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. Discharge Grates

Converting a ball mill from overflow to grate discharge

Jun 23, 2020· Converting a mill from an overflow to a grate discharge arrangement leads to an increased power draw. This happens because the installation of the grate discharge arrangement enables the mill to run with a lower level of slurry due to it being no longer necessary for the slurry to build up inside the mill until it overflows from the mill discharge.

Horizontal Grinding Mill Overflow Type, Grate-discharge

The grate-discharge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh.

Overflow Versus Grate Discharge Ball Mills: An

In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge end. Hence there is a possibility for much quicker transport of material through the mill, which is being accomplished in overflow mills by higher circulating load.

WO1998001226A1 Twin chamber pulp lifters for grate

A pulp lifter for a grate discharge mill used primarily in mining operations. The lifter comprises a plurality of chambers which radiate outwards. Each chamber comprises a transitional compartment (2) having apertures (19) into which the slurry enters and a collection compartment (21) to which the slurry passes. When the pulp lifter rotates, the slurry cannot flow back but must pass to the

The effect of grate design on the behaviour of grate

Sep 01, 1986· A model for the effect of flowrate and viscosity of slurry on the hold-up of slurry in a grate-discharge grinding mill has been developed. Given detailed specifications of the grate design (such as the area in the grate within which the holes are situated, the number of holes per m 2 and the hole size) and the flowrate and viscosity of the slurry flowing through the mill, the model provides
