Plant dynamics is a complex phenomenon where correlation and casualization can be vague. To simulate plant dynamics mathematical models for every production unit, e.g. crushers, screens, conveyors, silos, etc., has to be created. The models describe the changes in flow and particle size of the material traveling through the plant.

A geometric model of rotors is established on the basis of the structure of vertical shaft impact crusher. The dynamic simulation of the rotor is carried out by using the discrete element software EDEM. At the same time, the correlation between the angle of the guide plate and the crushing performance of the crusher is studied systematically. …

Djordjevic et al. (2003) simulated the particle movement and calculated the velocity and energy distribution of collision in two types of impact crusher by applying the DEM technique: the vertical shaft crusher and the horizontal shaft mill. Experimental data of the hammer mill were used to verify the DEM simulation results.
