The results obtained show that weight retained varies from g to g for granite while that of ironore vary from g to g. In addition, it was observed that granite and ironore have grindability values of g/rev and g/rev respectively. This confirmed that granite requires more energy to be grinded.
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, .
