Abstract：To research the effect of mixing and the continuity of access to materials, Fluent software k-ε turbulence model and Simple algorithm were used to simulate the internal flow of continuous particle materials blender. The mixing effect under the three different inlet position was analyzed. The results show that the best inlet position is located in the bottom of upper surface of the blender. In this case, the materials have a longer residence time, the materials are fully mixed. The amount of the material's inflow and outflow basically balance, which ensure the continuity of production.
