How to Calculate Grinding Media in Ball Mill? Generally, steel balls must not fill more than 35% of the ball mill. The size selection of grinding balls can be calculated using the following formula: Dm <= 6 (log dk) * d^0.5. Here, Dm = the diameter in mm of a single ball. d = the diameter in mm of the biggest ore piece ore in the mill.
