Interactions between Slurry Density and Grinding Media Size

The mill feed size distribution can also be adjusted but this implies changing the upstream processes which transposes the optimization process to another level Modification to grinding media shape is a possible avenue (Cooper et al 1994) but it remains that slurry density and grinding media size are probably the most frequently considered variables for the optimization of a ball mill
