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.

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...
