targets by lowering the throughput. Further, the SAG mill circuit was characterized by fluctuating feed size of between x. F, 80 =102 to 185 mm. A need for control of the feed size as well as blending ratios was recommended for an efficient operation in terms of throughput and final product size. This could be achieved through closer monitoring of

SAG mill ball charge determination and its influence on ...

In semi-autogenous grinding (SAG), the grinding mill inventory, (i.e. volume of total charge, volume of ball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest cost ($/t). A two-dimensional graphical method is presented for determining the actual ball charge within …

Major Mines & Projects | Waihi Operation

The SAG mill ball size is 125 mm and the mill will operate typically with a 10% ball load. The SAG mill draws between 2.1 and 2.5 MW of power. The SAG mill discharge is sized using a trommel attached to the SAG. The +12mm oversize material is conveyed to a 30 kW cone crusher and is recycled back to the SAG mill.

Ball Mill Efficiency Pdf - divinechannel.in

SAG Mill Ball Charge The SAG mill was simulated to require a 10-12 ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future.
