# ball size effect on grinding mill

### The effect of ball size on the energy efficiency of hybrid high

It is well known that ball mill efficiency is affected by the size of the grinding media and that there is an optimum ball size that is strongly related to particle size. Bond 5 developed an empirical relationship based on maximum breakage rate in which the ideal ball size is proportional to the square root of the product size.
