An Updated Data Set for Sag Mill Power Model Calibration - Sagmilling
The SAG mill model by proposed by Leonard Austin (1990) was largely based on modifications of earlier tumbling mill models by Hogg & Fuerstenau and F. Bond. The model is loosely structured as a kinetic and potential energy balance to describe the power draw of a mill charge. The power drawn from a cylindrical
