Overflow VS Grate Discharge Ball or Mill Why Retrofit

The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.

How a Grate Discharge Ball Mill Works

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to
