Overflow VS Grate Discharge Ball or Mill - Why Retrofit

Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills are used when the grinding energy shall be concentrated to the coarse particles without production of slimes.

of overflow-discharge mills but not to the same extent in grate-discharge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not draw significant power. Austin recommends K = 10.6 for overflow semi-autogenous mills. A value of K = 9.32 makes Austin’s formula agree with Morrell’s data
