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 of or recycled or to reduce the size of a solid mix of raw materials as in rock ore so that pieces of different composition can be differentiated
