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%.

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.

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.

Scale‐up of power consumption in agitated ball mills

Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.
