The SAG mill was originally equipped with radial pulp lifters. The mill runs at fixed speed of 10.9 revmin, 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
Curved Pulp lifters assist the movement of the charge to the centre by initiating motion of the charge earlier than is the case with straight lifters. This moves the charge towards the centre of the mill where, relative to straight pulp lifters, it can be subject to earlier and stronger application of the inward motion gravity forces.

Extensive test work carried out on slurry removal mechanism in grate discharge mills agsag has shown that the conventional pulp lifters radial and curved have inherent drawbacks.
Jul 01, 2003 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 .
A pulp lifter and a pulp lifter assembly are described for a rotary grinding mill. The pulp lifter has a leading edge and a trailing edge with respect to rotation of the mill, and includes a first wall bounding an interior space and a second wall dividing the interior space into first and second regions. The first wall includes a leading edge wall formed with at least one inlet opening ...

The results obtained indicate that the optimum number of lifters for pilot-scale SAG mills is between 16 and 32 lifters with medium thickness. ... extend the life of the outer pulp lifter and ...
The backflow of non-discharged rocks can limit the pulp-lifting performance and add to wear at the base of the pulp lifters. Adequate front-to-back depth in pulp lifters is necessary to ensure good pulp-lifting performance, with some SAG-mill operators having adopted curved pulp lifters, especially of the hockey stick shape.
