2020-5-18Grate Discharge Ball Mill This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 1525 higher capacity per volume unit as compared with an Overflow Mill
With grate discharge mills – typically SAG, AG and ball mills – the conventional relining process at the discharge end usually involves removing the dischargers and grates, replacing with new lined versions and hammering in large, long bolts through the layers to secure the liner components.
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 ...
