Solid particles and coarse pebbles also flow-back through the grates along with the slurry. While flow-back of slurry leads to pool formation, flow-back of pebbles increases the quantity of critical size material in the mill. The amount of pebbles passing through the grate increases with the angle of the grate.

The installation of theOpen Ended Discharge Grinding Mill - Metso Outotec,The OED Mill delivers the highest possible discharge capacity by eliminating the need for pulp lifters; instead, material is discharged directly through the grates, solving the throughput bottleneck problem often associated with comminution circuit design. The pursuit of high-efficiency pulp discharge systems by mill and liner suppliers is a testament to the potential

The mill runs at fixed speed of 10.9 rev/min, which is approximately 80 per cent of critical speed (per cent CS). Due to the high speed of the mill the original radial design pulp lifters presented a high volume of recirculating load inside the chamber and consequently heavy wear on the outer circle (bottom pan).
