Cement grinding Vertical roller mills versus ball mills
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.

Formula to calculate grinding media wear rate for cement mill
From this experiment we got following result: 0.002389 MWh/t. Now using standard formula we can calculate grinding media wear rate: Wear Rate (g/kWh) = 0.042 * H * D^0.67 * η. H=Hardness in Mohs Scale. D=Diameter of Ball (mm) η=Efficiency Factor (decimal) Factors affecting wear rate of grinding media.
