Live ChatIt 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 b LD 2.5 where k is a proportionality constant.
