is ball mill a closed system. Closedcircuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine 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.
