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

(1)Raw Material Pretreatment Stage

First, dry wood chips are crushed to an appropriate particle size (usually 3-5 mm) to ensure uniformity for subsequent compression.

(2)Mechanical Compression Molding Stage

The pretreated raw material is fed through a screw feeder between the rollers and the die of the molding machine. Under high pressure (usually 50-150 MPa), the wood chip pellets are squeezed into the die channels. During this process, the cellulose and hemicellulose components within the raw material soften under pressure and frictional heat (temperatures can reach 100-180°C), creating intermolecular bonding and forming continuous, columnar pellets.

(3)Cutting and Cooling Stage

The pellets extruded from the die are cut by a fixed blade into a desired length (usually 5-30 mm). They are then cooled to room temperature by air cooling to prevent the pellets from sticking due to residual heat. The result is a biomass pellet fuel with high hardness and density.

2. Characteristics of dried wood chips biomass pellet processing equipment

(1) Combination of forced extrusion and high-temperature shaping

The pellet machine uses a high-pressure roller-die system (the die speed is usually 150-300r/min and the extrusion pressure can reach 50-100MPa) to force the material to extrude. At the same time, the friction heat generated by the extrusion (raising the material temperature to 80-120℃) can soften the lignin in the dry wood chips. Lignin, as a natural adhesive, can melt at high temperatures and bond the fibers together, solving the problem of dry wood chips being "difficult to shape and easy to loosen", ensuring that the pellet density reaches 1.1-1.3g/cm³ (in line with industrial fuel standards).

(2) Customized die hole and roller parameters

According to the fiber length and hardness of dry wood chips, the ring die hole is designed as a conical inlet + cylindrical channel (the inlet cone angle is 15°-30°, which facilitates the entry of dry wood chip fibers and reduces clogging of the hole). The die hole diameter is mostly 6-10mm (adapting to the mainstream specifications of dry wood chip particles); the roller surface adopts spiral teeth or diamond patterns to enhance the grip of dry wood chips, avoid "slipping" caused by material drying, and improve feeding uniformity.

(3) Wear-resistant materials extend service life

Dry wood chips (especially hardwood) cause greater wear on the equipment. The ring die and roller are made of high chromium alloy (such as Cr26) or carburized quenched steel, with a surface hardness of HRC58-62, strong wear resistance, and a single service life of up to 1000-3000 hours (depending on the hardness of the wood chips), reducing the cost of frequent replacement of parts.

(4) Automation control: Equipped with a PLC control system to automatically adjust the equipment's operating status (e.g., automatically reduce feed when pellet machine pressure is too high), reducing manual intervention.

(5) Continuous production: Each device is connected through a conveyor belt and a screw conveyor, and can achieve "one-button start, continuous operation" from dry wood chip feeding to finished pellet packaging, adapting to industrial-scale processing needs.

(6) Dust control: The crushing and screening process of dry wood chips easily generates dust. The equipment is equipped with a bag dust collector (dust removal efficiency ≥ 99%), and sealing devices are installed at the feed and discharge ports to reduce dust overflow.

(7) Safety protection: Pellet machines, crushers and other high-speed running equipment are equipped with "emergency stop buttons + protective covers" to prevent safety accidents caused by equipment overload and overheating;

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

(1) Building materials industry: Wood chips can be used as raw materials for building materials and used to produce various boards and composite materials.

(2) Furniture factories: During the furniture manufacturing process, scraps and leftovers can be converted into wood chips through wet wood chip processing equipment. These pellets can be reused or used as fuel.

(3) Forestry and board mills: Wood waste generated in these places can be processed into wood chips for the production of biomass energy.

(4) Animal husbandry and feed industry: Wood chips can also be used as raw materials for feed pellets. After proper drying and processing, they can meet the needs of animal feed.

The dry wood chip processing biomass pellet project is an environmentally friendly project that relies on the conversion of agricultural and forestry waste (such as dry wood chips made from wood processing scraps, waste wood, etc.) into clean biomass energy, with both economic value and ecological benefits. The core of the project is to process dry wood chips into high-density pellet fuel (mainly used in industrial boilers, biomass power generation, home heating, etc.) through specialized equipment. Its implementation requires systematic planning of five core links: project feasibility, process design, equipment selection, cost-benefit, and risk control. 

1. Project feasibility analysis:

clarify the premise and market basis. Feasibility is the core premise for project launch and needs to be evaluated from three aspects: raw material supply, market demand, and policy environment. 

(1) Raw material supply: ensure the "source stability" of the project.

(2) Market demand: lock in target customers and pricing.

(3) Policy environment: enjoy environmental protection and industrial support.

2. Project process design:

standardize the process to ensure efficiency and quality. The process of processing dry wood chips into biomass pellets should follow the "pretreatment → molding → post-processing" principle. The core logic of the process is that process standardization is the key to ensuring stable product quality and reducing losses. 

(1) Pre-processing stage: ensuring that dry wood chips meet molding requirements.

(2) Core molding stage: the key to determining pellet quality. 

(3) Post-processing stage: ensuring storage and transportation stability. 

3. Equipment selection and plant planning:

(1) Equipment selection: configuration according to production capacity gradient. 

(2) Plant planning: meeting production process and environmental protection requirements.

Biomass pellets are a solid fuel made from processed biomass materials such as wood chips. They have the following characteristics:

1. Uniform Size:

Biomass pellets typically range from 6-10 mm in diameter and 10-50 mm in length. This uniformity makes them more stable and efficient during combustion.

2. Low Moisture Content:

The moisture content of biomass pellets is typically below 10%, which helps improve combustion efficiency and reduce smoke and pollutant generation.

3. High Energy Density:

Due to their high density, biomass pellets also have a relatively high energy density, meaning they can provide more calories per unit volume.

4. Easy Storage and Transportation:

Due to their small size and high density, biomass pellets take up less space during storage and transportation, resulting in relatively low transportation costs.

5. Environmentally Friendly:

Biomass pellets produce low smoke and carbon dioxide emissions during combustion, making them a more environmentally friendly fuel option.

6. High Combustion Efficiency:

The high energy density and low moisture content of biomass pellets ensure more complete combustion, with thermal efficiencies generally exceeding 94%. 

7. Wide Application:

Biomass pellets are suitable for environments with high environmental requirements, such as food processing plants and pharmaceutical factories. They are also suitable for industrial production lines requiring efficient heat output, such as drying equipment and steam boilers.

In summary, biomass pellets, as a fuel processed from wood chips, offer uniform size, low moisture content, high energy density, ease of storage and transportation, excellent environmental performance, high combustion efficiency, and a wide range of applications.
