• Bond Work Index

    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 .

    Luckie [1]) Bond work index may be useful for mill design, but not for optimization of operating ball mills. The main limitations of Bond´s equation are associated to the fact that it does not allow decoupling the contributions of the mechanical environment, the mill transport and size classifiion. As such, the empirical equation for specific energy calculation implicitly assumes that the ...
