2015-6-16 Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work

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

In the 50s Bond came up with an empirical relation covering the range between Rit- tinger and Kick's law, correlating the mass specific comminution work WM,K. Work Index Metcom Expertise. 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: w1. W is the
