The mixing processes of carbon spherical particles in 3-D tumbler at five typical rotating speeds are simulated by using the open source software OpenFOAM utilizing soft sphere model of discrete element method. The evolution of particle mixing is investigated, and the structural characteristics of particle mixing in different regimes are illustrated. Moreover, with the help of the information entropy and a series of new mixing indexes, which are the difference value functions, we quantitatively analyze the influence of rotating velocity on particle mixing characteristics.
