Oct 08, 2020 circulating load ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer. Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of separation curves, circulating load ratios, cyclone feed pressures, vortex and apex sizes etc Oct 09, 2015 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 of 100%, an additional stage of grinding and

Feb 21, 2015 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 usual definition of a circulating load is the (dry) mass flow returning to the mill from the classifier and is expressed as a percentage of the mass flow of new feed (Wills Min. Proc. Technology, 2016)

Get Price The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. Circulating load ratio is enormously important to grinding circuit efficiency. Diminishing returns dictate optimum economic operational values of approximately 350% to 400% for most primary ball milling circuits. 6 Slide 6 effective factors for circulating load
