### Charge behaviour and power consumption in ball

2001-8-1 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%.

More### Charge behaviour and power consumption in ball

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.

2017-2-20 The power consumption of the ball mill was monitored for two months, and the data is shown in the histogram in Figure 2c. It can be seen that the power consumption for each shift varied between 250 and 350 kWh. The data-set is negatively skewed, and the average power consumption for each shift during this period was 294 kWh.

In general these equations are used to predict power consumption as a function of mill size, level and density of the internal charge and % of critical speed. Almost none of these equations (with the notable exception of the Morrell’s model) consider explicitly the effect that the feed particle size has on the mill performance, particularly on the power and on the specific energy consumption of the mill.
