Get DetailsMill type overview three types of mill design are common the overflow discharge mill is best suited for fine grinding to 75 106 microns the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns the centerperiphery discharge mill has feed reporting from both ends and the product discharges
Get DetailsDiverse 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
