The summary of these results are given in Table 1. The circuit capacity for the production of −48 mesh material was 33% higher for the high circulating load of 240% in comparison to the low circulating load of 40%. At the same time, the amount of fines (−200 mesh) was 2% lower for the high circulating load (although increased by 2% at 111% ...

Ball Mill Design/Power Calculation
The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.
