TECHNICAL NOTES 8 GRINDING R. P. King
The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4 The speed of rotation of the mill influences the power draft through two effects: the value of N and the shift in the center of gravity with speed. The center of gravity first starts to shift to the left as the speed of rotation increases but

Ball Mills  an overview  ScienceDirect Topics
For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. In practice, the ball mill is run at just below this speed (70–80%).
