Modelling the performance of grates and pulp lifters in ...

Autogenous (AG) and Semi-autogenous (SAG) mills have been used since the early part of the Id^ century. One of the important components of these mills is the discharge assembly which comprises a grate and, in the majority of mills, an array of pulp (pan) lifters. However, despite the importance of grates and pulp lifters the literature contains very little information on their …

A laboratory study of the performance characteristics of ...

A single pulp lifter segment representing 1/1@ of the cross-sectional area of the mill was attached to one of the panels in the grate. Its discharge was collected independently through a separate launder. By multiplying this flowrate by 16 the equivalant flow for a full pulp lifter assembly was calculated.
