Testwork: Bond rod mill work index - SAGMILLING.COM

The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus. The SAGMILLING.COM models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners". Most laboratories outside of Australia use the wave liner style of machine – these results can safely be used in the models. …

Bond Work Index - an overview | ScienceDirect Topics

The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger’s law. Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize) is given by
