Wood pellet machines are core equipment that process agricultural and forestry waste, such as sawdust, straw, and branches, into standardized pellet fuel through a series of processes, including crushing, extrusion, and molding. These machines are widely used in biomass energy, livestock bedding, and gardening substrates.
Utilizing precise transmission and wear-resistant molds, these machines can reliably process a variety of wood materials. The resulting pellets have high density and a stable calorific value. This not only enables the resource utilization of agricultural and forestry waste, reduces environmental pollution, but also provides a high-quality solution for clean energy alternatives. Furthermore, the equipment features automated operation and easy maintenance, adapting to varying production capacity requirements, helping businesses reduce costs and increase efficiency, while promoting the development of a green, circular economy.
Crushing: Crush raw materials such as straw, wood chips, and dead branches into small particles of 3-5 mm to ensure uniform feeding.
Drying: Control the moisture content of raw materials at 10%-15% through a dryer to avoid cracking and looseness after forming.
Mixing (Optional): Add binders or other auxiliary materials as needed to improve particle adhesion.
Feeding: The pretreated raw materials are uniformly fed into the main engine extrusion chamber through the silo and screw feeder.
High-temperature and High-pressure Extrusion: Under the extrusion of press rollers and ring dies (or flat dies), the temperature of raw materials rises to 100-120℃, the fiber structure is reorganized and pressed into die holes.
Pellet Cutting: The continuous rod-shaped materials extruded from the die holes are cut into pellets of set length (usually 6-10 mm) by cutters.
Cooling: The newly formed pellets have high temperature and slightly high moisture content. They are cooled to room temperature by a cooler (mainly air-cooled) to improve stability.
Screening: Unqualified crushed particles and powder are separated by a vibrating screen, and qualified pellets enter the finished product warehouse.
Packaging: Weigh and pack according to specifications for easy storage and transportation.
