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

Ball Mill Wear Test911 Metallurgist
· When a lump of ore is crushed by the impact between two balls in a ball mill it is considered high-stress three-body abrasive wear. The abrasive wear of balls that results from the milling of ore is the major wear loss in most minerals processing plants. During the wet milling of ores abrasive wear

List Factors Affecting Grinding Ball / Media Wear Rate
· The wear rate exponent n is essentially equal to 2 for conventional ball milling. When n = 2 the production wear rate is directly proportional to the wear speed as determined by MBWT according to the equation WR = R(WS) (CW)/(DR) (TpH) In addition to wear speed ball size and recharge practice charge volume and feed rate are significant factors affecting the actual production wear rate. Wear speeds are largely independent of ball size and ball

Grinding Media Wear Rate Calculation in Ball Mill
· 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. This is seen to be Kick s law.
