The Bond work index is not solely a material constant but is influenced by thegrindingconditions. For example, the finer the grind size desired, the higher is thekWh/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 undersizeperrevolution, G, and ...

    The calculated liner and ball wear is expressed in kilogramsperkilowatt-hour (kg/kWh), and when multiplied by the specific power (kWh/t), the wear rates are given in kilogramsper tonof feed. The wear in dry ball mills is approximately one-tenth of that in wet ball mills because of the inhibition of corrosion.

    Secondarygrindingefficiency (as measured bykWh per tonfiner than 75 microns or Work Index), was improved substantially by reducing the pebble size to 20/28mm. The process as a whole was optimised when crushed rock coarser than 4 mm was recycled to primary mill, as the small pebbles were most efficient with “sand”.
