critical speed in grinding mill

High Speed Grinding Mill

20-6-2015· 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
