Unless the ore slurry is viscous, aim for a milling density in the vicinity of 42% solids v/v (not w/w). Adding balls = more mill power and a finer grind generally (in a ball mill anyway). In an open circuit SAG mill, more balls can actually destroy the intermediate pebbles that do the low energy abrasion grinding, producing a coarser grind.
