The effect of ball size on mill performance
This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2. The variation of a with ball diameter was found to be of the form a = k 2 /d 1.5. Both k 1 and k 2 vary with mill diameter, and simple power laws have been assumed, k 1 ∝ D 0.1, k 2 ∝ D 0.6.

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.
