    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. Amstar SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28 000 kW. The most important benefits of Outokumpu s shell supported mills are clearly shown in this diagram. A 10 MW shell supported mill consumes the same foundation space as a 5 MW mill supported on traditional trunnion bearings. This feature provides significant savings in the cost of civil works associated with the mill installation as well as time

    The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.

    The results in SAG-Mill line 2 are even more dramatic. Because of segregation on the coarse feed stockpile SAG-mill 2 receives a higher percentage of coarse material. The KnowledgeScape strategy s ability to maintain smooth and stable operation of the mill was more apparent when contrasted to the DCS control on the "difficult" line. In these mills total charge volume occupies approximately 35 of the mill interior and the charge is lifted by lifter bars along the interior of the mill shell as the mill rotates.
