#### CHAPTER 11 SIZE REDUCTION NZIFST Home

Equation 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 postulates that the energy required to reduce L for a mass of particles from 10cm to 5cm would be the same as that required to reduce for example the same mass of 5mm particles down to This is a very much smaller reduction in terms of of energy per unit mass for the smaller particles than that predicted by Kick s Law
