contact usComminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth''s crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...
contact usA 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.
contact us· When selecting the crusher, the type, hardness, inlet and outlet particle size, and output and construction site of the crushed material should be fully considered.. 1.
