    The Bondrod mill workindex is not as common as the Bondball mill workindex, 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.
