LOCKED CHARGE STARTS AND YOUR GRINDING MILL Jeff

SAG and ball mills with grate discharge are not prone to locked charge events because of the high amount of rocks and balls compared to fine ore. The pulp dischargers of a SAG mill continually pump the finer material out of the mill, lowering the total amount of residual fine ore and thus improving the situation in respect to locked charge starts.

Grate Discharge Advantage & BenefitsGrinding

In simple words, grate discharge mills give higher tonnage, but produce coarser grinding, that may cause problem in your Flotation recovery, Grate discharge will also reduce your EGL. The best option would be to place a retainer ring at discharge end to hold more charge & that will give you more throughputs without compromising grind size.

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.
