All Mill Discharge Grate Vs Overflow

Jun 23 2020 the slurry pool in the bottom of an overflow mill as it rotates creates a cushion onto which the balls fall which reduces the energy of impact of the balls this reduced impact energy results in a reduced rate of breakage across all size fractions inside an overflow mill compared with a grate discharge mill
