→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

Rock specimens break since tensile cracks develop parallel to the loading direction. In general, it has been found that the value of the load P at failure depends largely on the core diameter. Hence, the results of point
