Example Embodiment
[0027] Example 1
[0028] like figure 1 As shown in the figure, this embodiment provides a multi-stage processing system for crop straw, including a pretreatment machine for cutting straw raw materials into strips, a pulverizer 1 is arranged below the pretreatment machine, and a pulverizer 1 is arranged on the top of the pulverizer 1. The feeding hopper 2 near the discharge end of the pretreatment machine is provided with at least two sets of crushing mechanisms 3 arranged from top to bottom inside the crusher 1. The crushing mechanisms 3 are all located directly under the feeding hopper 2. Press machine 4.
[0029] In this embodiment, the long straw material is first cut into short strips by the pretreatment machine, which is convenient for later processing. Under the action of the mechanism, the straw material is pulverized into small particles. During the pulverization process, the crude fiber in the straw can be fully destroyed, and the crude fiber content of the straw c...
