Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2.4 m/s.

Design aspects of large ball mills. - Free Online Library

The design of ball mill drives is, in many ways, more difficult than for AG and SAG units. This stems from the fact that the ball mill is generally smaller in diameter, so that the notional tangential force at the shell is higher for a given power input (although this effect is somewhat offset by the ball mill's higher rotational speed).
