2015-6-16 The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings ( jaw crushers and gyratory crushers) or closed-side settings (cone crushers)

The Bond Work Index is calculated using the formula: 𝑖=1,1 44,5 𝑃𝑐 0,23𝐺,82(10 √𝑃80 −10 √𝐹80) (1) where W i – Bond work index (kWh/t) P c – test sieve mesh size (µm) G – weight of the test sieve fresh undersize per mill revolution (g/rev) F 80 – sieve mesh size passing 80% of the feed before grinding(µm) P 80

MoreThe Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger’s law. Accordingly, the energy consumed in reducing the particle size from x F to

MoreThe 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 ...
