2013-12-1  In this figure, the positive influence of the smaller ball size on the milling efficiency is drawn by an arbitrary negative slope with ball size rather than the dependency of d −3, because the dependency of d −3 is valid only in a stationary state of ball packing while the actual ball milling is a dynamic event taking place under the presence of the powder slurry existing between the balls. Actually the

2009-6-1  Ball mill performance is greatly affected by ball size. There are many factors affecting the choice of suitable ball size, such as feed size distribution, feed hardness, mill diameter, specific gravity of ball, etc. Bond has suggested a formula to determine the maximum ball size including most of these variables . Although it has been widely used, Bond’s method could not be used to correlate breakage rate with ball size

2018-6-1  The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate.
