Project Layout For Customer:

1. The working principle of dried wood log biomass pellet processing equipment

The core principle of dry wood biomass pellet processing equipment is to use mechanical extrusion to densify dry wood chips. Frictional heat generated by extrusion activates the natural adhesive properties of lignin, achieving glue-free molding. The entire process relies on low moisture content in the raw material to ensure molding efficiency and pellet strength, appropriate particle size to ensure uniform force distribution, and precise coordination between the ring die and rollers to provide sufficient extrusion pressure and temperature. Ultimately, the loose wood waste is transformed into efficient and clean biomass pellet fuel.

2. Characteristics of dried wood log biomass pellet processing equipment

 (1)Environmental protection and energy saving, in line with the concept of green production

 Low pollution emissions: No wastewater is generated during the processing process. Only a small amount of waste gas may be generated during the drying process (if necessary), but it can be effectively purified by the supporting dust removal equipment (such as cyclone separators, bag dust collectors), which meets environmental protection standards.

 Relatively low energy consumption: Since the raw materials are already dried, the high-energy-consuming deep drying process is eliminated; and the pelletizing process uses extrusion friction to generate heat, without the need for additional heating (or only auxiliary heating), and the overall energy consumption is lower than that of wet material processing equipment.

Outstanding environmental attributes of the product: The biomass pellet fuel produced has low carbon emissions when burned (approximately "carbon neutral"), and the sulfur and nitrogen content is much lower than that of coal. It can replace fossil fuels, reduce environmental pollution, and contribute to the "dual carbon" goal.

(2) High degree of automation and easy operation and maintenance

Automatic control system: The complete set of equipment is usually equipped with a PLC control system, which can realize the linkage control of raw material transportation, feeding, pelletizing, cooling, screening and other links, and automatically monitor parameters such as raw material moisture content, pellet temperature, equipment load, etc., reducing manual intervention. Easy-to-maintain design: Core components (such as ring dies, rollers, and blades) are made of high-strength, wear-resistant materials (such as alloy steel) with a long service life. The modular structure makes it easy to disassemble, replace, and repair, reducing downtime and maintenance costs.

Complete safety protection: The equipment is equipped with safety devices such as overload protection, temperature alarm, and emergency stop button, which can effectively avoid damage caused by raw material impurities (such as metal blocks) or equipment failure, ensuring production safety.

3. Application scenarios of dried wood log biomass pellet processing equipment

Dry wood processing biomass pellet equipment (hereinafter referred to as "dry wood pellet equipment") is mainly used to process dry wood waste (such as sawdust, shavings, wood scraps, branches, etc., with a moisture content of 10%-15%) into high-density biomass pellet fuel. Its application scenarios revolve around "wood waste resource utilization" and "clean energy substitution".

(1) Utilization of forestry waste: felled branches, trunk segments, dead wood, etc., after crushing (dry material state), can be processed into pellets by the equipment to solve the problem of scattered and difficult transportation of forest waste (pellet density reaches 1.1-1.3g/cm³, and transportation efficiency is increased by 5-8 times).

(2) Treatment of fruit tree pruning waste: dry branches (such as apple wood and pear wood) produced by orchard pruning are crushed and processed into fuel through pellet equipment. Due to their high calorific value (about 4200-4500kcal/kg), they can be supplied as high-quality biomass fuel to farmers or small heating units.

TONY Brand 3-4 Ton/Hour Dried Wood Log Pellet Manufacturing Plant can take dried wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with dried wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel. This fuel is an ideal substitute for coal and oil and plays a role in energy conservation and emission reduction. At present, it has been widely used in regions rich in wood resources.

Processing dry wood into biomass pellets is a truly entrepreneurial venture that combines policy dividends, market potential, and environmental value, offering numerous feasibility and advantages.

1. Low technical barriers to entry

The production process is simple: dry wood crushing → extrusion pelletizing → cooling → packaging. The technology is mature and easy to master.

2. Diverse and robust market channels

Civilian use: The "coal-to-biomass" shift in rural areas of northern China has driven heating demand, with farms and greenhouses using biomass for insulation. Annual demand is growing with agricultural scale-up.

Industrial use: Biomass power plants, food factories, building materials factories, and other industries are using biomass pellets to replace coal/natural gas, resulting in high and stable demand.

3. Significant profit margins

After deducting costs such as site rental and labor, net profit still remains substantial.

4. Wide range of dry wood raw materials:

Wood processing plant scraps and sawdust (a long-term, stable supply, often free or at a low price);Tree branches and trunks from forestry pruning (which can be crushed and used, with forestry departments in some areas assisting in this connection);

Crop straw (if local wood resources are limited, this can be used in combination to further reduce raw material costs). The renewable nature of the raw materials ensures the long-term operation of the project without worrying about resource depletion.

Physical Properties of Wood Pellets

1. Regular Shape and High Density

The pellets are cylindrical (6-10mm in diameter, 20-30mm in length), compact, and have a density of 1.1-1.3 tons/cubic meter (4-5 times that of dry wood), significantly reducing storage space (for the same volume, the storage capacity is over 3 times that of loose wood chips).

2. Low Moisture Content, Resistant to Deterioration

Dry wood has a low moisture content (typically ≤15%, controlled at 8%-12% during processing). Once pelletized, they absorb little moisture and can be stored for 6-12 months in a ventilated, dry environment without deterioration, avoiding the mold and rot associated with wet wood.

3. Good flowability, facilitating automated handling

The pellets have a smooth, lumpy surface and can be transported automatically through pipes, conveyors, and other equipment. They are compatible with automated feed systems for boilers and fireplaces, reducing manual labor.
