SAG Mill Pulp Dischargers

Modern Semi-Autogenous (SAG) Grinding Mills can be up to 12 metres in diameter (absorbing up to 20 MW of power) and need to discharge over 2500 tonnes per hour of solids via pulp lifters. Pulp lifters take the form of a radial array of "box-section" channels mounted inside the discharge end wall of the mill.

An efficient pulp lifter for ag/sag mills

The geometry of conventional pulp lifters is such that the slurry, once passed through the grate into pulp lifter will always be in contact with the grate until it is completely discharged, which makes the 'flow-back' process inevitable (Latchireddi, 2002).Though the impact of flow-back may be of lower magnitude in open circuit grinding, it can make a …

A New Design of Pulp Lifter for Grate Discharge Mills

Extensive test work carried out on slurry removal mechanism in grate discharge mills (ag/sag) has shown that the conventional pulp lifters (radial and curved) have inherent drawbacks.

The optimal performance of AG/SAG mills is the key to successful plant operation. All AG/SAG mills using radial or curved pulp lifters suffer from inherent …

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 ...

SAG Mill Liner Design

To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered. Each of these topics has had a considerable amount …

SAG mill pulp-lifter design, discharge and backflow

Mining Engineering, 2006, Vol. 58, No. 9, pp. 57-57Royston, D. ABSTRACT: Conventional straight-radial semiautogenous grinding (SAG) mill pulp lifters suffer from incomplete discharge of the rock portion of the charge. The resulting backflow of undischarged rock limits pulp lifter performance and is the major source of wear in pulp lifters.
