Mathematical model of ball wear in grinding mills I.

1986-3-1 · Finally, Bond [ 12, 13] suggests that the mechanism of ball wear is related to the grinding mechanism in each mill; when rolling and nipping predominates, wear depends on the ball surface, and if the size reduction occurs mainly by impact, wear rate depends on the ball mass.

Grinding Media Wear Rate Calculation in Ball Mill

2017-4-29 · In any mill, the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball

A discussion on the measurement of grinding media

2016-7-1 · Wear of grinding media One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement, as the wear of the grinding balls requires their substitution at intervals.

Effects of percent solids and mill loading on ball wear

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
