AB  - In order to control the accumulation of <i>SiC</i> ceramic particles on the wall of the rotating chamber in the frame of a dry granulation process, the effect of the wall reverse speed on the mixing process is investigated. In particular, an Euler-Euler two-phase flow model is used to analyze the dynamics of both <i>SiC</i> particles and air. The numerical results show that by setting a certain reverse rotating speed of the rotating chamber, the accumulation of <i>SiC</i> particles on the wall can be improved, i.e., their direction of motion in proximity to the wall can be changed and particles can be forced to re-join the granulation process. Experimental tests conducted to verify the reliability of the numerical findings, demonstrate that when the reverse rotating speed of the rotating chamber is 4 r/min, the sphericity of <i>SiC</i> particles in the rotating chamber is the highest and the fluidity is the best possible one.
