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..keeping those ball mills turning – let's roll,from a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill. and obviously, the ball mill bearings are massive in size – which is why they get a lot of attention and are expensive to manufacture,” explains cbc australia engineering manager anthony o’keefe. “the pinion bearings are much smaller, but they are heavier duty. their performance is vital to the whole ball mill.how to find a ball mill circulating load 」,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..locked charge starts and your grinding mill jeff belke,the mill. maintain an adequate ball charge - too low a ball charge is one of the leading causes of locked charge starts, especially in ball mills. power draw should be maintained over 75% of mill rated power. a locked charge mitigating start procedure must be utilized if the mill is shut down for 15 minutes or longer. the timers should be
