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 represented by the product – the feed.

The 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 x p (both measured as 80% undersize) is given by.

The models for determining the power required for operating jaw crushers have mostly been derived using Bond’s work index. While these gave satisfactory estimations of power, it must be remembered that Bond’s expression was derived using a tumbling mill where the forces of comminution are not quite the same as that in jaw crushers.
