Rock & Aggregate Crushers

rock crushers

Many different industries have a solid foundation rooted in aggregates. Recognizing the extensive use of these aggregates motivates us to continuously create and improve our rock crushing equipment to help you increase production, decrease maintenance and improve the overall efficiency of your operation. When it comes to quality and efficiency, our rock crushers are perfect for the job.

Choosing The Right Aggregate Crushing Equipment

Primary crushers are first in a typical size reduction operation. Primaries like our Mega-Slam™ horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes. The Grand-Slam™ 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 or coarse, medium-fine, or fine grinding cage mill.

Rock & Aggregate Crushing Equipment

Limestone, sand, and gravel are used for building and public works projects.  These materials are key ingredients in cement and asphalt 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. Available with capacities as low as 5 TPH up to 100 TPH, the 4-Row Cage Mill produces consistent product quality.

Limestone Quarry Increases Production Capacity to 1.5 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.

There’s no reason to guess what method will meet your needs.
The Stedman Testing and Toll Processing Facility is the place to test your material in our full size equipment. If it can be crushed, ground, pulverized or mixed, chances are we’ve done it. We have more than 10,000 test reports to help get you to the best solution quickly.
