The cement mill

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding…

Gypsum Addition - an overview | ScienceDirect Topics

For this reason closed circuit mills have been developed in which the finer material is removed by a separator while the coarser grains are returned to the mill for another circuit. This can produce a cement with the same surface area as the open circuit mill but without the very fine material and without the coarser material.

Cement mill - Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
