After stirring, the materials fall into the outside of the limiting ring and the inside of the crushing and mixing barrel due to their own weight. Subsequently, as the crushing and mixing barrel rotates on the upper end of the connecting plate, the stirred materials are driven to contact the two pairs of crushing rollers and the rotating stirring roller. As the crushing and mixing barrel continues to rotate, the materials repeatedly contact the crushing rollers, and after being crushed by the crushing rollers, they are stirred by the stirring rollers. The materials are crushed while being stirred and mixed.
