    Equation (113) is known as Rittinger's Law As the specific surface of a particle, the surface area per unit mass, is proportional to 1/L, eqn (113) postulates that the energy required to reduce L for a mass of particles from 10 cm to 5 cm would be the same as that required to reduce, for example, the same mass of 5 mm particles down to 47 mm This is a very much smaller reduction, in terms of energy per unit mass for the smaller particles, than that predicted by Kick's Law

    Rittinger (1867) stated that the energy required for size reduction is proportional to the new surface area generated Since the specific surface area is inversely proportional to the particle size, Rittinger’s hypothesis can be written in the following form: [2] where Eis the net specific energy; x

    For efficient grinding, the energy applied to the material should exceed, by as small a margin as possible, the minimum energy needed to rupture the material Excess energy is lost as heat and this loss should be kept as low as practicable The important factors to be studied in the grinding process are the amount of energy used and
