• ## Calculate and Select Ball Mill Ball Size for Optimum Grinding

· Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^05 where D m = the diameter of the singlesized balls in mmd = the diameter of the largest chunks of ore in the mill feed in mm dk = the P90 or fineness of the finished product in microns (um)with this the finished product isvolume charging formula in ball mill Jan , rod mills are very similar to ball mills, except they use long rods for grinding media the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball millTo prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about mm in and produce avolume charging formula in ball millVolume loading formula in ball mill mill load or charge volume is the cumulative sum of the grinding media, information show that 40 load by volume of ball mills result in get price energy calculation model of ball kinematics based on of ball mill and ball motion under the influence of coal load are analyzed carefullyVolume Loading Formula In Ball Mill Ball Mill News
