Apr 27, 2019  The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected.
