How a Grate Discharge Ball Mill Works

2015-8-13  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.

Overflow Versus Grate Discharge Ball Mills: An

2021-7-14  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

Slurry flow in mills: grate-pulp lifter discharge systems

Pulp lifters, also known, as pan lifters are an integral part of the majority of autogenous (AG), semi-autogenous (SAG) and grate discharge ball mills. The performance of the pulp lifters in conjunction with grate design determines the ultimate flow capacity of these mills. Although the function of the pulp lifters is simply to transport the slurry

Analysis of specific discharge rate functions in

2015-4-1  According to Leung’s definition, the discharge rate is considered to be the product of two mechanisms, transport and classification by the grate. if there is not any particle classification at the mill discharge, particles behave like water and the discharge function is invariant with particle size as stated by Morrell and Man (1997).

The effect of grate design on the behaviour of grate

Abstract 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

Converting a ball mill from overflow to grate

2020-6-23  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.
