  • Ball Mill Circulating Load Mineral Processing &

    · The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding That is, for every incremental increase in circulating load· In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be made clear by Fig 71 The trend to the use of higherCirculating Load Calculation Formula· Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit Circulating load circulating load ratio New feed circulating load ratio [8] 4Circulating load SlideShare
