Crusher

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.
