Crusher were compared with those of the Bond crushing energies (estimated from the Bond crushability index) of the rocks. Also, the effect of the Bond crushability index on the estimated crushing energy of the rocks was studied. Materials and methods In this work, nine different rock specimens were obtained from some mines in Iran.May 29, 2019 The Bond work index (BWI), expressed in kilowatt hours by ton, characterizes the potential for a material to be reduced from a theoretically infinite size to a powder with 80 particle size less than 100 μm. The BWI value is 13 kWh t and 14 kWh t for dolostone and limestone, respectively (Lowrison 1974).
