Cement manufacturing brief description of a cement mill

Cement manufacturing brief description of a cement mill

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different size grinding media.
