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
