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.

Step 1 keep your mill clean. This may sound obvious but a fundamental part of mill care is cleaning the mill and this step is often neglected. If a mill is kept clean, then 'leaks and creaks' (such as grease leaking from bearing seals) will be identified earlier, cost less to repair, and fixed before major equipment failure.
