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.
