Biomass pellets are a type of fuel that uses rollers and ring dies to cold-densely mold crushed biomass straw, forestry waste and other raw materials. The following is the production process of biomass pellets:

  1. Raw material collection and preparation

  The production of biomass pellets first requires the collection of various biomass raw materials, such as sawdust, bark, branches, crop straw, etc. The raw materials need to be transported to the production workshop and undergo preliminary processing, such as removing impurities and crushing, to ensure the smooth progress of subsequent processes.

  2. Cutting and crushing

  After the raw materials enter the workshop, they pass through a dedicated raw material conveyor and enter the cutting or crushing stage after iron removal. The cutter is used to cut the raw materials into 15-20mm long needle-shaped and foam-shaped fragments, while the crusher is used to further reduce the size of the raw materials.

  3. Drying

  Drying is an important step in the production of biomass pellets. The cut or crushed raw materials need to be dried in a dryer to remove the moisture, which is crucial to ensure the quality and combustion performance of the pellets.

  4. Pellet Forming

  After drying, the raw materials pass through the wood chip pellet machine. Under the rotation of the pressing wheel and the action of the mold, the powdered materials form a continuous cylindrical solid body and finally form biomass pellets.

  5. Cooling and screening

  After the pellets leave the pellet machine, they need to be cooled by a cooler to reduce their temperature and remove the steam on the surface. Afterwards, the pellets enter the screening machine to screen out qualified products.

  As a new type of particulate fuel, biomass pellets have won wide recognition for their unique advantages; compared with traditional fuels, they not only have economic advantages but also environmental benefits, which fully meet the requirements of sustainable development.
