Also with low ball charge slurry pool will reduce grinding efficiency Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy I think at …
Modern mills operate with load cells and mill optimizer s which synchronize the mill weight power draw ore feed and weight with density control Where optimizers are not used the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids
Dry batch milling tests were performed in a laboratory scale ball mill measuring 30 2 by 28 2 cm The mill specifications are given in Table 1 A constant ball load of 20 was maintained in all the tests with a ratio of 0 5 for binary and 0 33 for trinary ball mix
In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimum ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize just in case Well this safety factor can cost you much in recovery and or mill liner wear and
