STARTLING EFFECT OF BALL SCATS REMOVAL ON SAG MILL …

the ball scats from a single-stage SAG mill. These scats are non-spherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates had increased dramatically at the coarser end of the size distribution. This work highlights the importance of ...

Optimizing your SAG mill operation - International Mining

Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400-500%. The geometry of radial and curved pulp lifters is such that the slurry, once passed through the grate into the pulp lifter, will always be in contact with the grate until it is completely discharged, which makes the ‘flow ...
