SAG mill ball charge determination and its influence on mill drive
Abstract: In semiautogenous 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 Mill Charge an overview ScienceDirect Topics,According to available literature, the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 80–85% of the critical speed.

SAG Mill Ball Sizing Grinding & Classification Circuits
With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to 2.5) for a coarse mill feed (say F80 > 110 mm). If the mill feed size is fine, say Optimum SAG Mill Discharge Density 911 Metallurgist,The optimum % solid depends on the material and rheology.If you want high throughput and a coarse product size you can run at <65% solids (assuming a hard rock feed with ore

SAG mill ball charge determination and its influence on mill
In semiautogenous 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 twodimensional graphical method is presented for determining the actual ball charge within PreProcessing to Increase the Capacity of SAG Mill Circuits,66· Reduction in the number of open pebble ports was even more detrimental to mill performance, as shown in the SAG12 test, compared to the SAG11 test. These two tests clearly show the influence of critical size accumulation in the SAG mill charge even with relatively high ball charge and mill speed.
