Then, cooled clinker ground in a ball mill. For the prevention of flash-setting of the cement 3 to 5 % of gypsum is added. Ball mill is a hardened steel ball that has different chambers that charged in sequence forward. The particles are crushed into the required fineness level. And particles are separated by air currents and taken to storage.

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.
