The roll crusher consists of a pair of horizontal cylindrical manganese steel spring rolls (Fig. 13.14), which rotate in opposite directions. The falling feed material is squeezed and crushed between the rollers. The final product passes through the discharge point. This type of crusher is used in secondary or tertiary crushing applications.
A crusher is a machine designed to reduce large solid chunks of raw material into smaller chunks. Crushers are commonly classified by the degree to which they fragment not starting material with wares crushers not reducing it by much, intermediate cruiser fragmenting it much more significantly and grinders reducing it to a fine power.
