We can calculate the steelchargevolume of a ball or rodmilland express it as the % of the volume within the liners that is filled with grinding media. While themillis stopped, thechargevolume can be gotten by measuring the diameter inside the liners and the distance from the top of thechargeto the top of themill. The % loading or change volume can then be read off the graph below or

Sep 01, 2013· It was found that theoptimumcomposition depends on various factors, including the feedsize, the productsize, themilldiameter and the breakage parameters. In all cases, binary mixtures of two ballsizes(50.8 mm and 25.4 mm) performed better than a mixture of the three ballsizes

A 13′ x 6′ SAG Mill has a reasonable range of: 20 to 30 TPH for gold ore SAG & Ball Mill duty; 25 to 40 t/h for copper porphyry SAG & Ball Mill duty; In Single Stage SAG duty, the approximate capacity reduces to only 8 to 13 TPH for gold ore duty

SGI products are designed for compatibility to blendsizesand grades to create anoptimalballchargeof controlled ballsizedistribution. Even wear technology is another aspect of SGI products that ensures superior performance. The even wear allows for the new life potential of media rejected from portedSAG…

Critical speed is defined as the point at which the centrifugal force applied to the grindingmill chargeis equal to the force of gravity. At critical speed, the grindingmill chargeclings to themillinner surface and does not tumble. Most ball mills operate at approximately 75% critical speed, as this is determined to be theoptimumspeed
