Closed Circuit mill along with latest high efficiency separators ensures proper particle size distribution of cement. The mill ventilation air carries a small portion of the fine material, which is dedusted in Bag filter. This is critical from the perspective of protecting the environment.

Closed-circuit systems[edit] 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.

Closed circuit ball mills are existing with all types of separators grit, mechanical and high efficiency in cement industries. Presently high efficiency separators are common to achieve maximum energy optimization. Brief description of separators is presented at the end. Primary Ball mill controls are:
