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 ...

The fragility of ore depends upon its strength. In a crushed product or mining product, the fragile ore degen-erate to a undesirable fine product during blasting, excavation, loading and transportation. Similarly in a crushing and comminution process by crusher, ball mill or rod mill, as the ore of high strength attains to a desired size, the fragile ore degenerates to superfine.
