Vibration amplitude can be adjusted by adjusting nut.

In a word, the vertical multi-stage straw pulverizer of the present invention has reasonable structure, convenient operation and high production efficiency. Straw is inserted from the evenly distributed support space between the top cover and the upper port of the outer casing, and is roughly cut and crushed through the upper cylinder, the middle cylinder and the inner layer of the bottom cylinder, and finally becomes straw crushed particles and falls into the blanking material. groove. The crushed straw particles reach 3-7mm, and the production rate is 1 ton/hour.
