Abstract
Despite the wide research of powder and solid mixing in science and industry, a majority of researches focus on numerical simulation. Theory on the actual mixing of solid particles in 3D rotary drums is needed. In this work, the axial segregation of binary spherical granular particle is studied experimentally in a 3D tumbler to find the effect of key outer parameters on the mixing results. Experiment results indicate the outer parameter-rotational speed will have significant effect on axial segregation and there is some kind of competition between axial segregation and radial segregation. In addition, The initial loading method has noting to do with axial segregation. These results will provide guidance for particle mixing in cylinder mixer.
