[0002] Biomass pellets are a renewable energy source that is usually compressed and processed to convert compressed materials into granular materials. They come from a wide range of sources, including wood, waste, plant and animal byproducts, etc. Compared with traditional fuels such as coal and natural gas, biomass pellets have the advantages of being renewable, clean, efficient, and low-emission.

[0003] The manufacturing process of biomass pellets is usually carried out at room temperature, using rollers and ring dies to cold-densely mold crushed biomass straw, forestry waste and other raw materials. The density of the raw materials is generally 0.1~0.13t / m³, and the density of the molded pellets can reach 1.1~1.3t / m³, which makes biomass pellets more convenient to store and transport, and greatly improves the combustion performance of biomass.

[0004] After the wood crusher in the prior art has completed the wood crushing, the wood usually falls directly downward through the crushing rod area to the recovery area below, and the height of the recovery area is usually fixed.
