The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution.

Grate ball mill is mainly composed of barrel part, feeding part, discharging part, bearing, transmission system and lubrication system. After the grate type ball mill starts, the material is fed into the barrel through the feed end, and the barrel then rotates around the horizontal axis according to a certain speed.

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.

If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.

"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 design and production of finer product. In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge end. Hence there is a
