A discussion on the measurement of grinding media wear

01/07/2016· The grinding media may be the ore itself (autogenous grinding), bars, balls, or cylpebs, or even the ore itself together with a small amount of balls (semi-autogenous grinding). A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi-autogenous grinding, and therefore nearly 90% of mining operations are users of balls
