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 ...

And thus, the grindability of the iron ores was investigated. The results obtained are as follows: (1) The work indices of the iron ores are ranged from 6.22 to 17.40. The work indices of the Santa Barbara ore, the Santa Fe ore and the Chile ore are greater than 17 and these ores are remarkably hard.
