Bond Work Index an overview ScienceDirect Topics

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

their diameter (Figure 2a). The point load index, Id, is equal to where P is the load at rupture and D is the core diameter. 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
