Analysis of ball mill grinding operation using mill

2014-3-1 An analysis of the published experimental data on variation of the mill power with mill speed shows that in the range 55–70% critical speed the torque corresponding to the net power drawn by the mill either remains practically constant,or it increases gradually with the mill speed by about 8% . These data can be utilized for evaluating the energy efficiency of the grinding operation.
