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.

Increasing the circulating load to 500 brings that value up to 2.6 times, for a further relative productivity increase of 30 2.62.0 1.30. By keep on increasing the circulating load, typically you reach a point where the mill is overfilled and milling efficiency decreases. thus, there is an optimum circulating load.
The circulating load increases with decreasing screen efficiency and as crusher product coarsens f or r decreases, which is related to the crusher set specifically the closed side setting, c.s.s.. For circuit a C also increases as the fresh feed coarsens n decreases, which is likely coming from another crusher. In this manner, the circulating load can be related to crusher settings.
