Study of the Effect of Liquid on Mixing Process for Size-Type Binary Particulate Systems By DEM Simulation

摘要

The discrete-element method(DEM) was employed to simulate the mixing and segregation process for size-type binary particulate systems in a rotating horizontal drum for dry particulate systems and wet particulate systems. The effect of interstitial liquid on the mixing and segregation process were studied. The simulation results showed that the liquid bridge between particles play an important role in mixing and segregation process, as a result, segregation may be mitigated and mixing may be enhanced. To assess the accuracy of the simulation result, some comparisons were made with the experimental results in the literature.
