2014-2-1  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.
