The minimum speed at which centrifuging occurs is called the critical speed of the mill, and under these conditions, centrifugal force will be exactly balanced by the weight of the ball. Little or no grinding takes place when a mill is centrifuging. If the mill is to operate practically, the operating speed must be less than the critical speed.
