PROCESS TRAINING for operators of Vertical RAW Mills
During heat up there should be a sufficient air flow through the mill to force the heat transfer to the grinding part – forced convection. A sufficient air flow will result in a mill differential pressure of> 5mbar. The duration of heating should be at least until the temperatures after mill and after bag filter reach 85° C.

Cement grinding Vertical roller mills VS 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.
