[0025] Preferably, the screw 10 is composed of a first threaded rod segment 33, a tapered threaded rod segment 34, and a second threaded rod segment 35.

[0033] In a specific implementation, the material is filled into the inner cavity of the screw outer tube sleeve 31 from the material bin 11, and the main motor 21 and the worm fan 17 are started through an electrical control switch (used to control the start and stop of the worm fan 17 and the main motor 21, and the common prior art in this field is not repeated here), so that the material is displaced along the guide direction of the spiral blade of the screw 10 under the action of the screw 10, and at the same time, air is filled into the screw outer tube sleeve 31 under the action of the worm fan 17 to mix the material and air, so that the blades of the screw 10 rotate to move the material. Extrusion can achieve uniform and rapid crushing. Compared with the existing technology, such pneumatic layout design can effectively reduce the phenomenon of agglomeration and clogging. At the same time, the material is more refined and the energy consumption is lower. In addition, compared with the centralized air supply in the existing technology, the interval air intake layout of this device effectively reduces vibration and noise, which is beneficial to the stability of the equipment. In addition, the mixing ratio of material and air is more reasonable. Compared with the traditional cylindrical cavity, this device adopts the design of a columnar crushing cavity and makes the crushing cavity gradually smaller through the gradual diameter of the screw 10, so that the material is gradually refined from the initial end to the outlet end and is conducive to heat dissipation to avoid heat accumulation.

[0034] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners.
