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 8hour shift allowing to calculate corresponding to circulating load
Why do ball mills have such high circulating loadsthe 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 circuita recent grinding bulletin addresses this question f
