The Bond rod mill work index is used to calculate the power requirement at intermediate size, i.e. from 12.5mm to about 1mm. The test has been mainly used for the design of rod mills or primary ball mills, but it can also be used along with the other Bond tests (BWI and cWI) for SAG mill design using semi-empirical relationship [6].
