  • A discussion on the measurement of grinding media

    2016-7-1 · 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 as grinding Fineness of Grind and the Consumption and Wear Rates ,Rate of Grinding media (glmin) (t/h) 425 >211 > 150 > 106 >75 >53 > 45 <45 mean size production of Consumption Wear rate 300 pm zi” (mm) -75~l.trn material Pm Ctm Pm Pm Pm Pm (kg/h) (kg/t) (g
