Abstract
Wear processes in ball and rod mills have recently received increased attention in order to increase efficiency and conserve grinding media. Direct removal of metal from the grinding media surface by abrasive wear occurs in both dry and wet grinding. Additional corrosive wear is apparent during wet grinding, in which less resistant corrosion product films are abraded away. Inhibitors and higher pH solutions, in which corrosion product films are more tenacious, improve wear resistance during wet grinding. Softer surfaces are less resistant to corrosive wear, suggesting that film formation and subsequent film abrasion on newly furrowed surfaces must be a factor.
