Aug 01, 2001· Typical power consumption for a5-m diameter by 7-m-long ballmill is between2.5 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.
