The installed power of a fragmentation unit is the sum of the energy required to drive it at no load and the energy required to fragment the material. While the former is constant for a given device, the latter varies with the flow rate and the characteristics of the material, before and after comminution.

It is possible to determine the characteristics of a fragmentation unit (dimensions, installed power, capacity, etc.) from empirical formulas and laboratory and/or pilot tests, but it is always advisable to contact the manufacturer to check the validity of the results and ensure the right choice of unit.
