Grinding Mill Ball Charge

NIOSHTIC-2 Publications Search

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 cataracting-centrifuging masses, resulting
