    Equation 11.2 is a statement of Kicks Law. It implies that the specific energy required to crush a material, for example from 10cm down to 5cm, is the same as the energy required to crush the same material from 5mm to 2.5 mm. Rittinger, on the other hand, assumed that the energy required for size reduction is directly
