2014-3-6  The Bond’s work index of the above rock samples calculated from the Hardgrove index value has shown a variation from 7.7 to 10.3 kWh/sh.t. A correlation is found between the friability value and work index. The correlation coefficient of 0.93 between the friability value (S 1 ) and Bond’s work index, Wi = -18.193 Ln (S 1 ) + 66.747 has been ...

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 ...

Grindability characteristics of lateritic and karst ...

Research highlights Grindability characteristic of five different kinds of bauxite was investigated. Temperature and alkaline media have significant effect on the grindability. Possible reasons of the Bond work index decrease were revealed. The grinding work of bauxite should be divided by an empirical adjustment factor. The factor strongly depends on texture and type of bauxite being tested.
