Technical Field
[0001] The utility model relates to the technical field of biomass particle raw material processing, in particular to a biomass particle raw material cutting and crushing device. Background Art
[0002] Biomass pellet fuel refers to a new type of clean fuel that uses agricultural and forestry waste as raw materials and is made into pellets through processes such as crushing, mixing, and extrusion. Raw materials generally include wood, sawdust, straw, rice straw, rice husks, peanut shells, and corn cobs. When processed by a crushing device, larger raw materials such as wood, straw, rice straw, and corn cobs have higher crushing requirements for the crushing device. Generally, they need to be broken into small pieces before being crushed. At present, the crushing method adopted by small factories is still to crush the material through the crushing equipment first and then enter the crushing equipment for crushing. This method is cumbersome and inconvenient for the matching assembly of the input and output between the crushing equipment and the crushing equipment, and the overall equipment occupies a relatively large area. For this reason, a medium-sized all-in-one machine that can integrate crushing and crushing is needed to complete the processing of biomass pellet fuel raw materials. Utility Model Content
