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, tertiary or quarternary rotor crusher depending on which processing stage the equipment is being utilized.
Types of Impact Crushers:
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 cement crusher, mineral crusher, 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.
Crusher Throughput Production
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.
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 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.

Other Crushers (Compression Crushers)
Roll crushers are a type of compression crusher mostly used in heavy-duty industrial/aggregate applications. Roll crushers were once very popular in the mining industry, where they were used to reduce excess rocks, ores, and other materials. A roll crusher uses two or more cylinders or drums which are connected to horizontal shafts that rotate in opposite directions pulling material through the crusher. The material you wish to grind or crush passes through the cylinders creating a finer and smaller product. The compression and opposite rotation of the two cylinders create the force and friction necessary to break the material passing through.
Stedman does not currently offer a roll crusher / jaw crusher.
Jaw Crushers are mainly used in mining applications for grinding and crushing ores and rocks, but are not limited to the mining industry. Using compression methods, jaw crushers can handle and reduce many large sized materials. The jaw crusher uses a stationary jaw plate and a moving jaw plate to create a unique “V” shape. As materials pass through the machine, the moving jaw compresses and pushes the material against the stationary plate. This considerable amount of force then crushes the material down to a desired size before it can pass through the bottom of the Jaw Crusher.
