The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills, because it controls the mills' throughput and performance. Efficient and effective discharge of pulp/slurry from the mill is the key objective of the pulp lifter design. The modelling showed high wear zones at the pulp lifter discharge outlet.

Optimizing your SAG mill operation - International Mining
The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.

Mill & Scrubber Linings - Multotec
Pulp Lifters. Manufactured from a fabricated steel base, which is then rubber lined, Multotec's pulp lifters ensure the correct volumetric flow. Rubber lined pulp lifters provide optimum discharge of pulp through the mill in order to minimise 'bottle-necks'. Rubber wear plates, bolted onto the high wear areas, achieve an improved life.

Liners for the Grinders | E & MJ
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.
