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 Rittinger’s or Stadler’s.) Our difficulty lies in ...

Relationships between comminution energy and product size for a magnetite ore [4] where E is the net specific energy; x f and x p are the feed and product size indices, respectively, and K3 is a constant. Hukki (1962) evaluated these energy-size relationships

Equation (11.2) is a statement of Kick's 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
