The airflow generated by the suction draws the powder inside the crushing box into the air ring box through the powder extraction structure. The airflow then drives the powder to move above the filter plate. The filter plate blocks the powder in the airflow and filters it in the vertical holes above the filter plate. Then, during the rotation of the air ring box and the ring plate, the filter plate and the cylinder are driven to rotate relative to the ring plate and the vertical holes, so that the vertical holes above the filter plate are connected with the adjacent cylinders during the rotation of the ring plate.

When the breathable circular wheel rotates around the axis of the crushing box, the breathable circular wheel swings up and down, and the breathable circular wheel rotates relative to the polygonal ring, the angle range of the air flow drawn into the interior by the breathable circular wheel is increased, so that the powder in the crushing box can be fully drawn into the air ring box.

[0017] 3. The present invention provides a supporting plate, a leakage hole and a scraper plate. When multiple crushing tool holders crush the raw materials, the supporting plate supports the fallen raw materials, so that the crushing tool holders can continue to fully crush the raw materials in the supporting plate, and the scraper plate scrapes and stirs the inside of the supporting plate to continuously change the position of the raw materials. After being crushed to a size that matches the inner diameter of the leakage hole, the raw materials fall into the adjacent supporting plate below, so that the raw materials can be fully crushed.
