  • Charge behaviour and power consumption in ball mills

    01/08/2001· Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW. The actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 1–5%. Significant financial and environmental benefits can be obtained by improving this efficiency even slightly.

  • Ball Mills an overview ScienceDirect Topics

    A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.
