[0002] The biomass particle granulator is a biomass energy pretreatment equipment. Mainly taking the biomass such as sawdust, straw, rice husk, tree bark and the like as raw materials, the biomass particle granulator is used for solidifying and shaping the biomass into high-density pellet fuels through pretreatment and processing. When the biomass particle granulator works, the motor drives the main shaft and the compression roller to rotate, and the material is fed into the granulator from the feeding port and is subjected to strong extrusion and friction between the compression roller and the ring die. Since the ring die is uniformly provided with a plurality of die holes, the material is extruded through the die holes under pressure to form columnar particles, which are then cut into pellet fuels of a certain length by the cutter.

However, it is found that there are still some raw materials that are not completely crushed in the actual processing, and the raw materials that are not completely crushed will affect the subsequent granulation quality. Therefore, in order to solve the above problems, the application provides a granulator with a crushing structure. CONTENT OF THE UTILITY MODEL

[0010] In summary, the present application has the following beneficial technical effects:
[0011] By designing the crushing and granulating assembly, when producing biological granules, the material injected through the injection opening is accumulated on the top of the partition plate. The rotation of the motor-driven rotating shaft drives the crushing blade, the compression roller and the bottom plate to rotate. The crushing blade crushes the material on the top of the partition plate, and the processed material falls into the forming frame through the through hole. The compression roller applies pressure to the material in the forming frame, so that the material is extruded from the plurality of forming holes. Finally, the bottom plate drives the plurality of scrapers to rotate, so that the scrapers remove the biological granules extruded from the forming holes. Compared with the prior art, this design can crush the material again before granulation processing, so that the raw material is more fine, thereby improving the processing quality of the biological granules.
