Modeling of power consumption of ball mill

The possibility of predicting energy consumption for ball mill concentrator when implementing intelligent forecasting system. Compiled model to determine the power consumption of the electric

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.
