Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

Ball Mill  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%).
