THE OPTIMAL BALL DIAMETER IN A MILL
The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter ball mill loading milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Ball Millan 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 ).
