definition of circulating load in mills

Ball Mill Circulating Load

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

Circulating Load Calculation Formula

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 ...

(PDF) Effect of circulating load and classification ...

The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962).
