In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53.

At most manufacturing plants the ball mill is used to grind the clinker and, since the production rate is directly related to the amount of electrical energy supplied, the power of the electric motor used to turn the mill is a first-order measure of the output achieved. Mills vary in their power input from as little as 200 kW up to 10000 kW.
