Description

Technical Field

[0001] The utility model relates to the technical field of biomass particles, in particular to a biomass raw material chopping device. Background Art

[0002] Biomass pellets are an innovative energy solution that comes from the reuse of agricultural and forestry waste, such as rice husks, corn cobs, peanut shells, etc. These materials that might have been discarded are converted into particles of consistent size and shape through a series of processing steps including crushing, mixing, compression and drying. The diameter of these particles is usually in the range of 6 to 10 mm, and the length is about twice the diameter. They have a low crushing rate and moisture content, as well as low ash, sulfur, chlorine and nitrogen content. In the process of processing biomass pellet raw materials, a biomass raw material shredding device is required to shred the raw materials; however, since the raw materials are usually of different lengths, if the material reaching the feed roller is a large piece of material, it is easy to cause internal blockage after being fed into the shredding device through the feed roller, resulting in equipment shutdown, which seriously affects production efficiency.
