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.

Ball mill introduction

Ball mill is a type of grinder used to grind materials into extremely fine powder mainly for use in mineral processing industry.The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overflow type due to different ways of discharging material. Ball mill rotate around a ...

TECHNICAL NOTES 8 GRINDING R. P. King

and for grate mills K = 9.10. This difference is ascribed to the presence of a pool of sl urry that is present on the bottom of overflow-discharge mills but not to the same extent in grate-discharge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not draw significant power.
