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
· The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.

· Ball mills are also classified by the nature of the discharge. They may be simple trunnion overflow mills, operated in open or closed circuit, or grate discharge (lowlevel discharge) mills. The latter type is fitted with discharge grates between the cylindrical mill body and the discharge trunnion.
Dry Ball Mill Discharge Grate. Grinding in Ball Mills: Modeling and Process Control. or double helical scoop feeder. Several types of ball mills are distinguished depending on the discharge system and these types are commonly known as overflow discharge mill, diaphragm or grate discharge mill and centreperiphery discharge mill, see .
The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of .
· Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling are charged with a small amount of steel balls to assist in the size reduction. These are known as semiautogenous grinding (SAG) mills. In the mining industry all of these types of mills .
