Dec 01, 2006 For grate discharge ball mills the absolute slurry level should be flush with the surface of the charge, as a check on the discharge capacity of the mill. If the slurry level is well below the charge level, as in Fig. 1b, then the hold-up of the mill must be increased, usually by decreasing grate open area. A high slurry level is not to be ...
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

Jun 23, 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 ...
