bond work index grinding equipment sizing It is a standard measure that brings all size reduction circuits onto a common basis for comparison. It starts with Bond's Work Index equation: W is the work (energy) input per ton. F80 is the 80% passing size of the circuit feed, and P80 is the 80% passing size of the circuit product, in microns.

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 ...

BOND WORK INDEX. The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond's Work Index equation is: W=WI* (10/√P80 -10/√F80) where. W= the energy input (Work input) per ton, …
