Particle-size reduction
Rittinger postulated that the energy required for particle-size reduction is directly proportional to the amount of new surface area created. (1) Where: CR = constant, kWh-m/ton. E = breakage energy per unit mass of feed, kWh/ton. df = particle size of feed, m. dp = particle size of final product, m.
