maximum feed size for ball mill

optimum choice of the make-up ball sizes for maximum

for the feed size of 90% passing 18.9 mm (fig. 6a), the maximum capacity was obtained with 100% of a make-up ball size of 50.8 mm. as the feed size is reduced to 13.4 mm, a 62:38 mix of 50.8 mm and 25.4 mm balls was found to be the optimum mix.cited by: 6

ball mill size

the feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. and the product of the large ag/sag grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a vertimill® or a stirred media detritor (smd).
