[0027] In practice, the drive motor 905 is started to drive the spur gear 904 to rotate. The spur gear 904 drives the internal gear ring 903 to rotate against the inner wall of the circular shell 2. The internal gear ring 903 drives the screen cylinder 901 to rotate. Smaller materials pass through the screen cylinder 901 and fall into the collection box 3. Larger materials are blocked by the screen plate 902 and fall into the two sets of crushing rollers 7 through the gap between the two sets of arc-shaped partitions 8 for further crushing, so that the crusher can circulate and crush.

[0028] See Figure 1 and Figure 5 It is known that the feeding mechanism 10 includes: a feeding port 1001, a feeding hopper 1002, a sector block 1003, and a hydraulic rod 1004.

The torque motor 5 is activated to drive the large gear 6 and the crushing roller 7 to rotate. The large gear 6 drives another set of large gears 6 and the crushing roller 7 to rotate, crushing the material. The drive motor 905 drives the screen cylinder 901 to rotate. Smaller materials pass through the screen cylinder 901 and enter the support base 1, falling into the collection box 3 for collection. Larger materials are pushed by the screen plate 902 onto the two sets of crushing rollers 7 for further crushing. This cycle continues until the collection box 3 is pulled out from the support base 1, and the crushed material is removed. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0031] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
