A discussion on the measurement of grinding media wear
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 (semiautogenous grinding) A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semiautogenous grinding, and therefore
THE EFFECT OF BALL MILL OPERATING PARAMETERS ON
