Thus, the test work index value multiplied by the product of the correction factors will provide an estimate of the true (plant) work index value. (3.42) W i = W i TEST × F 1 × F 2 × ⋯ × F 7 × F 8. Factors for condition not applicable should be taken as 1. The Bond work index value changes with the sieve size chosen during a particular test.

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 ...
