Abstract:

In order to study particle segregation in the rotating drum, the movement of particles is studied by theoretical deduction and numerical simulation. According to the theoretical deduction, particles near the end wall are lifted higher by the friction of the end wall, which leads to small particles gathering in the middle of the drum. The model of particle motion is established based on the discrete element method. It can be shown from the simulation results that the particles accumulated higher near the end wall, which is consistent with the theoretical deduction. In addition, the effects from the aspects of the relative friction between particles, the friction between the end wall and particle, the drum aspect ratio and the rotation speed were explored by the simulation. From the simulation results, it can be pointed out that the friction of the end wall has a decisive influence on the axial segregation of the particles, and the other factors merely affect the accumulate forms of particles.
