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.

The effect of ball milling on properties of the electrode can be gauged through rheological characteristics of the slurry.
