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 ...

[PDF] A quick method for Bond work index approximate

2016-11-1  The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is subjected to errors.

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.
