.html)** where materials must be ground into a smaller particle size than a standard hammer mill.

H-Series Impact Mill
# H-Series™ Cage Mill
The Stedman H-Series multi-cage mill is best at pulverizing, grinding, crushing and mixing abrasive and non-abrasive materials – wet, sticky or dry. H-Series Models work more efficiently than other types of **[pulverizer machines](https://www.stedman-machine.com/cage-mill-pulverizers.html)** and provides a finer, more uniform grind.
H-Series impact mills can handle up to 180 tons per hour and are reversible for extended wear life. The H-Series cage mill is engineered and constructed to operate at or near-peak efficiency longer, providing a greater return on capital investment over its life than competing equipment.
Each H-Series Impact Mill housing can accommodate two-, four-, or six-row cage assemblies. This versatility is further enhanced by the capability to vary the number of pins in each row, to vary the rotational speed of each cage in relation to the other(s), and to change the relative direction of rotation of the cages.

### How to Choose The Right Aggregate Crushing Equipment
Primary crushers are first in a typical size reduction operation. Primaries like our **[Mega-Slam™](https://www.stedman-machine.com/mega-slam-impactors.html)** horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes. The **[Grand-Slam™](https://www.stedman-machine.com/grand-slam-impactors.html)** HSI is well suited as secondary crusher for aggregate production for a wide range of materials including limestone, frac sand, gravel, stone, and more. Tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. This stage of crushing is typically accomplished using a [**vertical** **shaft impactor**](https://www.stedman-machine.com/v-slam-impactors.html) as an aggregate pulverizeror coarse, medium-fine, or fine grinding **[cage mill](https://www.stedman-machine.com/cage-mill-pulverizers.html).**
[Have Questions? Ask Our Experts](https://www.stedman-machine.com/contact-us.html)
Limestone, sand, and gravel are used for building and public works projects. These materials are key ingredients in cement and [asphalt](https://www.stedman-machine.com/asphalt.html) for the construction of roads, buildings, and bridges.
Specialty uses of limestone include the manufacturing of pharmaceuticals, toothpaste, paint, paper, caulking, and glass. Flooring materials, carpets, and plastics all contain finely ground recycled limestone. Common antacids are virtually 100% finely ground limestone. Farmers can reuse limestone to neutralize acidity in their soils, saving money by reducing fertilizer use while improving crop yields.
Our field-proven rock and aggregate crushing equipment will give you years of dependable and profitable service. Innovative features make Stedman machines superior in performance.

### Aggregate Crushing Equipment Case Studies
**Cage Mill Meets Most Aglime Specifications in One Pass**
The 4-Row Cage Mill allows Aglime producers to meet most state Aglime specifications in an open circuit. It will economically produce Aglime to any specification for both large and small producers. The 4-Row Cage Mill feed does not have to be dry. Clogging, jamming and plugging are eliminated with aggregate pulverizer. Available with capacities as low as 5 TPH up to 100 TPH, the 4-Row Cage Mill produces consistent product quality as an aglime crushing equipment.

**Limestone Quarry Increases Production Capacity to 1.5 Million tons Yearly**
Stedman Machine and Innovative Processing Solutions, an affiliate of Stedman, worked with Duff Quarry Inc. to incorporate two large industrial crushers to handle the size of limestone crushed annually. Their previous machines required a great amount of maintenance, but with Stedman machines, Duff Quarry Inc. spends less time fixing and more time crushing. With the installed plant and crushers, the quarry can produce up to 1.5 million tons of limestone a year running at full capacity.

Test Your Size Reduction Equipment Before You Buy
# Test Your Size Reduction Equipment Before You Buy
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Learn Why It’s Smart To Try Before You Buy Size Reduction Equipment
_By Chris Nawalaniec, Vice President of Sales & Marketing, Stedman Machine Company_
### **Why Test?**
[Size-reduction equipment](https://www.stedman-machine.com/particle-size-reduction.html) is typically integrated into a large system, so choosing the wrong equipment can inadvertently create a bottleneck that affects the productivity of your overall system, meaning long-term consequences in the cost of consumables, lack of production and downtime.
[Testing](https://www.stedman-machine.com/testing-facility.html) before you buy helps avoid these operational pitfalls by allowing you to determine the most efficient processing technology to meet your production needs. Our full-scale testing facility allows you to test a range of machines for your exact material and provides a demonstration of a specific model before purchase.
While lab machine tests are possible, they may not be able to determine the actual horsepower and machine size that your project requires. Testing with full-size crushing equipment is best for dependable results since it is difficult to scale up crushing results from a lab-size crusher.
## Benefits Of Our Testing Facility
✓ Access to hundreds of reports on file that provide valuable insight on how to configure equipment for a variety of applications
✓ Saves you the expenses of preliminary testing when selecting of the proper size reduction method
✓ Experienced staff can recommend machines based on existing reference data for similar applications
✓ Ability to test a range of different size reduction methods
✓ Demonstrates results in real-world conditions
✓ Can be operated in either open or closed circuit

### **What the test facility needs to know**
- Feed size
- Moisture content
- Tons-per-hour capacity required
- Final product size
- Safety data sheets
- For typical tests about 200 to 500 pounds of material are required
### What to expect during the test
### Step 1
| |
| --- |
| Sample the raw feed to establish the input gradation, moisture level and create a plan for crushing tests specific to the project goals. |
### Step 2
| |
| --- |
| Observing the testing process and all the procedures necessary to produce the required end product including preparation, loading of your material and RPM sets for fine to coarse production. You’ll witness the real-time horsepower consumption through start up and full load. |
### Step 3
| |
| --- |
| If needed, our test facility will run your material through various crushing methods and/or determine how to fine tune the crusher’s configuration for your process. Two different type crushers may effectively reduce your material at the specifications you need, but one may require much less horsepower and less cost to operate. |
### Step 4
| |
| --- |
| Receive a written technical report of the data produced from the test of your material which estimates operating costs and provides information needed to select the right crushing and size reduction equipment including: raw feed particle size distribution, power requirements for startup and operation, and analyses for moisture content, bulk density before and after crushing, abrasion testing, and product particle size distribution gradation. |
* * *
The goal of testing is to find an application solution rather than simply buying equipment. If you have any questions about our testing facility, or would like to set up an appointment to visit our testing facility contact us at (800) 262-5401 or [fill out a form online](https://www.stedman-machine.com/contact-us.html).

Material Receiving
# Feeder System for Conveyors
Whether feeding small batches from bulk bags or high capacity from dump trucks, we help you select the appropriate feeder systems for conveyors to ensure your process begins well.
Every processing system requires some form of material handling equipment. We select equipment that meets the needs of your project. Whether that means custom designing and fabricating a belt conveyor or working with other equipment manufacturers, we keep your material moving.
After [mining](https://www.stedman-machine.com/mineral-crushing.html) or production, dry solid material storage capacity must be matched to the entire system design.
[Ask a Question](https://www.stedman-machine.com/contact-us.html)

## Feeder System for Conveyors
Every material processing system has to have a starting point. Accurate, consistent feed rates are critical to ensure repeatable results in **[size reduction and separation systems](https://www.stedman-machine.com/particle-size-reduction.html)**. Overfeeding overloads conveyors and processing equipment, resulting in costly maintenance and downtime. Underfeeding robs production and increases costs.
Whether feeding small batches from bulk bags or high capacity from dump trucks, we help you select the appropriate feeder systems for conveyors to ensure your process begins well.
Typical feeding equipment includes:
- Apron feeders
- Belt feeders
- Vibratory pan feeders
- Vibratory grizzly feeders
- Screw feeders

## Bulk Material Handling Systems
Every processing system requires some form of material handling equipment. We select equipment that meets the needs of your project. Whether that means custom designing and fabricating a belt conveyor or working with other equipment manufacturers, we keep your material moving.
Improper design can cause a multitude of problems; spillage, fugitive dust, blocked chutes, uneven feed and accelerated wear on process equipment. We have the experience to design your dry bulk material handling system to eliminate these problems.
At Stedman Machine Company, we consider material characteristics, such as bulk density and material flow rates, as well as environmental factors when selecting and designing dry bulk material handling equipment. Thorough consideration is given to ensure the correct material handling solution for your unique project needs.
Typical dry bulk material handling equipment includes:
- Belt conveyors
- Stackers
- Bucket Conveyors
- Drag Conveyors
- Apron conveyors
- Screw conveyors
- Pneumatic conveying systems
## Dry Bulk Storage Solutions
Stockpiling and storing raw, in-process and finished dry solid materials requires storage strategies.
After mining or production, dry solid material storage capacity must be matched to the entire system design. Well-designed dry bulk storage solutions allow for a continuously running system and protect the material from start to finish.
Stedman Machine Company will analyze your project storage tank needs and recommend a best-in-class solution.
Material Storage solutions include:
- Hoppers
- Surge bins
- Silos
- Bunkers
- Weathering sheds
- Reclaimers
- Stockpiles

A&B Series Hammer Mill
# Industrial Hammer Mill Grinders
The ideal grinder necessary is determined by feed size, feed rate, operating conditions and desired product output for processing. Stedman offers two types of industrial hammer mill grinders, aka Animal Feed Hammer Mill, - Type A "Up Running" Hammer Mills and Type B "Down Running" Hammer Mills - that transform the consistency of soft and rough materials by using the pulverizing technique of a hammer mill grinder to produce a finished particle.

### What is the difference between A and B Series Industrial Hammer Mill Grinders?
"Up running," or the A Series feed grinder, provides multiple size reduction stages for materials, and "down running," or B Series Hammer Mills, are most suitable for fibrous materials due to high concentration of shearing actions within the unit.
[Have Questions? Ask Our Experts](https://www.stedman-machine.com/contact-us.html)
### Type A “Up Running” Hammer Mill Grinder
The A series grinder uses perforated screens or grate bars for reducing soft to medium hard materials. The material to be reduced determines the rotor construction of a Stedman Hammer Mill. The rotors used in the Type A hammer mills are adjustable to compensate for wear.
- Shattering by revolving hammers
- Impaction against housing liners
- Grinding on the adjustable grinding plate
- Shearing by the grate bars or screen
### Type B “Down Running” Hammer Mill Grinder
The B series grinder utilizes specially designed heavy reversible hammers, working in conjunction with Stedman’s adjustable breaker plate enabling the Hammer Mill to produce an exceptionally uniform product with the lowest possible maintenance.
If you're unsure which direction suits your material, **[contact Stedman](https://www.stedman-machine.com/contact-us.html)** to schedule your testing today!

### Minimize fugitive airborne dust
The energy put into crushing and separation of dry solids almost always generates ultra-fine particles that become airborne and end up as nuisance dust. We use our experience to design and install conveying systems, transfer points, receiving, loading, packaging and processing equipment to minimize fugitive airborne dust. We keep the material inside your system.
Working with partner companies, Stedman is able to design a proper industrial dust collection system to address your unique project requirements.
Some of the dust collection machines and suppression equipment we provide include:
- Bag house systems
- Cartridge style dust collectors
- Bin Vents
- Cyclones
Improper design can cause a multitude of problems; spillage, fugitive dust, blocked chutes, uneven feed and accelerated wear on process equipment. We have the experience to design your material handling system to eliminate these problems.

## New Stedman Machine Company Copper Line Cage Mill for the Distilled Spirits Industry
The Stedman Copper Line cage mill is engineered exclusively for the distilled spirits industry to enhance the flavor profile of the product because the open discharge eliminates grain scorching and prevents the introduction of unwanted flavors. The machine’s screenless design doesn’t restrict material flow or impart unintended heat to the grain as found with other size reduction machines.
The Copper Line is ideal for reducing batch milling time for corn, wheat, rye and barley. Three Copper Line models offer a wide range of production capacities between 100 to 665 bushels per hour. Capacities vary depending on the feed size, feed rate, operating conditions, desired product output, feed material characteristics and equipment configuration.
This specialty, low-maintenance cage mill was built to meet distilleries’ demanding grain grinding specifications. Copper Line cage mills produce either a fine, medium-fine or coarse grain size throughout the milling process depending on the spacing set between cages. The consistent, standardized grain size helps the distillery achieve the uniform flavor profile of the end product. Reversible cage direction extends the life of wear parts to minimize downtime. Stedman’s testing and toll processing facility can help determine the perfect grind for distilleries’ mash.

Limestone Quarry Doubles Their Production Capacity With Help From Stedma
# Limestone Quarry Doubles Their Production Capacity With Help From Stedma
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Limestone Quarry Increases Yearly Production Capacity up to 1.5 Million Tons With New Automated Plant Designed by Innovative Processing Solutions Using Stedman Size Reduction Impact Crushers
Duff Quarry Inc. (Huntsville, OH) began a new limestone crushing plant in the spring of 2005 to replace their previous plant, which had been running since 1956. While building and designing this new quarry, James Elder Duff, co-owner of Duff Quarry, focused on creating a state-of-the-art plant. “See, markets change and we wanted to go into something where we had the flexibility to do different things and different sizing,” Duff says.
In order to create a flexible, modern plant, Duff Quarry turned to Innovative Processing Solutions, an affiliate of Stedman, who designed and fabricated the automated material handling solutions for the quarry. Innovative Processing Solutions also used Stedman’s [Mega-Slam™](https://www.stedman-machine.com/mega-slam-impactors.html "Mega-Slam Impactor") and [Grand-Slam™](https://www.stedman-machine.com/grand-slam-impactors.html "Grand Slam Impactor") size reduction impact crushers at the new quarry, for [limestone crushers](https://www.stedman-machine.com/aggregate-crushing.html).
## History of Duff Quarry
Duff Quarry was started in 1956 by Clayton Elder Duff and his son, James Elder Duff, after the family had been in the sand and gravel business since 1951. Today the quarry provides limestone to areas within a 25-mile radius of Huntsville, Ohio for government applications, housing developments, [asphalt](https://www.stedman-machine.com/asphalt.html) facilities, ready mix concrete facilities and other public and privates uses. The quarry has even shipped limestone to California, Beverly, MA, Auburn, NY and Chicago for coal gasification, a process that pressurizes coal and stone to form natural gas.
James Elder Duff (Duff) and his two sons James Scott Duff (Scott Duff) and James David Duff (David Duff) are the sole owners of Duff Quarry. The Duff family also owns companies in the ready mix concrete and lumber industries. Duff is the owner of Ohio Ready Mix, David and Scott Duff own Ohio Lumber and David Duff is the owner of Mr. Concrete. Duff Quarry also supplies limestone to their Ohio Ready Mix and Mr. Concrete businesses.
Duff first learned about Stedman in 1956 or 1957 when the company purchased a Stedman 48” 4-row cage mill to make agricultural lime at their old quarry. At the time, the quarry’s previous equipment wasn’t able to handle the agricultural lime and it was decided to bring in a Stedman [cage mill](https://www.stedman-machine.com/cage-mill-pulverizers.html). Duff Quarry also purchased a portable plant, a 4860 Mega-Slam™ crusher, from Stedman for a different location in 1994. “We went to this crusher due to the fact that we felt it was a superior crusher with the portable plant that we were purchasing,” Duff explains. The portable plant allowed Duff to move the crusher to another location if needed.
## State-of-the-Art Crushing Plant
Duff Quarry now has a 5460 Mega-Slam™ and 6460 Grand-Slam™ crusher from Stedman at their new plant, along with a complete automated plant system from Innovative Processing Solutions. The design and fabrication for this new plant took nearly two and a half years to complete as each idea was considered and “wish lists” were sorted out. “When we were designing the plant I didn’t want to come back and say we should have done this or done that,” Duff states, “I wanted the very best of everything that we could get into the plant for longevity. I’m concerned about longevity, not just today.”
The Duff Quarry team of 12 employees kept the old plant running as the new plant was designed and later installed. The previous quarry was able to produce 600,000 tons of limestone annually, but the original crushers required a lot of maintenance. “I feel as though I’m fair in saying that these Stedman crushers will save 50% of the maintenance that we had in the other plant,” Duff explains. “I say that because the nature of this plant is so much different than the old one because of the welding needed on the crushers. At the old crushing plant we had to weld the crushers every 10 to 15 days.” The welding took about two days to complete, which cost the company hours of labor, not to mention the lost production and higher maintenance costs.
With the new plant and crushers the quarry can produce up to 1.5 million tons of limestone a year running at full capacity. And not only that, but the quarry has the capability to stockpile large amounts of finished product. “We have the capabilities of stockpiling 155,000 tons of rock underneath this plant,” Duff adds, “155,000 tons of finished product.”
Duff Quarry also purchased numerous conveyors, stackers, sensors, controls, vibrating screens, feeders and other equipment through Innovative Processing Solutions, an affiliate company to Stedman who designs and purchases equipment needed to help create an operating processing system. The quarry also received Apex electronics and control systems to create and design a programmable logic controller. Each conveyor at the crushing plant is equipped with terminal strips that are all wired to communicate information to one main processor. “There are too many conveyors for one guy to stand there and say he knows what’s going on. So this brings all of this information together in one place,” explains Bill Page, Maintenance Supervisor at Duff Quarry. Page worked with Apex in designing the control and information system.
All of the feeders and conveyors are monitored to give the company all of the information needed about the plant. “Every electric motor here tells the amp reading on it,” Duff says. “It’s a very important part in crushing equipment to know the amount of amps that electric motor is pulling. It tells us how many tons it’s pulling per hour, how many went through so far in a day and how many tons have gone through for the year.”
Duff Quarry also has the ability to run at full capacity during most weather conditions. The plant was designed to handle and adjust its screening procedure accordingly. “If we had two inches of rain come down tonight we could go in and make full capacity stone,” Duff says. “We could make really large rock and rock from one inch on down in size. This plant is designed with so much capability to do so many different things.” Duff also installed pumps and drain lines under the plant so that the plant cannot flood.
## Benefits of Automation
With the ability to monitor the speed of the conveyors and feeders, the quarry can keep an eye on production and can troubleshoot maintenance issues. “The reason for having an automated control system is that if something goes wrong on one of those conveyors, you aren’t going to see it fast enough to stop a catastrophe,” Page states. “And a catastrophe means that we have to dig out a conveyor. But now if something goes wrong, the computer takes over and begins dropping conveyors, discharging material and shutting the feeder down.”
Since the quarry can now monitor the conveyors moving, the speeds and the tons per hour, limitations can be set to help catch problems before they become too serious. “If something is going wrong, say this conveyor 2A is slowing down,” Page explains. “We can put limits on how much we want to allow it to slow down before the feeder is paused and then we can limit how long that feeder stays paused. Then hopefully the limitations will start clicking that feeder on and off so the operator knows something is wrong.”
With the automated plant Duff Quarry has the ability to run production all day, where the previous plant had to be shut down for lunch and then restarted. “This plant is run with two people,” Duff asserts. “We have an operator who starts in the morning and works until noon and then another operator gets on the loader and we never shut down.”
The automation gives Duff Quarry many benefits over their previous plant and over many other limestone quarries in operation today. “Right now you can go down and change this plant and the rock size within ten minutes,” Duff declares. “We have a conveyor with dual responsibilities where we could shut one size off and then go to another size and use the same conveyor to put the new size in the crusher. The automation that controls this plant far exceeds most other plants that I’ve seen.”
## The Future of Duff Quarry
Duff Quarry was able to more than double their production capacity with the help of the automated plant from Innovative and Stedman crushers at their new facility. “When we ordered the plant we received it as we had planned, no problems,” Duff notes. “Any help that we needed, which was a lot, we got from Stedman and Innovative. I can’t say anything but good things for what they’ve done for us.”
The Duff Quarry sits on a limestone reserve that runs 400 feet deep and covers 400 acres. Usually quarries can rate themselves depending on how long their reserve can last, generally in terms of years. But with this quarry the number of years seems endless with such a huge reserve of limestone. Duff Quarry will be able to continue their crushing plant far into the future and into the next generation of Duffs. “I feel sure that my grandsons will work harder in developing something special out of this stone,” Duff comments. “They’ll be doing more fine grinding and coming up with a product. And that’s the future in aggregates today.”

The Five Hazardous Co-Workers
# The Five Hazardous Co-Workers

## Which One Are You?
By Eric Marcotte
Safety is everyone’s responsibility and everyone’s problem. It is critical to the safety of the operator and others that reasonable care and judgment is exercised. Here are five bad personality types paired with examples of the most common Occupational Safety & Health Administration (OSHA) safety violations for 2018 as they apply to impact crushers. We specialize in impact crushers such as cage mills, horizontal/vertical shaft impactors and air swept fine grinding mills. Next to conveyors, potentially some of the most dangerous quarry equipment to work around. Despite all the advancements in technology to improve quarry safety, one factor remains the same: the human factor, which leads to errors. Most accidents are caused by failure to observe simple safety rules and precautions. Operators must be aware of what is happening around the working area to recognize hazards before they become accidents and to avoid creating situations, which could cause accidents or hazards. Operators must also be aware of their and their co-workers’ hazardous thoughts. Thoughts that disregard rules and regulations, common sense and physics! It’s everyone’s responsibility to recognize hazardous attitudes and stop them before any action is taken.
### 1\. The Resignator! - “What’s the use?”
Lack of personal protective equipment (respiratory and eye/face) is the fourth and tenth most common violation in OSHA’s yearly report. “What’s the use,” you might say. Resignation to a problem isn’t a solution. Don’t get a rock chip in your eye because you wanted to be a “nice guy” and not ask someone for eye protection. Whether or not you get a respiratory illness from breathing rock dust isn’t a matter of being lucky or not. When things go badly, it won’t be because someone is out to get you, it's because you didn’t wear a respirator specifically approved for the hazard. What’s the use? The benefits are you’ll have happy employees, higher uptime, easier troubleshooting and reduced off-spec product. The National Institute for Occupational Safety and Health (NIOSH) has just released a beta version of monitoring software that will help mines more effectively monitor worker exposure to hazardous respirable crystalline silica. The antidote to the Resignator is: “You’re not helpless. You can make a difference.”
### 2\. I’m Invincible! – “It won't happen to me.”
Lack of proper machine guarding is the ninth top OSHA violation. Many people believe that mishaps happen to others, but never to them. They know mishaps can happen, and that anyone can have an accident. However, they never believe they will be involved. Persons who think this way are likely to take chances, increasing their risk. Who is responsible? It takes leadership management with the commitment, to empower facility managers to get employees engaged. Machine guarding is only the last defense. You should also remove rings, necklaces, jewelry, and neckties. And not wear loose fitting clothing, to not put you in the position of the person who got their clothes caught in a rotating drive draft, drawing them into the machinery. The antidote to invincible thinking is: “It could happen to me.” 3. Get’er Done! - “Do Something Quickly.” Accidents with powered, industrial load carrying equipment are the seventh highest violation rate. Jumping onto a forklift to “Get it done right away” may not be the right action. Some people frequently feel the need to do something immediately. They do not think about what a risk they are taking or evaluate the best choice. Doing the first thing that comes to mind is almost never the best decision. What could go wrong at your plant? Review your safety issues during the specification and commissioning of equipment. Question how the use of forklifts, front-end loaders, trucks and man lifts be used, equipment tested, personnel trained, supervised and new risks assessed? Clearly, mark traffic paths and include blind corner fish-eye mirrors. Is the cribbing you placed to repair a flat tire appropriate for a front-end loader? Is that lifting chain properly rigged? When working near equipment, make eye contact with the equipment operator and directly communicate your intended movements. Before you jump in that man-basket secured to a shovel by a weldment that doesn’t look right to get the job finished, think, “Why rush into this?” The antidote to impulsivity is: "Not so fast. Think first.”

### 4\. Macho, Macho, Man! - “I can do it.”
Lockout/tagout violations were the fifth most frequent violation in 2018 thru Sept. 30. Taking chances is foolish. Persons like this are always trying to prove that they are better than anyone else. Thinking, “I can do it—I'll show them.” Persons like this will try to impress others by taking risks. How does your plant handle operational safety issues? Do you have regularly scheduled maintenance and inspections logs? How clean is your quarry? Are the proper spare parts available? Is it easy to find out how to properly service and maintain your equipment? Dust control guarding is also important for cage mils, which can create dust issues because the cages act as fans. 3 Never troubleshoot electrical systems when you can come into contact with the high voltage typically found in control centers. Always install the necessary lockouts and tags needed to isolate equipment from power sources before removing any guards or covers or performing any maintenance or adjustments. Standing on an energized conveyor is never a good idea, and pulling the stop cable isn’t a lockout! It’s not rocket science, but in 2018 the Mine Saftey and Health Administration awarded Penn State University $50,000 to plan, design, develop and evaluate a three-module training program that will enhance safety regarding inspecting, working around and performing maintenance on conveyor belts. The antidote to being macho is: “There are old quarrymen and bold quarrymen. There are no old, bold quarrymen.”
### 5\. Anti-authority! - “Don’t tell me.”
General fall protection is the number one violation! Some people do not like anyone telling them what to do. They are thinking, “I’m not going to fall, one hand for the man, one hand for the ship,” is my motto! They may regard rules, regulations, and procedures as silly and too time-consuming. It's always your prerogative to question authority if you feel it is in error. Do you know the Health, Safety and Environmental regulations for your operation? The HSE safety goal is “Less than one workday lost per million hours worked.” Where are your Safety Data Sheets? NIOSH offers Hazard Recognition Programs and Toolbox Talks to bring your crew up to speed. Quarries have many high places to fall from. Even falling off of a portable plant while stationary can be fatal. The antidote to anti-authority is: “Follow the rules. They are usually right.”
### Summary
Business is good, now is the time to review your safety programs for continued profitability. Specific requirements, precautions, and hazards associated with impact crusher equipment operation and the general work area must be communicated to, and understood by, all persons involved in the operation and maintenance of this equipment in order to avoid injury or death to personnel, or damage to the equipment. Heavy equipment operation - is decision-making in a unique environment — pits and quarries. Mining is not possible without risk, but unnecessary risk comes without a corresponding return. Make it a systematic approach to consistently determine the best course of action in response to a given set of circumstances. The five steps for good decision-making are: 1. Identify personal hazardous attitudes, 2. Use behavior modification techniques to diffuse them, 3. Recognize and cope with stress, 4. Develop risk assessment skills, and 5. Use all available resources. Vertical Shaft Impactors operate at higher speeds than most crushers and typically require automatic oil feed lubrication systems, another thing that can go dangerously wrong if not maintained. 4 Maybe it will be a video game that helps you develop a culture of safety, which means empowering employees to make observations, report unsafe conditions and have the authority to stop work without retribution. Recently NIOSH funded a $1.6 million grant to develop more effective mining safety training methods. Researchers will develop training that uses “serious” computer games designed to replicate a realistic mining environment where mineworkers will be put in dynamic situations to make decisions and see the consequences. Proper training is one of the most fundamental requirements for successful, reliable production. Begin with the crusher’s operation and maintenance manual. Incorporate the manual’s suggested routine maintenance schedule into the maintenance team’s duties. Appoint a “lead person” for each crusher as the go-to for that machine. This person is the historian for the unique operational adjustments the producer has incorporated for raw feed and product requirements. Equipment manufacturers are the final word on any and all issues with their products, if you’re not sure what you’re doing is right, ask them. There are no dumb questions.

Get BIG Impact From Your Crusher Performance
# Get BIG Impact From Your Crusher Performance
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Get More Performance Out Of Your Crusher
There’s an urban legend out there about the company whose maintenance crew mistakenly installed a new [crusher](https://www.stedman-machine.com/impact-crushers.html) with the rotor spinning backwards. It still worked! And you think you have issues?
To get the most from your equipment investment, you need to put in the time. Yes, a crusher costs a bit more than your average automobile, but that doesn’t mean it’s maintenance-free. An automobile needs oil changes too, right? Performing regularly scheduled maintenance on impact crushers is crucial for guaranteeing day-to-day reliability and optimum product output. Did you know you can boost output and quality by doing just a little bit more? Even daily cleanups and inspections can increase service life. It’s a no-brainer, though possibly easier said than done. Here are some steps and practices to incorporate in your ongoing operations and maintenance. Beginning with maintenance team education, parts logs, and general maintenance record keeping, plus troubleshooting, these guidelines will help your crusher go the distance.
### Training:
- Proper training for consistent maintenance is one of the most fundamental requirements for successful, reliable production. Begin with the crusher’s operation and maintenance manual. Incorporate the manual’s suggested routine maintenance schedule into the maintenance team’s duties. Appoint a “lead person” for each crusher as the go-to for that machine. This person is the historian for the unique operational adjustments the producer has incorporated for raw feed and product requirements.
### Daily log (document the following every 8 hours):
- Amperage draw: See if it changes from day to day. If amperage is exceeding normal levels, it could be a signal of bearing problems, loose belts, or general feed issues.
- Coast-down time: You’re going to need to know (and log) how long it takes the machine to come to a complete stop after shutdown. Here’s why: If the time starts to shorten, this could indicate a bearing problem.
- Oil pressure: You’ll want to record performance in a variety of operating conditions. This will allow you to identify trends and help to detect problems before they cause costly damage or downtime.
### Daily maintenance (every 8 hours):
- Check oil level, sight glass, grease appearance, and other lubrication schedules.
- Check high temperature or low hydraulic pressure indicators and switches.
- Check wear parts.
- Tighten bolts.
- Inspect belts.
- Remove dirt and debris from crusher frame surfaces and areas around the machine.
- Check intake/discharge chutes for any obstructions and/or build up.
- Check alarms. If electrical changes are made or programs are altered in automated systems, verify that all alarms and interlocks function properly. Don’t be afraid to replace switches or timers that appear damaged or are in poor condition. This is more economical than a major overhaul, but never disable or alter any alarms or interlocks!
### Lubrication:
- Completely drain and thoroughly clean out the inside of the oil tank (if you have one) to eliminate any contaminants before refilling.
- Find contaminant sources. Contaminants such as dust particles and water can get in where oil leaks out.
- Inspect hydraulic systems and tag any leaks for corrective action on the very next maintenance cycle.
- Use the proper grade of oil.
- Use the proper specification of filters.
- Keep the oil breathers clean.
- Understand grease versus oil lubrication. Grease requires less-intensive maintenance than that of oil-lubricated systems. Automatic oil lubrication systems or sealed cartridge bearings are for higher speed crushers like vertical shaft impactors, air swept fine grinders, or high-speed cage mills. Most horizontal shaft impactors, hammer mills, and cage mill applications are below 1,000 rpm and grease is sufficient.
- Maintain a scheduled oil sampling program. By creating a baseline of normal wear, it helps indicate when abnormal wear or contamination is occurring. The exact condition of a mechanical assembly is reflected in the oil.
### Belts:
- Inspect V-belt drives for damaged belts or loose belt tension. By replacing cracked, glazed, torn, or separated belts, plus maintaining proper belt tension, you’ll optimize your plant’s performance.
### Wear parts:
- Don’t overextend wear parts. Avoid running them so long that they become too worn. You may find that you can no longer rotate breaker bars or interchange wear plates to lower wear areas — and now, you’ve lost half of the wear.
### Guards:
- Rubber and chain curtains located in the feed and discharge openings of the crusher are subject to wear and tear. Since they are a first line of protection, it’s important to inspect them regularly and to establish a schedule of regular maintenance.
### Electrical:
- When (or if) electrical changes are made, you’ll need to verify that all alarms and interlocks still properly function. Same goes for programs when altered in automated systems. Always check with the manufacturer before making any modifications.
### Spares recommendation:
- Keep the recommended spares on hand and order replacements as soon as they are used. A list of recommended spares may be included with your equipment operations manual. If not, contact the manufacturer for recommendations.
### Update your equipment:
- All equipment evolves, and the recommended manufacturer upgrades are a good investment for increased life and better crusher performance. Check with the manufacturer for any possible updates.
### Unapproved modifications:
- Manufacturer design engineers have considerable field experience, which helps them as they calculate the design and perform prototype testing. Their engineering tasks include calculating bearing loads and bearing clearances. They’ve also worked to maximize throughput by establishing the most efficient speed and setting combinations to optimize impact on the material undergoing reduction. So when plant personnel suggest modifications that alter the intended design, these changes will more than likely hurt the purpose of the original design. As a result, you’ll have a less productive and reliable crusher due to potential damage and overload. Since the manufacturer has a vested interest in how well the crusher performs, contact them before making any modifications

## Cage Mill Operation and Maintenance
### Requirements for optimum production and wear part utilization include the following:
- To increase multi-cage sleeve life, cage rotation should be reversed regularly, if possible. (Some cage mills can be reversed, while others cannot.) By reversing the cage direction, sleeves will be worn from both sides, thus extending wear life.
### Wear parts:
- Index and or replace sleeves periodically.
- Inspect or replace hopper ring and shaft protector, if needed. Cage rebuilding is an option.
### Bearings:
- Follow the manufacturer’s recommended specifications and schedule for lubrications, temperature, and vibration ranges of spherical roller bearings in pillow block housings.

## Horizontal Shaft Impactor Operation and Maintenance
Variables affecting product gradation include the following:
- Rotor speed – Higher rotor speeds produce finer product output.
- Apron gap settings – Closer gaps retain the feed longer producing a finer product.
- Breaker bar wear – Regular inspection and turning will lower operating costs.
- Throughput (tons per hour) – Overfeeding a crusher can make the output more coarse, but it also causes a number of wear and longevity issues making overfeeding a major concern to avoid.
- Moisture – Moisture cushions the impact, producing a coarser product.
- Apron wear – Worn plates can be replaced or moved to areas of lower wear.
- Spring bridge operation – Spring set height is critical to maintain proper operation of spring bridges. Spring bridges return the aprons to their original positions after an overload situation. The use of altered or non-specified springs can cause equipment damage or catastrophic failure.
### Requirements for optimum production and wear part utilization include the following:
- Protect inlet and outlet.
- Restrict maximum feed size.
- Maintain feed rate within allowable limits.
- Check rotor rotation.
- Use metal detection (required).
- Check for wear.
- Follow recommended breaker bar rotation setting sequence.
- Check rotor breaker bar, wedge, and stop block or jack screws.
- Check liners and breaker plates.
### Wear parts:
- Impact Plates
- Breaker Bars
- Housing Liners
- Wedges & Retainers
- Bearings & Seals
* * *
* * *
## Vertical Shaft Impactor Operation And Maintenance
The vertical shaft impactor uses high rotor speeds (1,000 to 3,000 rpm) to apply high energies to the material, and since Energy + Material = Size Reduction, it can create sand from 2-inch feed.
### Requirements for optimum production and wear part utilization include the following:
- Limit feed size.
- Use metal detection (required).
- Observe any vibrations with the use of continuously monitored vibration sensors. Listen to the equipment, if something sounds unusual, shut down and inspect.
- Limit recirculating product in a closed system.
- If using water for dust suppression, introduce it into the discharge area if possible. Introducing water in the intake will increase wear.
- Place weight match shoes opposite one another.
The image above shows rotor tubes indexed 90 degrees providing a new wear surface.
### Wear parts include the following:
- Shoes and tubes
- Anvil ring or other inserts
- Housing liners
- Rotor table liners and assembly
### Spares recommendation:
- Shoes (one complete set)
- Table liner
- Anvils (one complete set)
- Discharge plate
The spare parts inventory shown above is recommended for vertical shaft impactors.

## Hammer Mill operation and Maintenance
Up running [hammer mills](https://www.stedman-machine.com/hammer-mill-crushers.html) combine impact and shear to reduce material. Down running hammer mills primarily use shear by immediately taking feed to the screen or grate bars where hammers shear the material, until it passes through the openings.
### Requirements for optimum production and wear part utilization include the following:
- Lubricate bearings regularly.
- Regularly inspection (unclamp or unbolt front upper half housing for access to screens and hammers) liners, hammers, hammer bolts, rotor discs, grate bars, and screens.
### Spares recommendation:
- Hammers
- Screens
- Liners
- Grinding plate

## Summary
A partnership begins between the manufacturer and the customer when the crusher is installed in the field. The manufacturer needs the customer’s help as much as the customer needs the manufacturer’s help to achieve the highest performance possible. Maintenance service after the sale, although mentioned last, is a central part of crusher system performance. And just in case, the manufacturer will have the people and the parts available 24/7 to assist with any problems.
Regardless of the field application, the training of personnel is key to successfully and optimally operating equipment. For the size-reduction industry, crusher maintenance problems are mostly related to inadequate training. This exists at plants both large and small. The most effective education is a current and ongoing program for crews — and that’s what will result in legendary performance.

Distillery Milling Efficiency
# Distillery Milling Efficiency
[Contact Us](https://www.stedman-machine.com/contact-us.html)
_Eric Marcotte is the inside sales manager for Stedman Machinery Company_
Archeologists and historians have debated the early origins of alcoholic beverages with evidence of wine grapes dating back 10,000 years. Some believe wine came first, eventually followed by an accidental mash-up of grain and water that yielded beer, but distilled spirits are definitely in the mix and the milling. The Old Bushmills Distillery in Northern Ireland is the oldest licensed whiskey distillery in the world, with its license issued in 1608.
So what has changed with whiskey distilling over time? In a word efficiency. The steps to convert raw grains into the myriad of beverages millions enjoy today remain largely the same. However, the processes have been refined or streamlined and are now considerably more efficient.
### Starting with Grains
Let’s take stock of the steps to produce whiskeys beginning with milling. [Distillery milling](https://www.stedman-machine.com/distilleries.html) breaks up cereal grains so that water can penetrate and facilitate the cooking process. Grinding increases a grain’s surface area. More surface area gives water and enzymes a better opportunity to penetrate the grain. A particle 1 inch in diameter has a total surface area of 3.14 square inches. If you divide that particle into 1,000 particles, surface area becomes 31 square inches.
The optimal size of the ground material varies according to the master distiller. Some think particles should be fine to allow maximum access for hydrolysis of starch, while others propose that larger particles provide better yield. Regardless of size, the idea is to expose the starch to water in a way that won’t cause handling problems. If the mash is too hard to de-water, then the distiller may lose liquid containing alcohol, decreasing yield.
Particle size distribution analysis of the meal should be performed on a regular basis. When the distribution falls outside specifications, the mill should be adjusted.
### Machinery Types
Grinding corn, rye and malted barley in distilled liquor production call for equipment performance typically required in food plants. The grain must not be overheated in the grinding process because it could affect the flavor of the final product, and the ground grain must be uniform, relatively coarse, and contain as little flour, or dust, as possible to prevent handling and dewatering problems.
Generally, a [hammer mill](https://www.stedman-machine.com/hammer-mill-crushers.html) is used for corn, wheat and rye; a roller mill for malted barley; and a [cage mill](https://www.stedman-machine.com/cage-mill-pulverizers.html) for all four.
### Hammer Mills
[Hammer mills](https://www.stedman-machine.com/hammer-mill-crushers.html) use rectangular pieces of hardened steel attached to a shaft rotating at high speed inside the milling chamber. The hammers accelerate the grain into breaker plates lining the housing of the mill. Next, the grain encounters a changeable screen with a “close tolerance” gap between it and the rotating hammers.
Unique to hammer mill grinding is that material must pass through the screen to exit the mill. This guarantees the final product maximum size. Hammer configuration, rotation speed and screen sizes can be varied to process different grains, and each component can be changed individually. More hammers, faster speeds and finer screens produce a finer grind.
Hammer mills eliminate the need to screen product. However, when you fine-grind with a hammer mill, it may take more power per ton, and maintenance costs may be higher compared to roller mills. Master distillers should also consider that they could overgrind or create too many fines.
### Roller Mills
Roller mills use compression to reduce the size of the grain as it passes between stacked pairs of rollers. The smooth rolls may turn at different speeds to introduce shearing forces, and the addition of grooved rolls adds tearing and grinding to the milling actions. Their slow speed doesn’t cause grain to heat or lead to related moisture loss.
Roller mills produce only small amounts of fine materials, keeping dust down. The shape of the particle at the end is irregular, cubical and spherical so the grain doesn’t tend to pack or become a solid mass. Bulk density is about 10 percent less than grain milled by a hammer mill, as the ground material is coarser.
Roller mills have a larger capital cost but use less horsepower per ton, and they may require screening to get a specific grain size distribution. Because it is an abrasive grain, corn may wear out a roller mill.
**Cage Mills**
A [cage mill](https://www.stedman-machine.com/cage-mill-pulverizers.html) consists of one or more rotating cages enclosed in a steel housing. Material to be ground is fed into the center of the revolving inner cage and passes outward through centrifugal force from row to row, before finally discharging through the bottom of the mill.
The source of [size reduction](https://www.stedman-machine.com/particle-size-reduction.html) in a cage mill is the result of impaction between the material being fed and the pins of the revolving cages. Impact-type grinding in the mill does not cause excessive heat and produces a uniform grind with minimum flour. Cage mills are used for larger production batches or continuous operations for corn, wheat rye, malted barley and other grains.
Properly setting the speed of the cages allows the succeeding rows to act on the particles that have not yet been reduced to the desired size, moving from the innermost rows outward. Particles that have been crushed sufficiently tend to pass through the subsequent rows without being materially affected, so adjusting the speed of the cages controls over-crushing and under-crushing.
Compared to other size reduction methods, the cage mill does not have close clearances between the crushing parts, and it therefore requires less maintenance. Also, they do not require grate bars or screens for final product sizing. Cage mills produce a cubical product of consistent particle size distribution. The quality of production doesn’t decrease even over long periods of operation.
### Final Considerations
Beyond machinery, the coarseness of grinding grain affects the end product. Fine versus coarse grind can cause a 5 to 10 percent difference in alcohol yield. An upper limit of about 20 percent alcohol is possible with a very fine grind, but the flavor may be altered. Also, finer grinds may be harder to press, and some yield may be lost.
More data on grinding for distillation is available, and the distilling community is prepared with helpful advice for nearly any situation. Part of the equipment choice may be the preference of the master distiller. Good milling equipment companies will help test your process on scalable equipment before purchase. The best manufacturers also offer toll-processing services for batches large enough to improve your processor for experimentation with new ingredients and grind specifications.

# Grand-Slam™ Impactor, Size Reduction and Horizontal Shaft Impactor Reduces Metal Replacement and Overall Operating Costs
[Grand-Slam™ Series HSI](https://www.stedman-machine.com/grand-slam-impactors.html), Horizontal Shaft Impactor, from Stedman Machine Company uses high-chrome metallurgy to significantly increase the wear life of machine components, reducing metal replacement costs. The size reduction crusher tackles a variety of applications from aluminum dross and clay to floor tile and scrap carbide recycling, reducing material size more efficiently with maximum up time. The Grand-Slam™ Impactor’s single drive design uses less horsepower per ton when compared to dual-drive systems, lowering operating costs.
The Grand-Slam™ Series consists of 10 high-production models with test capacities ranging from 5 to 700 TPH. The impactor design incorporates both primary and secondary aprons for maximum product control, eliminating the need for high-maintenance grate bars and discharge screens that often clog. The impactors' two-stage crushing action is designed to produce more product on the first pass with reduction ratios up to 30:1, even while handling large and slabby feed material.
A full-length rotor shaft with 2, double-row spherical-type bearing assemblies features a taper lock design to strengthen the rotor for highest reliability. The rotor features either a 2-row, 3-row or 4-row breaker bar design, depending on machine model size. A wedge locking design secures the breaker bars in place and simplifies breaker bar servicing. The high chrome breaker bars can be rotated multiple times before replacement, optimizing metal utilization and wear life. The rotor lock table, a Stedman-exclusive, facilitates breaker bar rotation and replacement, saving time and further optimizing wear life. For unimpeded access to the crushing chamber, either front or rear opening housings are available to meet customer system designs.
In conjunction with the rotor, the Grand-Slam™ Series primary and secondary aprons make up the impactors' two-stage crushing action for increased throughput. Both the primary apron, where initial size reduction occurs, and secondary apron, where final reduction takes place, is lined with interchangeable 3" thick tapered, high-chrome liners for maximum wear life. Both aprons are manually adjustable from the external housing for precise gap adjustments. For additional product control, an optional secondary apron spring bridge assembly provides additional force to maintain gap settings yet allows for retraction of the apron under extreme loads and immediately returns to original setting.
Side liners of the Grand-Slam™ Series come in only 3 different shapes - triangular, rectangular and square - and are interchangeable from model to model to reduce maintenance and inventory costs. The 2" thick, high-chrome liners are designed to withstand the abuse of impacting even the toughest materials for long wear life.
A variety of optional equipment is available for [Grand-Slam™ impactors](https://www.stedman-machine.com/grand-slam-impactors.html), so customers can outfit their machine to meet specific application requirements. Apron heaters, installed on the feed chute and primary and secondary aprons, minimize buildup when reducing wet and sticky materials. To minimize cross-color contamination, customers can use the optional air cannon, which discharges a blast of air into the crushing chamber to quickly dislodge material buildup. Together with the cannon, elimination of ledges and minimal ribbing allow for faster crushing chamber clean out. The optional variable-speed drive allows for on-the-fly product gradation changes to enhance peak operating efficiency.
As with all Stedman products, the customer is encouraged to test each application before purchasing a Grand-SlamTM. Stedman uses only full-size equipment to test a wide variety of materials to enable customers to select the best machine for the application. With a sample of feed material, Stedman engineers will conduct an application analysis and provide a confidential, written report of their findings to the customer. Stedman can also produce an analysis by using one of over 10,000 application reports on file.

Stedman Crusher Reduces Production Time for Continental Brick
# Stedman Crusher Reduces Production Time for Continental Brick
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Keeping the Kilns Burning at Continental Brick
After two decades of service, Continental Brick began to have problems with their hammer mill crusher. As a solution, Innovative Processing Solutions specified a Stedman size reduction impact crusher and engineered a design to work the brick crusher into the existing system. The Stedman crusher easily handles Continental Brick’s 12” material and reduces lost production time.
_**Continental Brick (Martinsburg, West Virginia)**_ has been successfully manufacturing face brick in the same location since 1917 using the same material from the Martinsville Shale Formation located within a mile of their plant. Their product line includes face brick used in residential and commercial applications primarily in the Northern Virginia, Pennsylvania, Chicago, New York, Washington D.C. and Baltimore areas. Through the years, they’ve upgraded equipment based on their capital equipment budget availability.
But as Don Sult, VP Operations at Continental states, “It has taken a lot of smart, hard working people and their dedicated time and attention to make things…including some older workhorse equipment…operate efficiently.”
## Grinding Operations Needed To Keep Up With The Rest Of The System
But a problem arose in early 2006…
Their hammer mill crusher was starting to wear out after two decades of service. “It was just taking too much of our maintenance time and expense to keep our grinding operations running at needed productive levels (60 million standard brick equivalent/annually),” states Sult. He adds that this older equipment had numerous replacement parts to manage and there were no automatic systems on it (i.e. automatic opening, etc.). It took the company hours to do simple routine maintenance or repair because they had to unbolt the cover and remove it just to gain access to the working mechanisms. On average, their uptime availability was approximately 90% with their old hammer mill.
Continental Brick called Innovative Processing Solutions for turnkey answers. The first step was determining the best replacement equipment, the second, engineering the solution to make it fit into the existing system.
## Step One: Find The Best Replacement Grinder
Material testing was conducted and Innovative engineers specified a [Stedman Grand-Slam™](https://www.stedman-machine.com/grand-slam-impactors.html) Model GS4860 Impactor to replace the existing hammer mill. Specific details about the Grand-SlamTM include:
- Reduces 12” shale to -6 mesh—all in a single machine (capable of reduction ratio up to 30:1)
- 150-180 tph capacity range
- Front opening housing for easy maintenance and inspection
- Reduced maintenance and operating costs
- Open discharge with no screen to plug
- Designed with interchangeable wear plates
- Heater and air cannons added to help process wet/sticky materials
“We’re impressed with the ability of a single machine to handle our 12 inch material and give us the final output we need (-6 mesh) — and without needing to rework our system’s circuit design,” said Sult.
## Step Two: Retrofit The Design To Work With Their Existing System’s Circuit
Retrofit engineering and installation of the Grand-SlamTM to the existing frame was a big challenge. Modifications were made, including a feed chute design to fit the new stand and crusher for proper material feed into the crusher’s inlet. With only five days to complete the installation before the shale inventory was depleted, Innovative personnel found cracks in the old frame. A new frame (10’ x 15’ by 10’ high) was quickly fabricated to replace it and production schedules were met.
“Innovative really kept their promises…and that’s critical to us. It would have cost us a lot of time and money to shut down these kilns,” added Sult. “They engineered a solution in about a day, delivered and installed the entire system in less than one week, saving us a four to six-week shutdown and more money in lost production than I care to think about!”

## All You Need to Know About: Vertical Shaft Impactor (VSI) Primers
_By Eric Marcotte, Inside Sales Manager, Stedman Machine Company_
### What Is VSI?
All roads, you might say, lead to the Vertical Shaft Impactor (VSI) because these crushers make it possible to create roadways and just about everything else. Francis E. Agnew of California patented one of the first Vertical Shaft Impactors in 1927. His configuration stacked three VSIs atop each other to produce sand, thus starting the VSI evolution.
Today, VSI crushers – and the folks who rely on them – have produced many configurations to include everything from the addition of cascading material into the crushing chamber, to air swept separation of lighter product. One version suspends the shaft from above like a sugar centrifuge. It’s also one of the most feature-patented crushers, so some of the things mentioned here might be unique to a single manufacturer. VSIs apply a large amount of energy to crush material and that’s why it’s one of the most versatile crusher configurations today.

### VSI Benefits
When it comes to producing materials such as aggregate for road making, [VSI crushers](https://www.stedman-machine.com/v-slam-impactors.html) use a high-speed rotor and anvils for [impact crushing](https://www.stedman-machine.com/impact-crushers.html) rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or minerals. The product is generally of a consistent cubical shape, making it excellent for modern Superpave highway [asphalt](https://www.stedman-machine.com/asphalt.html) applications. The rotor speed (feet per minute) controls final particle size.
The VSI’s high cubical fracture percentage maximizes first-pass product yield and produces tighter particle size distribution. It has a high-throughput capacity ideal for beneficiation (elimination of soft material). Properly configured the VSI accepts highly abrasive materials. It has simple operation and maintenance. You can quickly change product size by changing rotor speed or cascade ratio. Some models have reversible wear parts to reduce downtime. The VSI typically has low operating costs even in high-moisture applications because of reduced energy costs and low wear cost per ton.
### VSI Disadvantages
There are some feed size limitations with a VSI because of the small feed area available in the center of the rotor. Tramp material in the feed such as gloves, tools, etc. can cause problems with imbalance. The high RPM and HP require careful balance maintenance such as replacing shoes on both sides of the rotor at the same time. High wear part cost may be a problem for some hard abrasive materials, but the VSI may still be the best option.
### VSI Applications
Major [limestone applications](https://www.stedman-machine.com/aggregate-crushing.html) are for Superpave asphalt aggregates, road base, gravel, sand and cement. Industrial uses include: corundum, corundite, ferro silicon, glass, refractories, silicon carbide, tungsten carbide and zeolite. [Mining applications](https://www.stedman-machine.com/mineral-crushing.html) include: bauxite, burnt magnesite, iron [ore](https://www.stedman-machine.com/mineral-crushing.html), non-ferrous metal ore, perlite and trona sulfate. VSIs are excellent for everything from abrasive materials to waste and recycling applications.
### VSI Crushing Method
The VSI is typically used after a primary or secondary crusher. This makes a VSI ideal for making sand and for making coarse and medium aggregates for concrete/asphalt production.
Feed size and characteristics will affect the application of a VSI. The feed size is limited by the opening in the center of the rotor. Normally less than 5-inch material is desired, but very large VSIs can handle up to 12-inch feed. Another feature that will affect application is moisture, which can make the feed sticky. Required production capacity is the final limiting criteria. Large primary horizontal shaft impactors can output up to 1600 TPH and more. 1000 TPH is about the maximum for a VSI because of the limiting motor size and the rising G-force of a high-speed rotor, which is calculated by multiplying the radius times the square of the RPM.
Shoe configurations are many: rock on rock, groups of rollers, special tip wear parts and many others. The metallurgy of the shoes is also highly varied. Rotors can have three to six shoes. The number of shoes is typically governed by the diameter of the rotor. The larger the diameter rotor, the more openings are possible. Computational Fluid Dynamics (CFD) mathematical models are utilized to simulate the flow and collision forces to reveal solutions for lower wear cost, consistent final product, and higher energy efficiency.
The material to be crushed is fed into the center of an open or closed rotor. The rotor rotates at high rpm, accelerating the feed and throwing it with high energy into the crushing chamber. When the material hits the anvil ring assembly, it shatters, and then the cubical shaped product falls through the opening between the rotor and the anvil and down to the conveyor below.
The rotor speed (feet per minute) controls final particle size. Speeding up the rotor will produce more fines, slowing it down will produce fewer fines.
## Feeding Methods
### Center feed
The typical VSI is fed, from above, into the center of its rotor. The material is then flung across an open void to the crushing chamber. It then impacts the outer anvil ring. This crushing action imparts very high energy to the material and is very effective on most types of material. It gives a very uniform and consistent grade of product.
### Cascade feeding
In cascade feeding, material bypasses the rotor and enters the crushing chamber from above. It’s called cascade feeding because as material fills up a large feed bowl, with an outer diameter larger than the outer diameter of the rotor, it spills over the side and falls into the crushing chamber from above, bypassing the rotor. The effect of increasing feed through cascade is similar to slowing the rotor. Cascade feeding in amounts up to 10 percent may have no effect on particle size distribution or quality. The product gradation curve and product shape will change, if an increased amount of cascade feeding is used.
_Above: Vertical Shaft Impactor, No Cascade vs. With Cascade Feed, Particle Size Distribution Chart)_
## Rotor and Anvil Configurations
The VSI features multiple rotor/anvil configurations for various applications. From open or enclosed rotors to the tubular rotor, each machine is configured for their unique application. In many cases the rotor table, rotor assemblies, anvil ring or rock shelf are interchangeable, allowing maximum application flexibility.
### Open top metal rotor shoe on metal anvil
The open top metal rotor is good for large feed or medium to very hard material, but it will work best for softer materials. It can handle medium abrasive, dry or wet, but not sticky materials. High reduction ratios are common, which are excellent for sand and gravel production in closed loop systems. Shoe shape can change the production size range. A straight shoe face design produces finer product, and a curved shoe face design produces coarser material.
### Tubular metal rotor shoe on metal anvil
The tubular rotor creates higher tip-speeds, which increases first pass yield with tighter particle size distribution and also reduces the recirculation loads. One unique feature is that the rotor rotation is reversible, allowing wear on both sides of the tube. Rotating the tube itself one-quarter turn also doubles the wear.
### Enclosed metal rotor shoe on metal anvil
The enclosed top plate on a rotor primarily prevents material from escaping from the top of the rotor, which could happen with an overfed open top rotor.
_(Above: Rock shelf when VSI at rest. In operation, the brown rock fills the chamber to the upper roof ring. Rock impacts rock in operation.)_
### Enclosed autogenous rock rotor table on autogenous rock shelf
Any time the material or rock is used as an impact wear surface the term autogenous is used. Putting a top on the rotor table and shoes allows autogenous use. During operation of the VSI, a bed of material can be designed to build up inside the rotor against each of the shoe wall segments. The bed, which is made up of material that has been fed to the rotor, extends to a wear tip. The bed protects the shoe wall segment from wear.
Concerning the rock shelf anvil, it forms a near vertical wall of material upon which the accelerated material impacts. “Rock-on-rock” crushing reduces maintenance but can require up to 30 percent of material recirculation before meeting size requirements. Also, the rock shelf anvil absorbs energy that could otherwise be used for breaking, which may reduce efficiency. More RPM may be needed to achieve the same result as a solid metal anvil.
Good for medium abrasive materials, rock-on-rock configurations of either or both rotor and anvil may produce consistent material with low-wear cost and can handle wet but not sticky conditions. Reduction ratios from 2:1 to 5:1 can be expected. It’s widely used for quarried materials, such as sand and gravel.

Due to the many configurations of the VSI feed, rotor, anvil and open- or closed- system design; testing is the only way to ensure proper application of a VSI crusher.

### Summary
The VSI is one of the most versatile crushers available on the market today. Even with some limitations, like feed size and output capacity, VSI features have been and continue to be developed to maximize first-pass yields and lower operating costs. If you test your process on full-scale equipment before choosing your VSI, you won’t be disappointed.

## Watsontown Opens New Plant with New Horizontal Shaft Impactor from Stedman
_Reprinted from BRICK NEWS AUGUST 2001_
For Watsontown Brick, nestled in the foothills of the Appalachian Mountains in Watsontown, Pennsylvania, the decision to build a new plant was not made lightly. Owner Mike Fisher wanted to both increase production and meet the changing needs of architects and builders. Doing that meant building a new, bigger plant and purchasing additional kiln cars and equipment. Additional equipment included a Grand-Slam™ Impactor for use as a shale crusher, with capacities from 110-125 TPH. The [Grand-Slam TM Horizontal Shaft Impactor](https://www.stedman-machine.com/grand-slam-impactors.html) helped reduce operating costs and increase production.
_Photo, Watsontown Brick uses a Stedman Grand-SlamTM Model 4260 Impactor._
Fisher's family has been in the [brick industry](https://www.stedman-machine.com/brick-clay-ceramics.html) for decades. His grandfather became involved with Watsontown Brick in the 1930s. His father bought the plant during the 40s and Fisher took over the day-to-day operation of the plant in 1983.
Founded in 1908 by a group of investors, the company originally manufactured primarily 4"x4"x10" paving brick, which were used on neighboring city streets.
Today, 75 percent of the company's production is cored face brick used in building. Pavers make up the remaining 25 percent.
Watsontown's market area has also changed. In addition to the local area, the company now markets its brick throughout the northeastern United States, with approximately 50 percent of the company's product going to New York City and Boston. They also service distributors in Nebraska, Ohio, Illinois, Indiana, Michigan, Maryland, Virginia, Delaware, New York, Connecticut and Massachusetts.
To meet the changing market needs and his production goals, Fisher determined that automation was the answer. Fisher said, "The brick industry lends itself to automation. Producing brick is a time consuming process. Finding people to work in the plant can be difficult. Automation streamlines the process and allows us to increase production.
PIn addition, Fisher wanted to be able to diversify and create different types and sizes of brick. Planned changes, such as a higher temperature kiln with a capacity of 2100°F to 2200°F, would give the company the capability to branch out and produce different types and color of brick. "Architects like to be creative," he said, "We wanted to be able to meet the demand." Until this time, Watsontown Brick had been producing only red brick.
During the planning stages, one of Fisher's concerns was finding an impactor that could handle the increased capacity. Fisher said, "When we built the new plant we felt we wanted to get another Stedman Grand-SlamTM Impactor, one with a higher capacity for bigger volume. We were pounding the lower capacity machine. We knew we needed a bigger one. We lived with it in the older plant, but we didn't want to in the new one."
To meet the requirements of the new plant, Fisher selected a Stedman Grand-SlamTM 4260 with a capacity range of 110-125 TPH and an inlet opening of 21" high x 61" wide. Installed in the fall of 2000, the Stedman runs non-stop at the Watsontown plant.
_Photo, One operator on a raised platform can oversee several operations._
The shale comes from two deposits located just behind the plant. From one deposit the company mines regular shale. The other deposit holds a plastic yellow shale. As the deposits are worked, the company must rip and blast deeper in the pit where the shale is harder. An Eagle primary crusher processes the material as it comes from the mine, reducing the shale to 4 inches. A front-end loader piles the material in huge storage sheds. A feed material loader then feeds the material into two hopper boxes at the rate of 100 TPH.
From there, a vibrating scalping screen with 5/8" opening on top and a 10 mesh on the bottom deck moves the material to storage or to the grinding room. The 10 mesh material goes in to 90 ton capacity steel storage tanks. The oversize material is fed to the Stedman impactor in the grinding room. The impactor reduces a shale and clay mixture. Moisture content of the shale is dry to 10 percent. Bulk density is 90 lbs. per cu. ft. Feed size is minus 1-1/2". Product size is -10 to -12 mesh.
The material handled by the impactor is 80 percent shale, with 10 percent a combination of clay and shale and the rest clay. Watsontown uses its own supply of clay and imports, Ohio fire clay to add to the mixture. From the impactor, the shale runs through four finish screens. All product not sized to specification returns to the impactor.
On the first pass, the Stedman reduces the shale/clay mixture so that 60 to 65 percent of the product will pass finish size. The rest returns to the impactor for another pass. Reduction can take up to 3 trips.
In the plant, the impactor, clay working machine, the extruder, the kiln and all other production processes are monitored by a single person in an elevated control room in each area of the plant. This lets the operator keep an eye on the controls and watch over the processes below. The system is designed to automatically shut down if some portion of the system is not functioning properly.
In addition, the new plant is equipped with full dust control, which means employees do not need respirators or masks. The noise level is also low, so that employees do not need earplugs.
Scrubbers take care of sulfur emissions that may be given off during the firing process. The plant also recycles any damaged brick by running it back through the production process. Any slab that is cut off during the extrusion process is scooped up and put back into the pile to dry and be reground.
_Photo, Robots stack green brick on kiln cars._
The plant operates 365 days a year, 24 hours a day. Enough brick are extruded in five days to keep the kiln running day and night, seven days a week.
The cars are programmed to move automatically through the holding and firing process so there is no need for human monitoring. The company has two storage areas, one for the unfired brick and one for the fired brick. To keep pace with the demand, production runs one shift daily. Unloading and packaging runs two shifts.
Watsontown Brick now produces about 75 million brick a year, an increase of 40 million over the old plant and the Stedman impactor has met Fisher's expectations and helped reduce his operating cost.

### Agricultural Lime May be the Key
By Eric Marcotte,
AGRICULTURAL LIME, OR [AGLIME](https://www.stedman-machine.com/aggregate-crushing.html), is a soil conditioner most commonly produced from finely crushed limestone. It provides a source of calcium and magnesium for plants, increases the pH of acidic soil, enhances water penetration, and improves the uptake of nitrogen, phosphorus and potassium r NPK. For farmers, this means lower crop production costs, but for quarries with the proper chemistry for Aglime production, it equals another product to sell.
Reducing soil acidity reduces unfavorable conditions caused by iron, aluminum and manganese. It also increases the availability of critical plant nutrients (nitrogen, phosphorus, and potassium) by providing an environment that allows micro-organisms to break down organic matter, and it increases the effectiveness of herbicides. The Michigan State University's Extension Bulletin E-1566 states, "Aglime can return $5 to $10 for each dollar invested in lime. Raising soil pH from 5.7 to 6.5 in mineral soils may improve corn or soybean yields by 20 percent or more, and alfalfa yield by 35 percent or more."
When Aglime comes in contact with the acids in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidic H+ ions react with the carbon-ate (C03) to form carbon dioxide (CO2) and water (H20). The result is a soil that is less acidic (has a higher pH). Why does size matter for Aglime? The smaller the particle size, the higher the percentage is absorbed in the soil within the first year of application. Particles smaller than 50 mesh - 100 mesh are completely absorbed within the first year of application - 100-percent effective. Particles between the 10 mesh X 50 mesh sizes are 50-percent effective over a three-year period. Materials larger than 10 mesh are considered too large to dissolve within a three- to four- year time period. The decision of what mesh size to use depends on how rapidly the farmer wants the full value of Aglime to be realized.
### Aglime Materials, Chemical Composition, and Calcium Carbonate Equivalent (CCE)
The second major factor that determines Aglime quality is chemical composition. Chemical composition determines an Aglime material's amount of acid it can neutralize. Pure calcium carbonate (CaC03) has an acid neutralizing value of 100 percent. When an Aglime material is evaluated, it is compared to calcium carbonate, and its neutralizing value is called the Calcium Carbonate Equivalent (CCE) value or percent CCE.
To sell Aglime to different regions, review the state requirements for percentages passing the different mesh sizes and the calculation required to provide the required Calcium Carbonate Equivalent.
**Most U.S. states have unique specifications for Aglime.**

_The following states don't list sieve sizes: Arizona, Hawaii, New Mexico, North Dakota, Rhode Island, South Dakota, Texas, Utah and Wyoming. Colorado and Nevada have alkaline soil that requires the addition of acids to adjust soil pH._
## Types of crushing methods used for Aglime production.
The primary crushing method used is impact with [Cage Mills](https://www.stedman-machine.com/cage-mill-pulverizers.html), [Hammer Mills](https://www.stedman-machine.com/hammer-mill-crushers.html), and [Vertical Shaft Impactors (VSI)](https://www.stedman-machine.com/v-slam-impactors.html).
### Cage Mills
Final product size is controlled by pin spacing and cage speeds. Cage mills have lower maintenance than a hammer mill. HP/ton ratio is approximately 7:1 and produces a Particle Size Distribution (PSD) that passes most state specs without screening. Cage mills handle moisture well because there are no screens or grate bars.
### Hammer Mills
Final product size is typically controlled by grate bars or perforated screens, which can be high maintenance because of the many hammers and grate bars or screens to replace. The highest HP/ton ratio is approximately 10:1. It doesn't handle moisture well due to blinding of the screen/grates and it cannot handle uncrushable items.
### Vertical Shaft Impactors (VSI)
Final size is controlled by rotor speed, but a VSI can't grind fine enough to pass some state Aglime specs and requires screening after crushing. HP/ton ratio is approximately 3:1 with high throughput. Moisture can cause buildup problems.
## Where should I start?
Determining the chemistry of your material's Calcium Carbonate Equivalent (CCE) is the place to start. You will need to determine the amount of Aglime material required to equal one ton of pure calcium carbonate. For example; if your material is Dolomitic Limestone, with a CCE of 95, the rate per acre equivalent to Calcitic Limestone, with a CCE of 100, would be 1.05.
| |
| --- |
| Aglime Materials, Chemical Composition, and Calcium Carbonate Equivalent (CCE) |
| | | |
| --- | --- | --- |
| MATERIAL | COMPOSITION | CCE (%) |
| Calcium Carbonate | CaCO3 (pure) | 100 |
| Calcitic Limestone | CaCO3 | 80-100 |
| Dolomitic Limestone | CaCO3-MgCO3 | 95-108 |
| Burned or Quick Lime | Cao (calcium oxide) | 150-175 |
| Hydrated or Slacked Lime | Ca(OH)2 (calcium hydroxide) | 120-135 |
| Marl | CaCO3 | 70-90 |
| Ground Oyster Shells | CaCO3 | 90-100 |
| Cement Kiln Dusts | Ca Oxides | 40-100 |
| Power Plant Ashes | Ca Mg & K Oxides | 25-50 |
| Wood Ashes | Ca Mg & K Oxides | 40-50 |
| Gypsum | CaSO4 | None |
| Byproducts & Biosolids | Variable | Variable |
Testing your feed material is the next step and should determine the following: feed size (PSD), energy consumption (horsepower per ton per hour or kW per ton at the target PSD), wear metal estimate per ton of throughput and finished product particle size distribution.
In conclusion, the production of Ag lime can be achieved in many ways, and each operation will have its own set of specific requirements that influence final production. When deciding what crusher type is best for a specific operation, it is important to consider the following: local market conditions, state specifications, existing equipment and facilities, maintenance requirements, total power consumption and existing capacity, and auxiliary capital equipment.
Agronomists in many states can help evaluate the economics of soil chemistry and how Aglime can be used to reduce fertilizer use, improve crop yields and lower costs. Some states may subsidize the use of Aglime. Contact a local university extension to learn about the use and incentives in your region.

## Teamwork Helps Integrate Design, Manufacture and Installation of Size- Reduction Systems
_By Eric Marcotte, Inside Sales Manager, Stedman Machine Company_
[Designing](https://www.stedman-machine.com/process-design.html) and deploying [size-reduction systems](https://www.stedman-machine.com/particle-size-reduction.html) takes experience. Many people can collect and install some of the pieces they feel are needed to create a working system, but experience with the interrelationships between components is harder to find. And to ensure safety and performance, crushing, screening, storage and handling systems need to be professionally engineered. A system is always more than just a collection of parts; they must work together whether it’s a properly designed chute or an elaborate processing plant.
Retrofitting new [crushers](https://www.stedman-machine.com/impact-crushers.html), conveyors, screens or other pieces of equipment is also not always an easy process. Even if drawings and specifications no longer exist, plant designers need to make sense of what is there and know what it takes to make new pieces fit in an existing puzzle. If continuing production during the upgrade is required, system bottlenecks will need to be prevented. For example, raw material or finished product stockpiles may be required to keep downtime to a minimum. Also, access and space requirements need to be confirmed and double-checked.
### First - Assemble a Team
Engineering and expertise in a variety of areas are required to develop size reduction systems, including: crushing, screening, structures, conveyors, chutes, hoppers, [dust collection](https://www.stedman-machine.com/dust-collection.html) and storage, whether for a small equipment retrofit or a large turnkey facility. CAD and process design software applications are must have. Limit multiple layers of personnel. Work directly with the engineers and personnel to select the equipment and design the system. [Project management](https://www.stedman-machine.com/project-management-and-installation.html), [installation](https://www.stedman-machine.com/project-management-and-installation.html), scheduling and tracking experience will be needed. Be sure supervisors and installers are MSHA trained and have experience in fieldwork.
### Second - Process Design
While most projects present new challenges, a widely experienced team will bring in ideas from other industries. Typical projects involve the following processes and types of equipment.
- Load out and material receiving
This can be a feed hopper with an apron feeder, belt feeder, vibratory or screw feeder, truck dump or railcar unloading system.
- Bulk material transportation
Designing, building or procuring belt conveyors, stackers, apron conveyors, screw conveyors, and pneumatic handling conveyors.
- Crushing
Crushing is the basic building block of a size-reduction system. Experience with a large range of crushing equipment offers many solutions. Properly feeding material into the crusher greatly increases its efficiency, contributes to even wear and maximizes wear metal costs.
- Bulk material storage
Specifying, providing and installing a range of silos, hoppers or other bulk storage solutions.
- Screening
Experience with many screening manufacturers to include the right screening solution into the system.
- Dust Collection
Including the proper dust collector and dust collection system is a key component to allow a crushing system to work properly. Experience with many dust collection vendors will facilitate properly sizing, connecting and installing the best dust-collection system solution.
- Controls and Electrical Components
To make sure that all components of a system work together, work with control system engineers, panel builders and electrical contractors to create a working, integrated system.
- Buildings, Foundations and Structure
Design, procurement and specifications for buildings, foundations and structures for the equipment supplied on any system.

[](https://www.stedman-machine.com/assets/images/buckets/teamwork-2.jpg)
### Third - How to Do It
Every project has a different set of circumstances that are unique to it. Try to follow a simple checklist to ensure the best possible solutions to the problems.
- Initial project team meeting.
- Crusher and screening testing as required.
- Define required scope for the system.
- Create preliminary concepts and drawings.
- Review with operators and supervisors.
- After receiving feedback, fine-tune the drawings, concepts and put forth a detailed proposal.
- Set up kick off meetings as required.
- Proceed with the purchase of major components.
- Proceed with a detailed system arrangement.
- Detail major assemblies.
- Assemblies put out for detail drawing creation.
- Drawings are self-checked and then crosschecked for accuracy.
- Assemblies are re-entered into system layout from detail assemblies to verify fit.
- Approval drawings sent out as required.
- Vendor drawings checked and approved.
- Items checked as they are received.
- Work with vendors and shipping to verify shipment accuracy.
- Pictures are taken of all shipments for record purposes.
- Installation supervisor works with install crew to identify, locate and erect items as needed.
- As installation finish date nears, begin check of motor rotations, sensors etc.
- Final customer acceptance – formal reviews to finalize “punch list,” follow up items and document the system is performing as specified.
### Example - Typical Quarry Expansion
A [limestone](https://www.stedman-machine.com/aggregate-crushing.html) quarry running since the 1950s and producing 500,000 tons per year wanted to increase yearly production capacity up to 1.5 million tons with a new automated plant. The new design needed to have the capability to stockpile hundreds of thousands of tons of finished product. The focus was on creating a state-of-the-art plant with designed-in flexibility to do different product sizing. The automated plant needed to have the ability to run production all day as well as to be able to change the product sizes within 10 minutes.
The design and fabrication of a new plant may take up to two years to complete as each idea is considered and "wish lists" are sorted out. You don’t want to come back and say we should have done this or done that. Get the very best of everything you can get into the plant for longevity. The project will include numerous conveyors, sensors, controls, vibrating screens, feeders and other equipment.
Installed electronics and control systems feed a programmable logic controller. Each conveyor at the plant is equipped with terminal strips that are all wired to communicate information to one main processor, bringing all of the information together in one place to make it easy to operate.
All of the feeders and conveyors are monitored to collect all of the information required to operate the plant. With the ability to monitor the speed of the conveyors and feeders, the quarry can keep an eye on production and troubleshoot maintenance issues. The reason for having an automated control system is that if something goes wrong on one of the conveyors, you’ll see it fast enough to prevent a catastrophe that might require digging out a conveyor. If something does go wrong, the computer can take over and begin dropping conveyors, discharging material and shut the feeder down.
Since the quarry can now monitor the conveyors moving, the speeds and the tons per hour, limitations can be set to help catch problems before they become too serious. If something is going wrong, say conveyor 2A is slowing down, you can put limits on how much you want to allow it to slow down before the feeder is paused and then limit how long that feeder stays paused.
In the end, the quarry was able to more than double their production capacity with the help of the automated plant. The plant was built, delivered and installed as planned with no problems. This is an ideal situation if a quarry is sitting on huge reserves of limestone and plans to operate the crushing plant well into the future.
Projects such as this are successful when the customer’s needs are defined and understood, and the project team – including the customer and all supplier partners work to accomplish the project goals.

Most Common Problems With Size Reduction Equipment
# Most Common Problems With Size Reduction Equipment
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Most Common Problems & Answers
**Q: What are some typical problems with size reduction equipment, and how can they be addressed?**
**A: Chris Nawalaniec, Stedman Machine Company, says:**
The following are some typical size reduction equipment problems and some advice to address these issues.
### Problem: Wear part costs are too high?
- Turn the faces of your wear parts or exchange these issues with those from other areas of the equipment that don't wear as much.
- Run crushing tests with your material on various equipment types. Testing also yields important information about the size reduction process such as particle size distribution before and after crushing, moisture content (which changes during crushing, affecting the material's handling characteristics), power consumption, and estimated wear cost (in terms of how frequently metal parts must be replaced). The test will also determine how well the equipment handles your material's other characteristics, such as friability, abrasiveness, plasticity, and heat sensitivity.
- Look for unusual wear patterns on parts to detect feed or discharge problems that can be addressed.
### Problem: Energy costs are too high?
- Properly feed the crusher. The feed may not be evenly distributed across the crusher face, or it may not be at the proper choke amount. The feed may not be entering the crusher at the proper angle as it shouldn't initially hit the rotor directly.
- Try using one machine that can do the entire size reduction job, which will save money and improve your process. Cage mill crushers can achieve up to 40-to-1 size reduction ratios.
### Problem: Labor costs are too high?
- You may be spending too much time unclogging the machine. Moisture can cause material buildup, which can clog the crusher and require long hours of maintenance to clear the crusher. Air cannons can release material clogging impact aprons and impact anvils. If your feed entry chute is clogging because of sticky material, heaters can be used to cause material to slide off the feed entry chute.
### Problem: Production levels are too low?
- You may consider installing a screener prior to the crusher to remove on-size particles from the raw material. This reduces wear on the crusher and minimizes the number of times the material is handled, resulting in a higher profit per ton of material.
- Impactors can offer a higher production rate without the need for screens if you can afford to have some oversize product.
### Problem: Equipment is high-maintenance?
- Hammermills may require more maintenance than you prefer. Substituting an impactor is a lower-maintenance choice.
- Also, a cage mill may be able to reduce your two-stage process to a single-stage size reduction process.
### Problem: Equipment isn't used enough?
- Consider toll processing. Most size reduction equipment suppliers also offer toll crushing services for a fee, which can be valuable in the right circumstances. For instance, you may need toll crushing to help develop a new product or improve or develop a process before investing in new equipment. You may also require toll crushing to meet an intermittent need (such as once per quarter) for crushed material or to obtain crushed material if your company has limited capital for purchasing size reduction equipment.
### Problem: Equipment is too dangerous?
- Explosive materials (very fine airborne dust particles) are often the cause for safety concerns. Introducing water after crushing can offer a solution. In extreme cases with extremely explosive material, water may need to be introduced before crushing but that will increase wear.
### Problem: Equipment service is poor?
- A well-maintained crusher will last 20 to 30 years, and your supplier should provide assistance throughout its lifetime. You should have documentation to refer to on startup, commissioning, and training and keep recommended spare parts in stock.
- Make sure your equipment supplier offers the continuing service you need. Around-the-clock service can be invaluable for emergencies and to address safety concerns.
### Problem: Equipment costs are too high?
- Consider how the crusher affects the process's total energy requirement. For instance, can the crusher you're using yield product with a narrower size range that requires less downstream processing?
- Cost per ton factors into your product's value. Gold slag obviously requires reclamation but wear part costs can be a 100 times more than for a limestone application.
Selecting the proper size reduction method is part science and part experience, and troubleshooting equipment and process problems can be just as difficult. Maintaining your relationship with the supplier over the long-term will also help you stay abreast of new size reduction technology. This will help your operators and maintenance workers evaluate whether updating your equipment or process can improve your product quality, increase the production rate, or reduce your operating costs.

Properly Milling Limestone
# Properly Milling Limestone

### Test center helps a mining company select the correct mill for a new installation.
When it comes to [size reduction](https://www.stedman-machine.com/particle-size-reduction.html), having the correct mill is crucial to ensure a high-quality end product. While designing a new line to process [agricultural](https://www.stedman-machine.com/agricultural.html) lime and feed supplements, Wake Stone Corp., a mining company based in Knightdale, NC, which specializes in construction and agricultural materials, needed to find a mill able to provide a consistent particle size and quality. The new mill was needed at Wake Stone's North Myrtle Beach plant, which also has a limestone [aggregate crushing](https://www.stedman-machine.com/aggregate-crushing.html) and screening operation.
Wake Stone's current facility was designed and constructed in 2001 and an agricultural plant was added in 2011, but the company has been operating in North Carolina since 1970. This longevity has been achieved with the philosophy of doing things the right way the first time when designing and building a plant in order to save money down the road, as well as having a spare part for many critical components in the plant. This mindset meant Wake Stone needed to thoroughly test and evaluate a number of different milling options before purchasing one.
To find a mill that would fit its goals and material, Wake Stone turned to Stedman, a size reduction equipment manufacturer based in Aurora, IN. The supplier has two [testing and toll crushing facilities](https://www.stedman-machine.com/testing-facility.html) to evaluate customers' material and figure out which piece of equipment is best for each application.
"Working with Stedman's test facility was a great experience," says Jared Miedema, director of engineering for Wake Stone. "Their testing technician helped us with a variety of mill feed gradations, giving us insight as to which mill would work the best."
Most of the size reduction equipment testing takes place in the supplier's main test facility, while most toll crushing is done at another, recently expanded test facility, although both facilities are used for various testing and toll crushing services. The recently expanded testing and toll processing facility has two [horizontal-shaft impactors](https://www.stedman-machine.com/mega-slam-impactors.html) and other full-size equipment including [cage mills](https://www.stedman-machine.com/cage-mill-pulverizers.html), [vertical shaft impactors](https://www.stedman-machine.com/v-slam-impactors.html), [hammer mills](https://www.stedman-machine.com/hammer-mill-crushers.html), and [lump breakers](https://www.stedman-machine.com/lump-breakers.html). Open- and closed-circuit and air swept systems can be used for prepurchase testing, process development, and toll processing.
Each machine can test the client's material at different speeds to ensure the right particle size reduction requirements can be met while keeping up with production demands. The supplier also performs material tests, including moisture content analysis, particle size distribution analysis, bulk density analysis, abrasion tests, and more to ensure the right equipment is selected for the material.
Wake Stone needed a new mill to use as the tertiary crusher in the North Myrtle Beach plant. The tertiary size reduction step occurs after the material has already run through the [primary](https://www.stedman-machine.com/mega-slam-impactors.html) and [secondary size reduction](https://www.stedman-machine.com/grand-slam-impactors.html) steps in the aggregate plant, meaning the material needed a final run through a mill to achieve a consistent gradation before being sent through a moisture mixing station.
### Finding the right solution
After testing several different mills at the supplier's testing facility, Wake Stone found that a H54 cage mill would handle the material and ensure only particles of a specified size would leave the process. A multi row cage mill consists of a fabricated steel housing that encloses the wheel-shaped cages. Each cage includes a steel plate fitted with equally spaced pins arranged in a row around the cage perimeter.
At Wake Stone's new [installation](https://www.stedman-machine.com/installations.html), the cage is placed directly after a vibratory screener, and material is fed into the machine off the top deck. As material flows through the cage mill's intake hopper and chute into the innermost cage's center, the adjacent cages rotate in the opposite direction to propel particles. The particles' impact velocity can be adjusted by increasing or decreasing the operating speed of the cages. The cage mill can fully process the material in a single pass when running at full speed.
"Once we settled on the H54 model, we also tested different speed configurations, which were very helpful," Miedema says.
After installation, Wake Stone found that the cage was wearing unevenly. To counteract the uneven wear, the company installed a slide chute on the feed end to force material farther into the mill, facilitating proper distribution and extending the life of the sleeves. Wake Stone also installed a new hub and plug assembly so that the single unit centers the cages on the shaft to eliminate any misalignment, keeping the cages centered.
"We've had ongoing support from Stedman throughout the life of this crusher," Miedema says. "They had a very experienced technician help us during our balancing issues, which proved beneficial."

What is a Chain Mill? - Chain Mill Crusher Overview
# What is a Chain Mill? - Chain Mill Crusher Overview
[Contact Us](https://www.stedman-machine.com/contact-us.html)
## Chain Mill Crusher Overview
You’re crushing it, but why bring the proverbial sledgehammer when a simpler machine will do? [Chain mills](https://www.stedman-machine.com/chain-mill-crushers.html) represent a cost-effective crushing solution for reducing a wide variety of materials.
### What is a Chain Mill?
Chain mills are designed for rapid, uniform, and economical reduction, in open or closed circuit, of loosely bound agglomerates and other sticky materials with a minimum of clogging. These machines are particularly effective as a [fertilizer](https://www.stedman-machine.com/fertilizer.html) crusher since the chain mill is designed to break up lumps in superphosphate, triple-superphosphate, granular, and conventional fertilizer tailings. You can also find chain mills in the production of animal bedding, sawdust, and other clumping materials.
### How does a chain mill work?
A series of chain links, rotated at high velocity reduce particle size by impacting the material. For most friable materials, the chain mill produces a consistent discharge particle size distribution largely independent of the feed particle size distribution. It produces few fines or finely broken material. This mill easily handles material that tends to cake or clog. The efficiency of the mill means it requires less recirculation in closed-loop configuration to meet size reduction requirements.
### Design
Efficiency comes from the correct rotor velocity and the configuration of the rotor chains. The proper chain spacing allows the material to fall lower into the path of the chain links before being impacted. A counter-rotating dual-rotor configuration causes multiple impacts of the material to accelerate it as it moves down through the mill. The open interior design allows foreign materials to pass easily through the mill.
The mill is simply constructed of welded plate steel and bolted assembly, yet it is rugged so that it will maintain long use with little adjustment, repairs, or wear part replacement. Chain mill rotors are balanced, and little vibration of the chain mill housing is noticeable during normal operating conditions.
No screen is required to maintain the material in the grinding zone until it is reduced to a specified size. The elimination of a screen permits reduction of many materials, which would clog a screen. In the fertilizer industry, it’s not practical to use grates or sizing screens because of the choking and clogging characteristics of the material.
### Configurations
The simplest single rotor design has its shaft supported on both sides of the housing by bearing supports. A chain curtain at the impact end has controlled swinging action. Some single rotor chain mills feature a coarse vertical screen at the impact end instead of a chain curtain. Keep in mind, the screen or chain curtain isn’t to limit top size material as in a hammer mill; it acts as an anvil.
In the double counter-rotating design, as the one illustrated, the shafts are supported on both sides as well. The two independent chain rotors rotate in opposite directions forcing material quickly through the mill
Cantilever designs place all of the mechanical parts on one side of the crusher. There is also a single rotor, vertical shaft cantilevered design that feeds material from the top. It falls through the mill as the rotating chains crush it.
### Capacity
The chain mill comes in just about any size required and can handle from 5 to over 600 tons of material per hour, with virtually no possibility of plugging or clogging. Speeds of up to 1500 RPM are typical, depending on fineness required. Rotor widths range from 15 to 42 in., according to the capacity required, and single or double 7.5- to 120-hp electric motors are typical.
### Operation and Maintenance
The chain mill is forgiving of normal wear and tear. It’s relatively inexpensive to maintain, needing only routine replacement of chain links or liner material. Large doors on the chain mill and the open interior design allow easy access to all parts of the mill for [inspection](https://www.stedman-machine.com/inspection.html) and [maintenance](https://www.stedman-machine.com/maintenance.html). Chain links and wear-resistant impact liners can be inspected without having to disassemble any part of the chain mill.
### Why choose chain mills?
For a low-cost, highly efficient crusher for soft, clumping, or agglomerate material, the chain mill can’t be beaten.

## A New Size-Reduction Impactor has Significantly Reduced Downtime and Increased Production Efficiency for Robinson Brick Company
[Grand-Slam™](https://www.stedman-machine.com/grand-slam-impactors.html) size-reduction impact crusher replaces old primary clay crusher and two hammer mills for an increased grinding efficiency of 20% and replacement part savings of thousands of dollars.
_By Dennis Gilmour, President, Stedman Machine Company_
Robinson Brick Co., Denver, Colorado. was formed in 1880 and is the oldest and largest brick manufacturer in Colorado. Operating with approximately 250 employees, the company manufactures 100 million bricks annually, as well as an extensive line of natural rock and thin veneer brick products marketed under such trade names as Robinson Rock™ and Old Brick Originals™. Over the years, the company has established a reputation for being the first in the industry to try new methods and new equipment. In the '40s, it installed one of the West's first tunnel kilns. In 1959, it opened a state-of-the-art showroom, also an industry first. Robinson also installed the first robotic brick setting machine in the U.S., and in the fall of 1998, it became the first facing brick manufacturer in North America to be registered under the ISO 9001 standard.
Robinson is also one of the most technologically advanced manufacturing plants in the industry. It continually upgrades its production operation, paying careful attention to quality. If part of the company's system is not keeping pace with production, the company quickly addresses the issue. About three years ago, the primary crusher and the two hammer mills the company used to process its clay began slowing production and causing daily downtime. The hammer mills were high-maintenance and could not handle the frequent swings in moisture content. Production was often reduced to a crawl when the hammer mills encountered wet chunks of clay.
Maintenance personnel were spending over five hours each night working on the hammer mills, not to mention the additional time for the crusher and associated feed belts. "We were constantly replacing the tips and shanks on the hammer mills and balancing them. They had to be extremely well balanced to handle the clay," said Tony Fabrizio, Robinson Brick director of manufacturing and research and development. "Between the primary crusher and the two hammer mills, replacement parts were costing us up to $20,000 a month, and the man-hours to keep the crusher and hammer mills going were too high. The inefficiency was not acceptable." Along with Plant Manager Mike Gomez, Fabrizio began searching for an alternative.
## Easy Operation and Maintenance
In the fall of 2000, Robinson purchased a Stedman [Grand-SlamTM 4860 impact crusher](https://www.stedman-machine.com/grand-slam-impactors.html), GS4860AR/HC-T-X, with a capacity range of 100-150 tons per hour (tph). "We chose the Stedman because it was the most straightforward," Fabrizio said. "It was easy to use and maintain, and was also cost-effective."
The new size-reduction impactor replaced both the primary jaw crusher and the two hammer mills that had functioned as secondary and tertiary crushers, as well as a pan grinder. During the initial reduction or first stage, the breaker bars on the impactor impel material against the primary apron. During the second stage, the reduced material passes through to the second apron for final reduction. Both aprons allow precise gap adjustment to ensure properly sized product for the specific application.
The impactor provides up to a 30:1 material reduction ratio for more properly sized material on the first pass through. An open discharge on the impactor eliminates any clogging or buildup of material exiting the crushing chamber.The size-reduction impactor also increases crushing capacity and throughput so that the circuit runs more efficiently. It can handle a wide variety of materials, ranging from wet and tacky to hard and abrasive. Maintenance on the impactor is designed to be easy. The rotor breaker bars can be reversed or removed quickly, often completed in two hours and helping to minimize downtime. Additionally, the front and rear housing on the impactor is hinged and, when opened, provides unobstructed access to all areas of the crushing chamber and rotor. The rotor lock table allows breaker bars to be rotated or replaced by one person with minimum of downtime.
## Customized Design
Another benefit of the new impactor was that it was built to Robinson's specifications. One of the options Robinson chose was an air cannon with a timer. The air cannon periodically discharges a blast of air into the crushing area to dislodge dry material buildup, thereby reducing cross-color contamination and keeping buildup to a minimum. To further minimize buildup, Robinson also had heaters installed on the aprons and nose liner of the housing.
The intake hood and the crusher support structure were also customized for Robinson to simplify the mounting of the Grand-SlamTM Impactor. The impactor was equipped with a proximity switch on the front-hinged housing for disengaging the crusher drive motor if the crusher should be opened while the rotor is turning. To give the plant additional control over the product, Robinson Brick outfitted the new impactor with its own variable frequency drive for the 300-hp crusher motor. The drive allows the speed of the mill to be increased or decreased to maintain the desired end product, and also helps when the moisture content is higher than normal and greater speeds are required.
Feed hoppers meter the material into a Grizzly feeder and directly into the new impactor. Feed sizes coming into the impactor range from loose dirt to grapefruit-sized clay. What emerges is clay that ranges from one-half inch to particles as fine as powder. The impactor processes a mixture of 100% clay and grog at the rate of 70 tph. With the old system, the average was 65 tph. It operates 11 to 12 hours a day and handles two feed streams,the clay feed from the Grizzly and the return feed. Only about 10 to 15% are returns, impressive since past performance realized a much larger return rate of 20-25%.
As the new impactor was being delivered, an accident occurred just a mile from Robinson Brick and the impactor was damaged so badly that it could not be installed. Robinson had prepared for the installation and was ready to shut down the plant. Stedman worked overtime to build a new impactor for Robinson. Within six weeks, another impactor was constructed and ready to be installed. "Stedman did an excellent job for us. They took care of us, and that is what matters," Fabrizio said.
## Increased Efficiency
Robinson is also pleased with the overall service it has received from Stedman. "Whenever we've needed assistance Stedman has been right there. The Stedman guys know what they are doing, and we can get a hold of them during off hours and on the weekend," Fabrizio said. Overall, the company is very satisfied with its selection. "We are very pleased with the Stedman impactor. It was the right choice. It has eliminated grinding downtime in a big way," said Fabrizio. Gomez adds, "For example, our nightshift maintenance time was previously 6-8 hours each evening-now it is typically 3 hours per night. Our overall down time on this line, a combination of nightshift maintenance and operating time lost during the day, was 10 to 12 hours daily, now it is only 3 hours in a 24 hour day, and that's incredible. And our monthly part replacement cost has gone from $18,000-$20,000 \[across both pieces of equipment\] to only $6000." Bob Jaster, president/COO of Robinson Brick agreed. "\[The new impactor\] has effectively increased grinding efficiency by 20%. I am really happy we bought it," he said.
