List Factors Affecting Grinding Ball / Media Wear Rate
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 charge volume. The wear rate exponent for SAG milling was experimentally determined to be n = 2.8.
