Numerical simulation of the mixing process of the continuous mixer using the discrete element method

Abstract

Abstract. This paper used the discrete element method to simulate the continuous mixing process and defined the time that the particles participated in mixing in the mixer was defined as the effective mixing time. The effects of different structures and rotational speeds on the mixing efficiency were studied by using the effective mixing time and dispersion coefficients, the function of the rotation speed and effective mixing time be fitted at the same time. In this research also found the appropriate outlet and rotation speed to make the mixer has a high mixing efficiency which was used in this paper. The research results can provide basis and reference for structural design of continuous mixer.
