High recirculating loads in Ball Mill Circuits
Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =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.
