Cement - cement clinker grinding product obtained by firing the starting raw material components.Fineness of grinding affects the quality and technological characteristics of the cement.
Clinker in cement plants often produce in a ball mill.This mill is a rotary drum at a certain speed, the inner surface of which is ribbed steel armored plates or rubber.
30-40% of the mill volume is filled with grinding media - steel balls with a diameter from 100 mm to 15 mm.For example, in a mill diameter of 2.0 m and a length of 10.5 m 32.0 tons more balls.
The drum rotates balls trapped ribbed slabs walls rising to a certain height, and falling, comminuted granules clinker coming into the mill a continuous stream.
Clinker grinding and turning slowly in cement, is moved from the mill feed end to the discharge.
