A performance model for impact crushers
In his model, the particles can break either after impact with the hammer bars of the rotor or after collision with the internal walls of the crusher's chamber. The mass balance of this model is an extension of Eq. (2) and does not incorporate the possibility for further fragmentation of the debris issued from breakage of parent particles.

How to Ensure the Balance of the Rotor in a Hammer Crusher
At the same time, uneven wear of the hammer heads during operation is also a factor that affects rotor imbalance. When designing a hammer crusher, attention should be paid to ensuring that the dynamic load of the crusher does not exceed the allowable value. After the rotor is assembled, a balance test must be performed.
Modelling and simulation of particle breakage in impact crushers
In this formulation, both k 1 and k 2 depend on the crusher setting, which is a 'static' design variable. In impact crushers, the breakage probability depends mainly on the grain size and the kinetic impact energy (King and Bourgeois, 1993), which is clearly a dynamic variable. Therefore, we have to define another, more suitable ...
