Control Of Corrosive Wear In Grinding Balls During Wet
jan 01, 1991 during wet grinding of hematite ore in a synthetic mill water containing 2.0 gL and 0.5 Cl the amount of ball wear in a min run was 0.78 mgm. ball wear can be reduced by the use of inhibitor ranging from to for single As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. the risk of underloading or overloading the mill is an additional factor. direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, isthe 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- material reached maximum at 70% solids, whereas the ball wear decreased as pulp
