Raw Mills Critical Speed Cement

Cement mill Wikipedia

A cement mill (or finish mill in North American usage) Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The cement mills on a cement plant are usually sized for a clinker consumption

Ball Mill Critical Speed & Working Principle

19-6-2015· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. At least in terms of effective charge motion, then, there is no justification for resorting to lower mill critical speeds at larger mill
