Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. for the initial chargin of a mill, coghill and devaney () defined the ball size as a function of the top size of the feed, i.e., d †“v = 0.40 k ˆšf db = ball size (cm) f = feed size.One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. a f80 = 6 mm would need a ball size of 75 mm. an empirical model from emerging trends in mineral processing , , is.
The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. materials are put in cylinder through the feed opening and then thoroughly grinded. the falling course of iron balls and ores can produce huge falling impact and autogenous grinding.it is a high technological enterprise that integrated research.Understanding ball mill sizing industrial engineering . micromorphological changes and mechanism associated with wet ball milling of pinus radiata substrate and consequences for saccharification at low enzyme loading. bioresource technology 214 a comparison of the bond method for sizing wet tumbling ball mills with a size. chat.
