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.

(1)Low pollution emissions: The sulfur and phosphorus content during combustion is extremely low, and the concentration of SO₂ and NOx in the flue gas is much lower than that of coal. It will not produce acid rain, and CO₂ emissions are zero (because plants absorb CO₂ during growth)

(2)Ash utilization: Ashes after combustion are rich in organic potassium and can be recycled as high-efficiency organic fertilizer       

2.Economical

(1)Wide range of raw materials: waste such as wood processing waste and crop straw can be used, and the production cost is lower than traditional fossil fuels.

(2)Substitution benefits: Replacing coal can save about 20% to 30% of fuel costs 

 3.Wide range of application scenarios

(1)Industrial applications: Widely used in boiler heating, power generation and industrial production, such as textile factories, food factories, etc. 

(2)Civil heating and living energy: Wood pellets have high combustion efficiency, are easy to store and use, and are safe and hygienic.

(3)Biomass industrial boiler: As the main fuel for industrial boilers, it replaces coal, heavy oil and natural gas to solve environmental pollution problems.
