Crushing
These types of crushers scrub material between two hard surfaces to achieve reduction in size and shape. Particles are reduced by their contact with other particles or by their contact with a rigid face. Crushers that use the forces of attrition provide a high reduction ratio. They are best suited for friable, less abrasive materials.
