Crushing And The Law. I happen to be one of those who believe that rittinger probably meant what he said when he wrote what stadler has quoted, the increase of the surfaces exposed is directly proportional to the force required for reducing and therefore also to the work absorbed in effecting the separations.The italics are now mine instead of rittingers or stadlers.Our difficulty lies in.

where Wi is the Bond Work Index, again in energy per unit mass terms. The index is defined as the energy required to crush from infinite size down to 100 m, hence the 10 inside the brackets. Bonds Work Index values, in kWh per short ton i.e. 2000 lbs or 907 kg, roughly follow the Mohs scale of hardness, see Table 11.1.
