Diverse ball milling conditions were employed by changing ball size media charge mill speed and slurry holdup in order to study the effect of polymeric dispersant aids on the grinding of dense slurries in the absence of a dispersant as the pulp thickens there occurs an increasingly disproportionate split of the grinding charge between cascading and cataractingcentrifuging masses resulting
