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 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

Ball mills are the classic among grinding systems: They are used in about 90 % of all installations worldwide. The ball mill impresses with its simple principle and low maintenance requirements: it is robust, durable and has a high operating reliability. By using a separator in the closed circuit, the efficiency can be additionally increased.
Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers.
