in which the particles of the ore/mineral were subjected to milling by a spherical ball before the leaching/dissolution process. For the MA hydrometallurgical process, the key parameters for the mechanical device are the rotating speed (˜); diameter (d) of the milling/grinding ball; and its weight (M). The developed theoretical equation wasThe balls to powder ratio (BPR) and powder type were investigated in relation to the particle size. The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is 10.13%.

Process engineering with planetary ball mills RSC Publishing
Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be assessed for each individual system. The present review focuses on the insight into several parameters like properties of grinding balls, the filling ratio or revolution speed.The optimum conditions calculated by optimization were as follows: 58 rpm for as and 38.5 min for rt. The new working conditions identified for the ball mill considered enabled to rise output from 109 kg/h to 156 kg/h, with a 43% increase in productivity.
