High-Performance Pellet Machine
WOOD PELLET MILL
WORKING PRINCIPLE & APPLICATIONS
Wood pellet mills transform wood and wood-based waste into dense, uniform pellets, widely used for heating, power generation, and other biomass energy applications. They provide an efficient, clean, and environmentally friendly energy solution.

Working Principle
Crushed raw materials are fed into the wood pellet machine, where they are compressed by the ring die and rollers into dense, uniform pellets. This efficiently converts loose biomass into high-density pellets.
Where can it be applied?

Heating Fuel
Produces clean-burning pellets for heating, offering an eco-friendly alternative to coal.

Biomass Power Generation
Pellets can generate heat for electricity production in biomass power plants.

Animal Bedding
Highly absorbent pellets help reduce odor, ideal for animal bedding.

Organic Fertilizer
Can be mixed with crop residues and manure for organic fertilizer production.

MODELS,RAW MATERIALS & PELLETIZING PROCESS
WOOD PELLET MILL MODELS
The wood pellet making machine series offers six models, covering small, medium, and large production lines to meet a variety of production needs.
SUITABLE RAW MATERIALS & PELLETIZING PROCESS
Here is an overview of the main raw materials compatible with our wood pellet machines and the pelletizing process.

Logs
Untreated logs can be chipped into thin pieces for further crushing or direct pellet production.

Wood Blocks
Wood blocks are processed into uniform sawdust, ready for pelletizing.

Sawdust
Easily processed, sawdust can be directly used for pellet production.

Wood Shavings
Typically sourced from wood processing, suitable for direct pellet production.

Crushing
Raw materials are crushed into 3–5 mm pieces for uniform pelletizing.

Drying
Materials are dried to 13%–18% moisture to ensure pellet quality.

Pelletizing
Dried materials are compressed into dense pellets by the ring die and rollers.

Cooling & Screening
Pellets are cooled and screened to prevent sticking and ensure uniform size.

FREQUENTLY ASKED QUESTIONS
Choosing the right equipment requires careful consideration. If you have any questions about RICHI wood pellet mills, feel free to leave your contact information. Our technical consultants will be happy to assist you.
What raw materials can be used in a wood pellet machine?
Wood pellet mills can process various biomass materials such as logs, wood blocks, sawdust, wood shavings, straw, corn stalks, and peanut shells. RICHI machines are highly adaptable and can handle different materials to meet diverse production needs.
How can pellet quality be ensured?
Pellet quality mainly depends on raw material moisture, pellet density, and uniformity. Materials should be crushed and dried before pelletizing, with moisture typically controlled at 13–18%. RICHI machines use high-precision ring dies and rollers, and pellets are cooled and screened after production to ensure stable and high-quality pellets.
Is maintenance complicated?
Maintenance is simple and cost-effective. RICHI machines use wear-resistant components and feature overload protection to ensure stable operation and extend service life. Regular inspection and replacement of wear parts help maintain long-term performance.
What is the production capacity of a wood pellet machine?
The capacity of a single RICHI wood pellet machine typically ranges from 0.2-4 tons per hour, depending on the model and raw materials used.
How is raw material moisture adjusted?
Moisture content is usually controlled with a dryer to maintain 13–18% moisture. If materials are too dry, a small amount of water can be added to achieve the proper level.
