Hence, the cement grains show a lower resistance to comminution. These provides benefits to grinding efficiency by. Reduction in agglomeration and coating of the mill internals. Improved dispersion of feed to the separator - Increased separator efficiency and lower by-pass. Reduction in the mill filling level.Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns. The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges.
