Numerical Simulation of Granular Mixing in Conical Mixer with Different Angles Using Discrete Element Method

Granular mixing process is necessary for operation in many industries such as food, pharmaceutical and cosmetic industries. Although the materials are almost first stage production process, it can affect quality cost of final product. They choosing a suitable mixer that may reduce energy consumption. A static device widely used to mix Because phenomena very complex, proper design still needs be studied. In this work, we simulate pro-cess granular conical mixer. We assume two types gran-ular solid with same size flowing The discrete Element Method (DEM) applied obtain numerical solutions mathematical model. This work aims use coordinate index compare effectiveness from mixers different angles, including 15o, 30o, 45o, 60o. results show highest number occurs an angle . These imply best quality.
