  • AMIT 135 Lesson 7 Ball Mills CircuitsMining Mill

    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 ρ b LD 2.5 where k is a proportionality constant.
