The MLCC electronic materials are used to make many industrial parts, for instance, such as smart phone, radio, LCD TV and so on. The screen ways and the rotor ways are known as methods that form electrode in MLCC. In these days, rotor ways have been frequently utilized because of its stability of quality. In this study, mixing characteristics for the inside of barrel of planetary mixer driver were investigated by numerical analysis using k-ε model of unsteady state, including effects for rotation and revolution. As the results, it showed that the flow of radius direction was mixed with regular pattern depending on time, however, the flow of longitudinal direction was mixed with same pattern regardless of time.
