Current Experience With Curved Pulp Lifters

Curved pulp lifters can provide improved discharge performance from SAG mills, especially for the coarser fraction of rocks in the discharge. They also can provide improved wear life of the pulp lifter, especially the base of the pulp lifter and diversion cone, over comparable straight radial pulp lifters. Current experience with curved pulp lifters and associated grates is covered including design issues and discharge performance for both the slurry and rock components of the discharge.
