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.

Handbook of Machining with Grinding Wheels

Grinding, once considered primarily a finishing operation involving low rates of removal, has evolved as a major competi-tor to cutting, as the term "abrasive machining" suggests. This is what Milton Shaw, the man who is considered the great pioneer and father of American grinding, said about 10 years ago.
