bond crushing law and and work index eduioncare.inWhat is bond's law of crushing Answers.com. Where Kb is a constant that depends on the type of machine and on the material being crushed. To use this equation, a work index Wi isA meaningful expression between bond work index The relationships obtained between the indices were in surprisingly good agreement, with high correlations (0.99 and 0.97). The Bond work index and the grindability index can therefore be estimated from the friability value, which can be determined more rapidly than from the Bond test.
