THE INFLUENCE OF SHELL GRATE AND PULP LIFTERS ON SAG MILL

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.
