More3 at circulating load of 2.52, which indicates the availability of more classifying air in the system. − Due to high separation air, to production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum. The maximum power point is dependent upon the feed material characteristics, mill liner conditions, grinding

MoreHere 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
