In industrial vibrating screen work, to effectively screen a large number of particles so that the particles can effectively pass through the screen surface, the screen plate is usually high-frequency vibration to produce far more than gravity several times the peak of the acceleration .
Recent studies have used empirical validation and discrete element modeling to validate the screening efficiency of vibrating screens, but these studies are usually limited to the efficiency analysis of different parameters for a specific screen plate screen, and no more general model has been developed for predicting screening efficiency [2, 32].
At present, the more widely used commercial software are PFC2D, PFC3D, EDEM, and so on, among which EDEM has more outstanding stability advantages in large-scale particle motion calculation and is most widely used in vibrating screening. Commercial discrete element software is more convenient to apply.
At present, the hyperellipsoidal particle model is less used in the field of industrial vibrating screens, but with the theoretical research on the hyperellipsoidal model and the further improvement of the contact model, the advantages of the hyperellipsoidal model in the field of sphere-like simulation will be reflected.
