Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, 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 off or recycled, or to reduce the size of the solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
