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 firstorder measure of the output achieved. Mills vary in their power input from as little as 200 kW up to 10000 kW.

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
