  • Cement mill - Wikipedia, the free encyclopedia

    The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. Efficient closed-circuit systems, because of their tight particle size control, lead to cements with relatively narrow particle
