## 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.

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

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

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).
