How it Works: Crushers, Grinding Mills and Pulverizers

Rock crusher. Material is reduced by crushers and grinders by fracturing, which takes place when the material is put under stress by the moving parts of the crushing or grinding equipment. Forces applied during the process may be compressive, shear or impact. The material fractures when the internal strain levels reach a critical level.
