Abstract: type mixer is make up of transmission components, electrical parts and control components. The body is the two cylinder structure. The body frame by the mixing chamber and the stander. Transmission components are the motor, belt, reducer, and etc. . The control components are contactors, relays and control switches. The design is needed to design the structure of the body-size mixer, and to select the reducer, drive shaft, pulley size, belt and options. In the process of designing, I used a new calculation principle and motor control devices. And comparing with the selected demonstration motor, the motor options to ensure compliance with design requirements. The mixer is favorable, low cost and wide application.
Key word: type mixer, belt transmission ,reducer, coupling, the motor
