A grate assembly at the discharge en d of the mill permits retention of a higher ball charge (up to 50%) than is possible in an overflow mill which has a practical limit of around 40%. Behind the grates is a lifting compartment which picks up the ground material as it passes through the grates and transports it out of the 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.
