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.
