Eliminate SAG flow-back and carryover of slurry
We developed lifter, grate, pulp lifter and flow cavity through exit trommel model for the 40 ft Cadia mill in Australia. The study identified all wear zones, granular flow back into the mill and re-circulating flow inside the pan cavity for straight and curved lifters. At the time, we also modelled the water flow regime through the grate.

Slurry flow in mills: grate-pulp lifter discharge systems
Since the slurry in pulp lifters is always in contact with the grate, flow-back is unavoidable in both radial and curved pulp lifters leading often to higher hold-up values inside the mill. This may cause a slurry pool, which has adverse effects on the grinding performance ( Morrell and Kojovic, 1996 ).

Curved Pulp Lifters – Can They Save Energy?
The SAG mill was originally equipped with radial pulp lifters. 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

In the case of the curved pulp lifter flow-back III-243 is also reduced but in this case it is the result of its design causing slurry to flow down the pulp lifters to the mill exit earlier than in the case of the radial design. As a result, when the pulp lifter reaches the flow-back SAG mill and pooling and slurry transport was identified
