In ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time for most companies the production mill already exists so we can ignore mill diameter and focus on the other variables
a total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to
Oct 19 2017 as practice shows the difference between the grinding balls average diameter in mill and loaded grinding balls diameter is 1015 mm in our example the grinding balls diameter needed to load into the mill must be equal to 4050 mm
Ball mill finish calculator the ball mill finish calculator can be used when an end mill with a full radius a ball mill is used on a contoured surface the tool radius on each side of the cut will leave stock referred to as a scallop the finish of the part will be determined by the height of the scallop amd the scallop will be determined by the stepover distance between cuts
