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
7/09/2011· 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%.
18/11/2014· Slide 2 Content Introduction Circulating load calculate Most factories the purpose of control Effective factors for circulating load Test design Conclusion References 3. 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.

Definition of circulating load. i. In mineral processing, use of a closed circuit to check mineral issuing from a specific treatment and to return to the head of the treatment those particles that do not satisfy the maintained conditions for release to the next stage of treatment. Ref: Pryor, 3 ii. In ore dressing, oversize material returned to a ball mill for further grinding. Ref: Newton, 1
A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in
In order to maintain the same flow gradient, the load inside the mill increases and the mill draws more power. In turn, this leads to a higher rock to ball ratio, resulting in insufficient grinding energy and a further increase in load inside the mill. Pebbles flow-back
Likewise, if the circulating load is low and the product too fine, even with a high ball charge or mill speed, the circuit selection may be incorrect. If a recycle crusher was not included it should be trialled.
