## 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.

## ball mill power consumption - klimaatwebsite.be

Such mills are usually called pebble mills, but the working principle is the same as for ball mills As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is correspondingly smaller than for a ball mill , The specific power consumption is therefore less than for.
