    Feb 21, 2015 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 ...

    Feb 01, 2014 Mill grinding flux is related to “New feed” and “Return flux”. However, adjusting the circulating load will cause a series of chain reactions, for instance, reducing the circulating load will cause CKP mill vibration and add the output material flux of cement clinker, as shown in the Eq. . So the production of cement clinker is adjusted to achieve the best crushing rate of cement clinker.
