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.

Primary size reduction with Jaw Crushers
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
