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 …
