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

The core principle of wood pellet processing equipment, such as wood pellet mills, is to convert biomass feedstock into high-density pellet fuel through mechanical compression. The basic process involves three steps: pelletizing, cooling, and packaging. For example, in a ring die pellet mill, a motor connected to a reducer via a coupling drives the ring die. The feedstock enters the compression zone under gravity, where rollers squeeze the material into the ring die holes. After the pellets are formed in the die, they are cut into fixed lengths by a cutter.

2. Characteristics of dried sawdust biomass pellet processing equipment

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

Wide processing capacity: Processable raw materials include dry 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 can 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 "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 dried sawdust biomass pellet processing equipment

(1)Industrial boilers/kilns: Used for heating processes in industries such as building materials, chemicals, and food processing, including tile firing, feed drying, and factory heating.  This aligns with environmental policies requiring reduced coal consumption and carbon emissions.

(2)Residential heating/cooking: The processed pellet fuel can be used in residential boilers and biomass stoves, and is widely used in rural areas in northern China for "coal-to-clean energy" projects.  It burns cleanly with no black smoke and low ash content (typically <5%).

(3)Power generation: Some large biomass power plants purchase pellet fuel processed by this equipment as raw material for their biomass power generation units, thus promoting energy recycling.

TONY Brand 32-40 Ton/Hour Dried Sawdust Pellet Manufacturing Plant can take dried sawdust,wood chips, various types of wood - related biomass materials, such as wood pallets ,branches, wood logs, and wood shavings. After pretreatment and processing, dried sawdust 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.

Market Demand: Policy-Driven and Strong End-User Needs

Policy Support: Under the national "dual carbon" target, many regions have implemented policies to restrict coal use (e.g., "coal-to-electricity/coal-to-biomass" projects in northern China), and biomass pellet fuel benefits from tax rebates and environmental subsidies;

Demand Scenarios:Industrial Sector: Boiler heating in building materials plants, food processing plants, and feed mills, with high demand for pellet fuel (up to several thousand tons per plant annually);

Residential Sector: Heating in rural areas of northern China and cooking in suburban households, with a stable retail market;

Energy Sector: Raw material procurement for biomass power plants, with large and stable long-term orders.

Environmental Advantages: Low Pollution, Carbon Neutrality, and Policy Compliance

Extremely Low Emissions:  No black smoke during combustion; sulfur dioxide emissions are only 0.005-0.01 g/m³ (far lower than 0.1-0.3 g/m³ for coal), nitrogen oxide emissions are <50 mg/m³, and particulate matter emissions are <10 mg/m³.  These all meet the "Special Emission Limits" in the National Standard for Boiler Air Pollutant Emission (GB 13271-2014), eliminating the need for complex flue gas treatment equipment.

Zero Carbon Emissions through Carbon Cycle: Sawdust originates from wood that absorbed CO2 during tree growth. The CO2 released during combustion is reabsorbed by newly planted trees, creating a carbon cycle. Compared to coal (fossil carbon, which releases new carbon emissions upon combustion), this essentially achieves carbon neutrality, aligning with the national "dual carbon" target and making it a clean fuel promoted by government policy.

Recyclable Solid Waste: The ash produced (less than 5% of the total) is rich in potassium, calcium, and other elements, and can be used directly as fertilizer or soil conditioner, avoiding secondary solid waste pollution.  Coal ash, on the other hand, requires special treatment and can cause heavy metal pollution of the soil.
