Jul 20, 2017 Crushing the coarse circulating load, which can be a critical size, as described by Pickands Mather and Newmont Mining, can also be tested in the pilot plant. In conjunction with pilot plant testing, there should be either pilot plant facilities or at least bench scale facilities to test the suitability of the product for the next processing step.

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.
