ball mills power and capacity

  • ball mills power and capacity anlaufstelle-lf

    Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho private communications).

  • AMIT 135: Lesson 7 Ball Mills & Circuits Mining 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 Ï b LD 2.5 where k is a proportionality constant.
