An increase of over 10% in mill throughput was achieved by removing the ball ss from a singlestage SAG mill. These ss are nonspherical ball fragments resulting from uneven wear of balls with included porosity. 30t of ss were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates had increased dramatically .

Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (, a ball nose mill) or directly from the cutter's shape (, a form tool such as a hobbing cutter). Go to Article.
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. FullerTraylor SAG/AG Mills range in size from through in diameter with powers as high as 28,000 kW.
