Sag mills in the gold and copper operations would vary from 6%- 15% and are normally grate discharge types in most cases the densities of the slurry in the mill is over 65% and that goes for ball mills also. Off course you have a upper limit or the balls will "float" out. Higher densities allow better grind and increase residence time in the mill.
