Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand 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.

CRUSHING SCREENING

Unlike other types of impact crushers, vertical shaft impact crushers (VSI) are designed with a unique rock-on-rock crushing principle, which significantly reduces the wear costs while offering superior cubical shape for the best quality fine aggregate produc-tion.
