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.

Cascading Mill: A Phenomenological Design For Improved

Jan 01, 1998 The net powerrecorded for the cascading mill and the ball mill were 147 and 165 watts respectively. After each experiment, sieving was done and each sieve fraction was carefully weighed. Other experimental data pertaining to the experiments is given in Table 1. To assess the potential of the cascading mill, a comparison of grinding data was made.
