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 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 ...

7-9-2011· Re: VRM and ball mill circulating load. Mainly in USA , the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.

lation of the circulating load was achieved. At each iteration, the circulating load CL is calculated using the following equation: CL=∑ n i=1 (p. i.f. i ) (2) Where fi is the flow (voul metric or mass) which feeds the i-th unit, an operational unit that contributes directly to the circulating load …

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
