Closed-circuit Clinker Grinding Mill. Manufacture of cement requires the use of mills that operate with large power consumption. In addition, their capacity and operation must be optimized in order to obtain an efficient performance.

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.
