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.

2013-3-13 Mill Load Control strategy uses the traditional signals such as mill sound and recirculating bucket elevator power as well as the mill power to determine the mill load level. This load level is defined as the total of the grinding charge and material in the mill. The control strategy attempts to keep this load level as constant as possible. This load level is compared against the set point derived from the mill

Use of Locked-Cycle Protocol to Assess Cement
Laboratory grinding mills operated for a given time interval do not consider the effect of circulating load (CL), thus generating excessively wide cement particle size distribution (PSD) curves that are not representative of what is normally obtained from real-scale mills. The main objective of this paper is to develop a locked-cycle protocol that takes CL into account and mimics the clinker
