Effects of percent solids and mill loading on ball wear in

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp

Diverse ball milling conditions were employed by changing ball size, media charge, mill speed and slurry hold-up 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
