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.
Ball mills are usually either of the grate ( diaphragm) or overflow type. Ball Mill Components Ball mills consist of the following components: Inlet crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge reduced feed exits the mill through the discharge. Ball Mill Components
