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.
