Fuel Pellet Mill
RICHI fuel pellet mills compress forestry and agricultural residues such as sawdust, wood shavings, straw, rice husks and peanut shells into solid fuel pellets. They are widely applied for residential heating, boiler rooms and biomass power plants, delivering much higher cost efficiency and cleaner combustion than burning loose raw materials directly.
According to different customer needs, RICHI designs different equipment models.
Fuel Pellet Machine
It is designed to produce commercial biomass fuel pellets from agricultural and forestry residues.
Finished fuel pellets
Fuel pellets made by the fuel pellet mill feature:
- High density and good durability: Dense pellets with low fines and minimal loss during storage and transportation.
- Stable combustion performance: Consistent calorific value and controllable ash content, suitable for boiler combustion and biomass power generation.
- Binder-free forming: Bonding depends on endogenous lignin activated by friction heat during extrusion. No chemical adhesives are added, qualifying it as clean biomass fuel.
Output:0.2-4.0 T/H
Finished Pellet Diameter:4.0-12.0 mm
According to different customer needs, RICHI designs different equipment models.
Equipment Structure of Fuel Pellet Machine
Variable Frequency Feeding System
Equipped with a stainless steel feeding bin and variable-speed screw feeder, it automatically adjusts feeding volume according to raw material characteristics and production capacity to avoid blockage. A built-in magnetic separator removes metal impurities, protecting core ring die and roller components and reducing equipment failures.
Optional Conditioning & Premixing Unit
This unit is optional and selectively configured according to raw material conditions. It is necessary for processing low-density, high-fiber, and hard-forming materials such as crop straw, rice husk, and palm EFB, as well as raw materials with unstable moisture content, while can be omitted for high-density, low-impurity wood sawdust and wood shavings with stable moisture.
Ring Die & Roller Press Assembly
The core molding unit adopts high-strength wear-resistant alloy ring die and thickened rollers, with customized compression ratios for wood, straw, shell and other biomass materials. Equipped with a quick-release structure, it enables fast die replacement and routine maintenance, minimizing downtime during formula switching.
Heavy-Duty Drive & Protection System
Configured with high-efficiency motors and heavy-duty gearboxes for stable power output and high transmission efficiency. Built-in overload protection, torque monitoring and fault alarm systems support 24-hour continuous stable operation.
Adjustable Pellet Cutting Mechanism
External high-speed adjustable cutters flexibly control pellet length by adjusting the gap with the ring die, delivering uniform, neat pellets with few fines.
According to different customer needs, RICHI designs different equipment models.

Supporting Production Line
RICHI’s complete equipment lineup protects and stabilizes your production line.
Raw Material Preprocessing
Bulk raw materials such as tree branches and crop straws are crushed into uniform fine particles that meet pelletizing standards. Meanwhile, stones, metal scraps and other foreign impurities are screened out completely, effectively protecting the ring die and rollers of the pellet mill from abrasion and damage.
Drying
Adjust raw material moisture to the optimal 12%–18% range for stable pellet forming. Wet straw, EFB and agro-residues require drying treatment; dry qualified sawdust can skip this procedure directly.
Pellet Forming
Qualified materials are delivered into the ring-die fuel pellet mill. Under high extrusion pressure and friction heat, the natural lignin inside biomass melts and bonds raw materials into dense, cylindrical fuel pellets.
Pellet Cooling
Newly extruded high-temperature pellets are cooled to room temperature, which stabilizes pellet hardness and density, reduces fine powder generation, and avoids mildew during storage and transportation.
Grading Screening
Broken pellets and unqualified fine powders are separated. All screened fine materials are recycled and reprocessed to improve the overall finished product yield.
Finished Product Packaging
Standard uniform fuel pellets are automatically weighed and sealed in bags, ready for storage, transportation and commercial sales.
RICHI equipment delivers reliable performance anywhere.

FAQs
Should you have any questions, RICHI will provide you with professional answers.
When is a conditioner necessary for my line?
Choose the conditioner for low-density, high-fiber materials like straw, rice husk and palm EFB. Stable, dry wood sawdust normally does not need it.
What standard sizes do finished fuel pellets come in?
Standard 6 mm and 8 mm. Custom sizes from 4 mm to 12 mm are available upon request.
Can RICHI supply the full turnkey pellet line instead of only the pellet mill host?
Yes. RICHI designs complete lines including crushing, screening, drying, pelletizing, cooling, grading and packing. Overseas packages cover installation, commissioning and spare parts.
What raw materials can this fuel pellet mill handle?
It works for most agroforestry biomass: sawdust, wood shavings, branches, corn/wheat straw, rice husk, peanut shell, palm shell, EFB, bamboo scraps and olive pomace.
