This method improves the cumbersomeness of traditional metallurgical powder mixing, which requires manual irregular addition of different powder materials for mixing. While stirring at the output end of the motor, different powder materials on four material barrels can be fed and stirred in a timely and quantitative manner, thereby improving the simplicity of automatic feeding and mixing of powder materials, reducing the time-consuming and labor-intensive manual filling of traditional materials, and thus improving the efficiency of metallurgical powder mixing to a certain extent.
