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.

But closed circuit system is adverse to open circuit system. The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber. Then the grinding efficiency and capacity is improved. In general, the capacity can be improved by 10%-20% compared with cement mill when these specifications ...
