1. The working principle of wet sawdust biomass pellet processing equipment

Core Forming: Fiber reorganization and densification under mechanical extrusion is a key step in converting sawdust into pellets. The core principle is "high-pressure extrusion + wood fiber self-bonding." Lignin in the sawdust (a natural adhesive that softens under pressure and frictional heat) works together with moisture to tightly bind the fibers, forming pellets with a fixed shape.

Core component: The forming machine—the "ring die pellet machine"—is more adaptable to wet materials and less prone to clogging.

During the extrusion process, intense friction between the sawdust and the inner wall of the die and the surface of the rollers generates frictional heat of 60-90°C. This temperature softens the lignin in the sawdust (the softening point of lignin is approximately 70-100°C). Simultaneously, the moisture forms "liquid bridges" that bind the dispersed fibers together, providing a foundation for subsequent shaping.

2. Characteristics of wet sawdust biomass pellet processing equipment

(1) Strong adaptability to raw materials, compatible with a variety of biomass

Wide processing capacity: Processable raw materials include wet sawdust, wood shavings, etc.

Clear requirements for raw material pretreatment: The moisture content of the raw materials must be controlled at 10%-15% (too high a moisture content will easily cause adhesion and mold clogging, while too low a moisture content will result in insufficient pellet strength), and the particle size is usually required to be 1-3mm.

(2) Modularization of core equipment and continuous production process

 Modular combination: A typical production line consists of "drying equipment (humidification) → granulation equipment (forming) → cooling equipment (cooling) → screening equipment (screening) → packaging equipment". Each module can be flexibly increased or decreased according to production capacity requirements (for example, for small production lines, some auxiliary equipment can be omitted).

 Continuous operation: Through the connection of various links such as conveyor belts and screw feeders, automated continuous production from raw material input to finished product output is achieved.

3. Application scenarios of wet sawdust biomass pellet processing equipment

Processing equipment provides fuel for factory boilers and kilns (replacing coal and oil), such as steam boilers in textile and food processing plants, and heating kilns in the ceramics and building materials industries. Stable pellet production ensures energy supply.

Power Generation:

Biomass power plants require large quantities of standardized pellets as fuel. Large-scale processing equipment can meet the power plant's stringent requirements for pellet calorific value and density, ensuring efficient combustion and stable power generation.

Residential Heating:

For pellets used in home fireplaces and space heaters, processing equipment must control pellet size and hardness to accommodate residential combustion equipment. The equipment's refined production capabilities directly impact the user experience of these pellets.

Environmental Protection and Waste Management:

In waste and sewage treatment plants, processing equipment converts organic waste (such as sludge and food waste) into fuel pellets for resource recovery. Corrosion-resistant and clogging-resistant designs are crucial.

Project Advantages: Market competitiveness and environmental value

(1) Excellent product characteristics and strong market competitiveness

Biomass pellets have many excellent characteristics. Their calorific value is high, generally 4200-4800 kcal/kg, close to medium-quality coal, and can provide sufficient heat; they have low ash content, and very little ash remains after combustion, reducing cleaning costs and environmental pollution; they have low emissions, extremely low sulfur content (usually <0.05%), and low nitrogen content. The pollutants such as SO₂ and NOₓ produced during combustion are much lower than those produced by burning coal, meeting strict environmental protection standards and are highly favored by customers with high environmental protection requirements. In addition, biomass pellets have a regular shape, mostly cylindrical pellets with a diameter of 6-12mm and a length of 20-50mm. The density can reach 0.8-1.2g/cm³, high hardness, not easy to break, and easy to store and transport, further enhancing the market competitiveness of the product. 

(2) Significant environmental benefits and high social value

The development of the biomass pellet industry is to "turn waste into treasure" for agricultural and forestry waste, realize the recycling of resources, and reduce the pollution of waste to the environment. At the same time, during the combustion process of biomass pellets, the carbon dioxide emissions are basically balanced with the carbon dioxide absorbed during plant growth, achieving "carbon neutrality", helping to alleviate the greenhouse effect and improve air quality. This not only complies with the national environmental protection policy, but also establishes a good corporate image for entrepreneurs, bringing high social reputation and potential business opportunities.

The environmental advantages of sawdust biomass pellets are their core competitive advantage, primarily reflected in their "low carbon footprint throughout their lifecycle" and "low pollution during combustion":

1. Low carbon and renewable, aligning with the "double carbon" goal: Sawdust, derived from wood processing waste, is a "biomass resource." The CO₂ absorbed during its growth is essentially balanced by the CO₂ released during combustion, achieving "carbon neutrality." Compared to coal (a fossil energy source whose combustion releases ancient carbon), it can reduce net carbon emissions by over 90%, making it an ideal alternative fuel for achieving both peak and neutral carbon emissions.

2. Low combustion pollutants, reducing the environmental burden: Combustion is almost sulfur-free (sulfur content ≤ 0.05%) and nitrogen-free (nitrogen content ≤ 0.5%), and does not produce large amounts of SO₂ and NOₓ (the main pollutants from traditional coal combustion), which can significantly reduce the risk of acid rain and haze. The ash content is extremely low (only 2%-5%, far lower than the 10%-20% of coal). The small amount of ash remaining after combustion can be used as organic fertilizer or auxiliary building materials, eliminating the problem of "secondary pollution of solid waste."

3. Non-spontaneous combustion and safe storage: Pellets have a low moisture content but a dense structure, resulting in a small contact area with air. They won't spontaneously combust at room temperature (they require a high-temperature open flame to ignite). In contrast, pulverized coal and loose sawdust, due to their large surface area, are susceptible to spontaneous combustion due to oxidation and heat generation. Pellets also contain no volatile flammable gases, preventing explosions from leaks like liquefied petroleum gas.

4.No toxic gases are produced during combustion, ensuring safe use: Pellets do not produce toxic gases such as carbon monoxide (CO) and formaldehyde (assuming complete combustion and suitable combustion equipment). Incomplete combustion of coal can easily produce CO, while firewood can easily produce smoke and tar. Pellets are more health-friendly and are particularly suitable for applications involving direct human or product contact, such as residential heating and food processing (such as drying tea leaves and medicinal herbs).
