SINGLE STAGE SAG/AG MILLING DESIGN ABSTRACT Single stage semiautogenous / autogenous (S/AG) milling has become a common design for a variety of ore types with the advantages of being comparatively low capital cost and flexible for future expansion. The single stage
It also led to the failure analyses, measurement and remedial design of many large ring motors in gearless mill drives (GMDs) including the catastrophic failure of the ABB motor at Colluasi. These projects also offered the opportunity to measure stresses in large SAG and ball mills including those at Colluasi and Telfer.
Having related SAG mill throughput to SAG mill power and the ball mill circuit P 80, the data was then reduced to a series of curves representing the relationship between the SAG mill specific power consumption (), which is the SAG mill power draw divided by throughput, and the ball mill P 80 for each UGM. Fig. 3 shows the six resulting ...
