The charge motion and breakage of particles inside the mill depends on the shell lifters design, while the discharge of ground particles is controlled by the grate and pulp lifters. The limitations imposed by poor grate and pulp lifter design become increasingly apparent with increasing size of ag/sag mills and their operation in closed circuit.

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.

The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills as it controls the throughput, performance and efficiency of mills. The slurry transport from the AG/SAG mill through grate holes into the discharge trunnion is the main function of the pulp lifter.

Pulp lifter design can be a significant consideration for SAG mills, particularly for large mill. All mill sizes increases, the required volumetric capacity of the pulp lifters grows proportionally to mill volume. Semi-autogenous grinding mill liner also called SAG mill liner, Autogenous grinding mill liner also called AG mill liner.

issues that is detrimental to mill throughput. Furthermore, pulp lifters are inherently prone to carry over flow and flow back. Then there is the issue of radial pulp lifter versus curved pulp lifters; which one is suited for a particular SAG mill operation? Finally, the quantity of flow through grates into the pulp lifter is still lacking.

Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).

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.

A pulp lifter is used in grate discharge mills to pump the ground ore from the mill. An inefficient pulp lifter can cause a slurry pool to build up in the mill, resulting in partial dissipation of charge (balls and rock) kinetic energy into the fluid, reducing the energy available for breakage.
