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.

The working principle of vertical roller mills is relatively simple. In a rotating drum, grinding media (steel balls or ceramic beads) are fed through the mill's inlet, and the particles are ground into smaller sizes by the mechanical forces generated by the motion of the drum.
