get price### Charge behaviour and power consumption in ball mills

The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.

get price### Charge behaviour and power consumption in ball mills

Aug 01, 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.
