Claim 6:
7. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells according to claim 1, wherein the third-stage pneumatic impact micro pulverizing region comprises lower airflow guide pipes, lower spray nozzles, spiral crushing gratings and an inner lining layer, the lower airflow guide pipes are respectively connected with the lower spray nozzles, the lower spray nozzles are connected with a barrel, spray nozzle outlets are connected with the barrel in a penetrating way, the spiral crushing gratings are welded to a lower main shaft, providing high-speed collision on the finely crushed walnut shell particles, assisting in pulverization, tooth-shaped micro bulges are disposed on an inner surface of the inner lining layer, and the tooth-shaped micro bulges are adapted to engage with the finely crushed walnut shell particles carried by a high-speed airflow, thus effectuating pulverization through collision and violently rubbing.
