Mill Power And Grinding Capacity Examples

It is generally accepted that practical mill power PM is a function of mill capacity and diameter ieP M Mill Constant Mill Diameter n where n 03 to 05 It is evident that mill power is a function of the height at which the media is lifted and the density of the media ie PM K b LD 25 where k is a proportionality constant
