SAG Mill Comminution (SMC) Test The SMC Test is conducted on a single size range which is typically -31.5 mm +26.5 mm, hence the sample requirements are less than drop weight test. The test generates the Drop Weight Index (DWI) which is expressed in KWh m 3 , which strongly correlates to values generated from a Drop Weight Test.
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.

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.
