Mill liners image 13574 When the rock load is low excessive balltoball contact retards the rate of breakage Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter Other factors include

Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones

The Bond Abrasion Test determines the Abrasion Index which is used to determine steel media and liner wear in crushers rod mills and ball mills Bond developed the following correlations based on the wear rate in pounds of metal wearkWh of energy used in the comminution process Wet rod mill Rods lbkWh 035Ai – 0020 02 Liners

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
