Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load

Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent grinding bulletin addresses this question f

Ball Mill Recirculating Load The ball mill’s recirculating load was expected to be 250%. This corresponds to a volumetric flow of 2700m3/hr. However as with a large number of base metal milling circuits the Santa Rita milling circuit operates at a maximum recirculating load of 150%. The result of the lower recirculating load is that
