The proposed method provides a new approach of ball mill load forecasting. Improved EWT’s refined composite multi-scale dispersion entropy Improved EWT EWT is a time-frequency analysis method to extract sig-nificant modes of signals.
constant ball load of 28%. In the pilot scale experiments, the Magotteaux ball mill at Frank Concentrator was equipped with a Sensomag sensor for measuring the toe and shoulder angles of the slurry and ball load based on the principle of conductance and induction, respectively. The mill was configured to operate as a RoM ball mill.
