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.

A cement mill is the equipment that used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media normally steel balls.

Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.

Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).

Closed-circuit grinding is used to remove fines from the milling system, so that the mill can function with a feed that is optimally coarse for its grinding action. In early grinding, both for cement and rawmix, sieves were originally used as the "separator".
