sag mill pulp lifters. Performance characterisation of AGSAG mill pulp 812014 The pulp lifter is anponent of autogenous AG and semi autogenous SAG grinding mills as it controls the throughput, performance and e
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.
This is particularly noticeable when agsag mills are run in closed circuit with classifiers such as fine screenscyclones. 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.
Jun 01, 2006 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 noticeable impact when the mills are ...
