Grate Discharge Ball mills with low pulp levels benefit from the full impact of the grinding media acting on the ore particles, as it falls into the shallow pulp. With a deep pulp level the grinding media is cushioned in the pulp, thus losing its energy and reducing its grinding ability. Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power
Grate 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 15—25 % higher capacity per volume unit as compared with an Overflow Mill. The discharge trunnion can be furnished with trommel screen.

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 stone has allowed stone manufacturers to
The discharge opening is equipped with a discharge grate, and the ore pulp horizon of discharge opening is low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed. Under same circumstance, the processing capacity of energy-saving grate ball mill is bigger. Rolling bearings contribute enormous energy saving. Advantages. 1. The transmission machinery of

A crushing plant delivered ore to a wet grinding mill for further size reduction. The size of crushed ore (F 80) was. 4.0 mm and the S.G. 2.8 t/m 3. The work index of the ore was determined as 12.2 kWh/t. A wet ball mill 1 m × 1 m was chosen to grind the ore down to 200 μm. A 30% pulp was made and charged to the mill, which was then rotated
