    Circulating Load Calculation Formula

    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.

    Effect of circulating load and classification efficiency

    Ball mill capacity tends to increase with larger circulating loads, but this increase is restricted due to limitations in classification efficiency. Classification efficiency is defined as the percent of final product size material recovered to the classifier fine stream.
