    27/04/2019 · The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. 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.

    01/09/2013 · Further, the ball size distribution in the mill is not a simple parameter that can be controlled directly, as it depends on the makeup ball charge and wear rate. Therefore, the industrial practice of determining the makeup ball sizes comes down to experience. However, there is a great deal of information that describes the variation of the grinding kinetics with the ball size and the ball ...
