wood pellet extruder machine
Wood pellet extruder machine efficiently processes sawdust, wood chips, and agricultural waste into high-density fuel pellets. Ideal for eco-friendly biomass energy production with stable performance and low energy consumption.
Product Overview of wood pellet extruder
The wood pellet extruder machine is a mechanical device that processes powdered raw materials such as logs, sawdust, and branches into uniform-sized chips through physical compression and high-temperature molding techniques.
Its working principle is to first squeeze the raw materials through a circular mold, and then precisely cut them to the desired length using a cutting device.
The pellets produced by the wood pellet extruders have a wide range of applications, including use as cat litter, feed for large-scale livestock farms, and heating fuel for residential and industrial power generation.
Additionally, this pellet fuel boasts excellent refractory properties, high calorific value, easy storage and transportation, and low pollution during combustion, making it an environmentally friendly energy option.
It uses heating and extrusion to compress the raw materials into pellets of a specific shape and size, and is commonly used for manufacturing fuel pellets or cat litter.
- During the work process, the raw materials are first crushed and dried, and then evenly sent into the feed inlet of the machine.
- Inside the machine, there is a screw that rotates at high speed under the drive of the motor, pushing the raw materials forward.
- As the screw rotates, the temperature of the raw materials rises due to compression and friction, and some of the moisture evaporates, making them become soft and viscous.
- Then, the softened raw materials are forcefully pressed into the mold through the mold holes and formed by extrusion.
- The extruded pellets will pass through the cooling device for cooling, and then be cut into a uniform length to complete the entire forming process.
The entire process does not require the addition of any extra adhesives. The lignin in the raw materials is used as a natural adhesive, which is both environmentally friendly and highly efficient.

- Project Country: Congo
- Application Project Name: 1-1.2T/H Wood Pellet Production Line in Congo
- Raw Materials: Wood chips and moisture sawdust.
- Main Equipment Included: Wood crusher, shifter, dryer, storage bin, wood chip pellet machine, cooler.
- Project Background: The wood processing industry in Congo is highly developed, generating a large amount of waste, such as wood chips and wet sawdust. This not only leads to waste of resources but also brings environmental pressure. To achieve the resource utilization of the waste, local enterprises planned and constructed this wood chip pellet production line with a capacity of 1 – 1.2 tons per hour. By using professional equipment, the waste was transformed into wood pellets of 1 – 3 millimeters in size, meeting the needs of energy and animal husbandry.

What types of raw materials can a wood pellet extruder machine process?
This machine is quite versatile and can process a wide range of biomass materials.
It includes raw logs, sawdust, wood chips, wood shavings, as well as agricultural residues like straw, corn stalks, and crop husks. Some models are even designed to handle organic waste such as animal manure to produce organic fertilizer pellets.
When choosing a machine, it’s best to consider what type of raw materials you have to ensure optimal performance and pellet quality.
What is the ideal moisture content for raw materials used in pellet production?
The moisture content of your raw materials is very important for producing good quality pellets. Ideally, it should be between 12% and 18%.
If the material is too wet, it might clog the machine or cause the pellets to break apart easily. On the other hand, if it’s too dry, it can generate excessive dust and make it difficult for the pellets to stick together.
That’s why proper drying before feeding materials into the wood pellet extruder machine is crucial to get the best results. RICHI can also provide suitable drying equipment if required
Can the machine handle different pellet sizes?
Of course. Our equipment can produce pellets in sizes of 4-12mm and supports ring mold replacement. Customers typically choose pellet diameters between 6mm and 12mm, and RICHI can also be customized according to your needs or fuel standards.
Can wood pellet extruder machine be integrated into a complete production line?
Absolutely! These machines are often a core part of a complete wood pellet production line that includes steps like raw material cleaning, crushing, drying, cooling, and packaging. When all these processes are combined, production runs more smoothly and efficiently, and the final pellets are of higher quality. We can help you design a custom production line tailored to your specific needs.
