Ghosh et al. investigated the nanonization of a model drug, NVS-102, using a planetary mill. They observed that the average particle size exceeded 1100 nm at 150 rpm, but it reduced to 300 nm when milled at 400 rpm, with other parameters constant [62].Effective size reduction is attributed to the frictional and impact forces acting in …

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
