The prediction of power draw in wet tumbling mills

Data were collected from a wide range of wet industrial grinding mills to calibrate and verify the model. In total 76 data sets were generated covering the power draws of ball, SAG and AG mills in the range 7 - 7900 kW. All three models were found to predict the power draw of the mills in the data base with a high degree of accuracy.
