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. (2). So the production of cement clinker is ...
