How a Grate Discharge Ball Mill Works

13/08/2015  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 rubber has allowed rubber manufacturers to ...

Grid Type Ball Mill VS Overflow Type Ball Mill, How to ...

The grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of the overflow type ball mill. The overflow ball mill discharges the ore by the gravity flow with the slow speed, so its production capacity is relatively weak, and because the material stays in the ball mill for a long time, it is easy to cause the over-grinding phenomenon ...

Converting a ball mill from overflow to grate discharge ...

23/06/2020  Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is ...

TECHNICAL NOTES 8 GRINDING R. P. King

K is a calibration constant that varies with the type of discharge. For overflow mills K = 7.98 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 ...
