A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
The crushing action of roll crushers on rock is completely by compression. Learn how to size, feed, maintain and operate a small roll crusher.

Single vs. Double Roll Crushers. Choosing between a single roll crusher and double roll crusher depends upon the type of feed material, feed size, product size desired, and consistency of both feed and product. Both single and double roll crushers operate most efficiently with dry, friable materials.
Double roll crushers are used for both, primary and secondary crushing. They guarantee a strictly de-fined final grain size with a minimum of fine grains. THE FEED MATERIALS Raw materials, secondary materials and by-prod-ucts such as coke, sinter, coal, soft to medium-hard rock, ore, chalk, broken glass and similar products.

Figure 6: Typical single toggle jaw crusher schematic Double Roll and Low Speed Sizers. The double roll crushers have two high-speed, parallel, toothed rollers with a fixed gap between them. As the material passes through them, it is subjected to mostly compression forces and some impacting forces.
In conventional mining, double-roll crushers are sometimes referred to as "mineral sizers" since they reduce the size of the largest chunks without pulverizing the smaller particles. These types of crushers or sizers are commonly used in reducing the top-size of soft or sticky material, such as limestone or lignite (brown coal).
