Working process of complete wood pellet plant
The production process of the wood pellet production is: pretreatment → crushing → drying → granulation → cooling and screening → packaging
1. Raw Material Collection & Pre-treatment
This production line is designed to process various biomass materials including logs, branches, and wood processing residues (such as shavings, sawdust, and trimmings). For larger, harder logs or blocks, the system first uses a drum chipper to perform preliminary crushing, cutting them into 2-3cm wood chips. Operators can adjust blade rotation speed and feed rate according to material type and hardness, ensuring optimal chip quality while maintaining stable equipment operation.
2. Crushing Section
The wood chips after cutting and the uncut wood raw materials, such as branches, wood chips, waste scraps, will be sent to the wood chip hammer mill for further processing, so that the wood chips can be crushed into small wood chips of 3-5mm to meet the requirements of granulation.
3. Drying Section
In order to ensure the molding rate and quality of wood pellets in the complete wood pellet plant, the moisture content of raw materials must be controlled between 12%-18%. A rotary drum dryer is used to fully contact the raw materials with hot air, evaporating the moisture. By controlling temperature and drum rotation speed, rapid, uniform, and stable drying can be achieved.
4. Pelletizing Section
After drying, the wood chips enter the wood granulator. The material is sent into the ring molding machine through the feed opening and pressed into the mold hole by the pressure of the roller. Customers can choose different sizes of molds according to different needs to produce high density cylindrical pellets.
5. Cooling & Screening Section
The newly formed granules reach temperatures of 70-90℃ with high humidity, making them prone to deformation or mold growth – requiring immediate cooling. By employing a counterflow cooler that allows cold air to flow in reverse against the hot granules, rapid temperature reduction is achieved. The system also incorporates a vibrating screen to separate qualified pellets from debris and powder. Non-conforming pellets are recycled back to the granulation process for reuse, enhancing raw material utilization efficiency and reducing waste.
6. Packing Section
The cooled pellets are weighed, bagged and sewn by an automatic packaging system. Packaging specifications can be set according to customer requirements. The final product can be used in heating, industrial fuel, boiler combustion and other fields.
Supplementary note: the whole complete wood pellet plant is equipped with a feeding bag, which is convenient for different stages of feeding, and adopts efficient conveying methods such as air delivery and conveyor belt to greatly improve the efficiency of section connection.
