The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962).
Get PriceHere 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 ...

Get PriceThe circulating load can be defined as a process flow (mass or volumetric) of a given material that returns to a unit operation after failing in some selection criteria. This disapproval may be due to an imperfection in the selection equipment or due the material being out of the specification accepted by any subsequent step in the process.
