Product Description

The wood pellet machine is one of the products in the biomass energy pellet forming equipment series. It excels in energy-saving by turning straw waste into treasure, helping us solve the problem of handling or processing agricultural and forestry waste such as corn stalks, cotton stalks, rice straw, wood bran, wood flour, wood chips, peanut shells, and rice husks, which are commonly found in rural areas.

The biomass fuel pellet machine not only changes the physical form of these raw materials but also alters the internal molecular binding, which is the core aspect. This process not only reduces volume but also increases the combustion value. Fuel pellet machines address the social challenge of “double prohibition” on agricultural and forestry waste crop stalks and urban plant waste, effectively improving their comprehensive utilization rate. They also provide environmentally friendly and innovative fuel for industrial production, biomass power generation, restaurants, hotels, and residential use. The emergence of biomass fuel pellet machines enables more efficient utilization of biomass energy.

The wood pellet machine compresses the pulverized raw material into cylindrical fuel. The material does not need to add any additives or binders during processing.The raw material enters the screw feeder at an adjustable speed, and then it is transferred into a rotating ring die by a forced feeder. Final the wood pellet is come out from the hole of ring die, through the pressure between ring die and rollers.

Raw Material

Various common agricultural and forestry wastes with low utilization rates and easy pollution, such as wheat straw, cotton stalks, corn stalks, peanut shells, miscellaneous wood, wood chips, corn cobs, larch sawdust, and rice husks, can be processed into high-value biomass fuel. This promotes the use of clean energy and the development of a low-carbon economy. The development of biomass fuel has significant economic, social, and environmental benefits. Its application not only protects the environment and mitigates climate change but also promotes the extension of the agricultural industry chain.

wood pellet Raw Material


  1. Energy-saving: By utilizing rotational kinetic energy and increasing the effective lever arm, the machine can achieve a production rate of 4.5-5 tons per hour while saving over 45% of energy .
  2. Stability: The main machine weighs 14 tons and is made of integral alloy forged parts. The synchronous motor, along with the enlarged synchronous wheel, provides a large torque and rotational inertia, ensuring stable operation without blockages .
  3. Strong adaptability: The machine is capable of compressing different materials and even materials with high moisture content .
  4. Low maintenance cost: The roller only requires oiling once every 500 hours of operation, resulting in low maintenance expenses .
  5. Extended warranty: The chassis, main shaft, hollow shaft, gears, and synchronous motor are all covered by a two-year warranty, providing customers with an extended period of quality assurance .

Whole Production Line

A complete wood pellet production line includes crushing, drying, pelletizing, and packaging units. 

  1. Crushing: Wood blocks, wood chips, or other wood materials are uniformly crushed. This can be done using a wood crusher or shredder to reduce the size of the wood into smaller pieces.
  2. Drying: The crushed wood material is then fed into a drying machine drum through a conveyor belt. The drying process quickly reduces the moisture content of the material to around 12% to 15%. This is important for ensuring the quality of the final wood pellets.
  3. Pelletizing: Once the wood material is dried, it is then fed into a pellet mill. The pellet mill compresses the material under high pressure and heat, forming it into small cylindrical pellets. The pellets are then extruded from the pellet mill.
  4. Packaging: The pellets are discharged from the pellet mill and can be directly connected to a conveyor belt that leads to an automatic packaging machine. The packaging machine packages the pellets into bags

Advantages of Using Wood Pellet Machine

1.Abundant raw material supply:

Wood pellet machines and straw pellet machines mainly target waste wood chips and straw, which are the most abundant and urgently in need of processing . Construction waste, household waste, and the furniture industry generate large quantities of waste wood materials every moment. If these waste wood materials are directly discarded, it would not only pollute the environment but also waste renewable resources.

Additionally, straw is produced in large quantities every autumn. In the past, people used to burn straw directly, resulting in resource waste and significant environmental pollution. The treatment of crop straw has always been a concern for the government at both the national and local levels. In such circumstances, a machine that can process wood chips and straw, turning them into valuable resources, becomes particularly important. The significance of wood pellet machines and straw pellet machines becomes apparent.

2.Increasing demand for wood pellet machines:

With the rising prices of food, previously discarded crops can be processed using wood pellet machines and straw pellet machines to become animal feed. Additionally, wood pellets or straw pellets processed using wood pellet machines or straw pellet machines can be directly sent to power plants as a substitute for coal, serving as a new source of energy. This significantly reduces costs and is increasingly recognized by customers.
