Study on DEM parameter calibration and wear characteristics of vanadium-titanium magnetite pellets

In this work, DEM parameters of ellipsoid pellets were measured by means of self-made experimental device. On this basis, the effects of different roasting temperatures and equivalent diameters on DEM parameters of pellets were analyzed. In addition, the wear rate and movement velocity of different pellets in the drum were measured and extracted. Then, the applicability of measured DEM parameters of pellets is discussed. The results show that...
