Korman et al. (Korman et al., 2015) measured power consumption of jaw crusher during crushing of rocks such as dolomite, limestone, spilite and diabase rocks and obtained similar trends, i.e higher the strength of the rock, higher the crushing energy. It is worthy to note that the crushing concrete specimens with 40 MPa took more time than ...

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.
