In the grinding process, materials are reduced in size by fracturing them. In the process, the material is stressed by the A Rittinger's Law (2) As the specific surface of a particle (the surface area per unit mass) is proportional to 1/L, equation (2) postulates that the Rittinger's Law fits the experimental data better. 3) Bond has(310b) Teaching Old Laws New Tricks Specific Energy,Rittinger (1867), Kick (1885) and Bond (1952) all proposed empirical laws to estimate the specific energy requirement for accomplishing a given extent of size reduction expressed in terms of the initial and final particle size (length dimension) and an empirical constant.
