How the Wood Pellet Mill Works
The wood pellet mill essentially transforms loose wood waste into dense pellets through a process of compression and shaping. The core of the entire process involves pre-treatment first, then extrusion, and finally shaping and cutting.
Below is a detailed step-by-step explanation:
First , the crushed biomass material is evenly fed into the pelletizing chamber through a feeder equipped with a frequency conversion speed regulation device. This allows precise control of the feeding rate, ensuring uniform material entry and effectively preventing equipment overload due to excessive feeding or idle running caused by insufficient feeding. An anti-bridging bin integrated above the feeder continuously stirs the material to prevent clogging and blockages.
Second , it’s the core process of the wood pellet production — extrusion and molding. After the wood raw material enters the pelletizing chamber, it is compressed by high-speed rotating rollers and forced into the small holes of the ring die. These holes shape the wood material into elongated strips.
Third , after the wood shavings are extruded through the ring die holes under the pressure of the rollers, a cutting device located outside the ring die trims the extruded strips into uniform pellets according to the preset length.
The newly formed pellets, which are at a high temperature, are conveyed to cooling equipment to reduce them to room temperature. This prevents mold formation or clumping caused by stacking hot pellets. Finally, the pellets pass through a screening device to remove fine powder.

Application of Pellets Produced by Wood pellet mill
Wood pellet mill can process any agricultural and forestry waste into biomass pellets that can be burned as an alternative to coal and natural gas. These biomass pellets can not only serve as an environmentally friendly heating fuel but are also used in multiple fields such as energy, industry, and agriculture. They represent a successful model of biomass energy utilization.
Heating and Warm Supply
Wood pellets are used to provide heating and hot water for households, schools, hotels, factories, and other large-scale facilities. Using wood pellets as the fuel for heating systems not only replaces traditional fossil fuels but also provides continuous and stable heating, combining economic efficiency with environmental friendliness.
Industrial Boiler Fuel
Many factories requiring steam or thermal energy (such as textile mills, chemical plants, and food processing plants) can use wood pellets as an eco-friendly alternative to coal, crude oil, or natural gas. This helps reduce operating costs and comply with environmental regulations.
Power Generation
Wood pellets serve as a primary fuel in large-scale power plants. Through direct combustion or co-firing, they generate steam to drive turbines for electricity production. This represents an important renewable energy generation method that helps reduce reliance on fossil fuels and lower carbon emissions.
Animal Bedding
Wood pellets offer excellent absorbency and odor control, making them suitable for use as bedding in horse stables, chicken coops, and enclosures for hamsters and rabbits. They effectively absorb urine, maintain a dry and hygienic environment, reduce odors and bacterial growth, and improve the living conditions for animals.
A complete Wood Pellet Production Line
A complete wood pellet production line covers all processing stages from raw materials to finished pellets, including: Chipping Stage, Crushing Stage, Drying Stage, Buffer Storage Stage, Pelletizing Stage, Cooling Stage, Packaging Stage.
Chipping
01
This stage is primarily designed for the chipping processing of large-sized raw materials such as timber and wood panels.
Crushing
02
This stage utilizes a water-drop type hammer mill to pulverize the raw materials into fine powder. The crushed material is then extracted from the hammer mill by airflow, enters a cyclone for dust removal and collection, and is finally conveyed to a buffer storage bin.
Drying
03
The crushed material may have high moisture content and requires drying. A hot air furnace generates hot air, which is conveyed to the drying cylinder by an induced draft fan. During rotation, the drying cylinder continuously lifts and disperses the material, ensuring full contact with the hot air for effective drying.
Buffer Storage
04
The dried material is conveyed via belt and auger to a storage bin for temporary buffering. This allows the moisture within the dried material to redistribute evenly in the bin, ensuring uniform moisture content and facilitating stable operation of the pellet mill during the pelletizing process.
Pelletizing
05
The crushed material is fed into the feeder, which is equipped with an anti-bridging bin to continuously stir the material and prevent agglomeration. Through the forced feeder, the raw material is forcefully conveyed into the pelletizing chamber for pellet formation.
Cooling
06
The newly formed pellets are at a high temperature and prone to mold or clumping, thus requiring cooling. Inside the cooling bin, the pellets are cooled to room temperature through a counter-current air circulation system. The bottom of the cooling bin is equipped with a simple screen, and the cooled pellets undergo further screening to improve their quality and ensure they meet standards.
Packaging
07
The screened finished pellets are conveyed via a steep-angle belt conveyor to the finished product bin. Below the bin, an automatic weighing system for ton bags is installed to package the pellets according to preset weights.
