1. Select the type of agitator according to the process conditions, mixing purpose and requirements. When selecting the type of agitator, we should fully grasp the dynamic characteristics of the agitator and the causal relationship between the flow state of the agitator and various mixing purposes.
2. According to the determined type of agitator and the flow state of the agitator produced in the stirring process, the control requirements of the mixing room, settling speed and dispersion of the process, the motor power, stirring speed and agitator diameter are determined by experimental means or computer simulation design.
3. According to the motor power, speed and process conditions, select and determine the reducer model from the reducer selection table. If the reducer is selected according to the actual working torque, the actual working torque should be less than the allowable torque of the reducer.
