How a Grate Discharge Ball Mill Works

Ball Mill Discharge

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 gratescreens are veins like a pump impeller. As the mill turnsrotates the slurry is pumped out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to
