### Small-Scale Tests to Characterise Ore Grindibility

The crusher work index (cWI) or impact work index is calculated as follows: Where J is the energy at which the specimen broke, mm is the thickness of the rock specimen, and S.G. is the specific gravity of the ore. The J/mm are transformed in kWh/t as follows: The test is generally performed on 20 rocks, which is relatively small, resulting

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...
