Circulating Load Calculation Formula - 911 MetallurgistSep 10, 2017 . 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.ball mill cyclone,Cyclone Monitoring System Improves - CiDRAKennecott Utah Copper's (KUC) Cop- perton Concentrator has four grinding lines each consisting of one semi-auto- genous SAG mill feeding two ball mills in a closed circuit with a hydrocyclone battery (See Figure 1). The aim of the ball mill/cyclone circuit is to produce the optimum flotation feed particle size.

### Why Do We Need Such A High Recirculating Load On Our Ball Mill

WHY DO WE NEED SUCH A HIGH RECIRCULATING LOAD ON OUR BALL MILL? The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what purpose is served by having such a big pump, which is expensive to operate and maintain in our grinding circuit? There is a two step answer to.
