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

(1)Core forming mechanism: The equipment forms the material through the rotation and extrusion of the roller and the die. After pre-treatment, the dry wood chips enter the pelletizer and form a ring-shaped material layer under the action of centrifugal force. The material is extruded through the die hole under pressure without adding adhesives. The wood fiber's own softening properties are used to complete the bonding. 

(2)Advantages of dry material processing: Some equipment supports the "dry in, dry out" mode. The moisture content of dry wood chips usually meets the processing standard of 10%-15%. The drying step can be omitted, reducing energy consumption and process complexity.

2.Characteristics of dried wood chips biomass pellet processing equipment

(1)Automatic lubrication and intelligent control: The pellet machine is equipped with an automatic lubrication system and variable frequency speed regulation function, which can adjust the speed according to the characteristics of the raw materials, avoid machine blockage problems, and reduce energy consumption. 

(2)High efficiency and energy saving and cost control Dry-in and dry-out process: When the moisture content of the raw materials is 10-15%, there is no need to dry them and they can be processed directly, which significantly reduces energy consumption costs. Low maintenance design: The equipment's vulnerable parts (such as molds and rollers) are made of high-strength materials. Combined with regular lubrication and maintenance (such as gear oil replacement and metal impurity cleaning), they can extend their service life and reduce downtime.

(3)Environmental protection and resource recycling Zero additives and pollution-free: The processing process does not require adhesives and relies on the softening and bonding of lignin itself. When the finished product is burned, there is no harmful emission such as sulfur dioxide, which meets the requirements of energy conservation and emission reduction. Waste resource utilization: Agricultural and forestry waste such as dry wood chips and waste wood can be converted into high-value pellet fuel, realizing "waste to treasure" and contributing to the circular economy.

(4)Application scenarios and market adaptability The equipment is widely used in industrial boilers, biomass power plants, civil heating and other fields. With the advancement of environmental protection policies, equipment is extending from traditional energy replacement to diversified fields such as feed and fertilizer, and market demand continues to grow.

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

(1)Energy production Biomass power generation: Processed pellet fuel can be directly used in biomass power plants as a boiler fuel, replacing traditional fossil energy and reducing carbon emissions. Heating and heating: Suitable for industrial boilers, commercial fireplaces and household heating equipment, providing clean and renewable heat. 

(2)Industrial and manufacturing fields Board production: Crushed wood chips can be used as raw materials for particleboard, fiberboard, plywood and other boards, improving the utilization rate of wood resources. Paper and pulp: Crushed wood chips can be used for pulp production after processing, meeting the papermaking industry's demand for fiber raw materials.

(3)Environmental protection and resource recycling fields Agricultural and forestry waste treatment: Convert agricultural and forestry waste such as logs, branches, and straw into pellet fuel, reducing solid waste accumulation and promoting a circular economy. Fossil fuel replacement: Replace coal and oil in scenarios such as biomassdiesel production and power plant fuel, reducing environmental pollution.

Risk Control and Operation Recommendations for Dry Wood Chip Processing Biomass Pellets Project

1.Core Risks and Countermeasures

(1)Raw Material Risk: Raw material shortage and price increase

Sign long-term agreements with 3-5 suppliers to lock in price and supply;

Expand raw material sources (e.g., cooperate with forestry departments to recycle logging residues);

Reserve 15-30 days of raw material inventory

(2)Quality Risk: Pellet density does not meet standards and yield is low

Establish a raw material testing system (measure moisture and impurities for each batch);

Regularly maintain the pellet machine (clean the ring die weekly and check the rollers monthly);

Train operators and familiarize them with parameter adjustments (e.g., pressure, temperature)

(3)Market Risk: Pellet price drop and demand reduction

Binding long-term customers (e.g., signing a 1-3 year supply agreement with a power plant);

Expanding multi-scenario customers (industrial + civil + export);

Improving product quality (entering the high-end market)

(4)Environmental Risk: Exceeding dust emission standards and failing environmental inspections

Maintain the dust removal system regularly (replace filter bags monthly);

Install online monitoring equipment (real-time monitoring of dust concentration);

Reserve environmental emergency funds (to cope with unexpected inspections)

2.Operational optimization suggestions

(1)Optimize raw material pretreatment:

For dry wood chips containing impurities (such as scrap wood with nails), add a "magnetic separation + manual sorting" step to avoid damage to the equipment;

(2)Equipment maintenance plan:

Establish a "daily inspection (check screws, lubrication), weekly inspection (clean mold holes, filter bags), monthly inspection (replace wearing parts)" system to extend the life of the equipment;

(3)Cost control details:

Reuse of scrap materials (can reduce raw material loss by 5%-10%), staggered electricity use (use off-peak electricity hours for production to reduce electricity costs), and recycling packaging materials (woven bags can be reused 2-3 times).

1.Outstanding environmental value: renewable, low-carbon, and contribute to "dual carbon" 

(1)100% renewable, recycling resources

The raw materials mainly come from wood processing waste (such as wood chips, sawdust, scraps), forestry residues (such as branches, bark), without consuming natural timber, realizing the "waste-to-treasure" of agricultural and forestry waste, avoiding the methane (strong greenhouse gas) generated by the accumulation and decay of waste or the pollution caused by incineration, and promoting the recycling of resources. 

(2)"Carbon neutral" emissions, in line with low-carbon goals 

The carbon dioxide released by the combustion of wood pellets is basically balanced with the amount of carbon dioxide absorbed during the growth of trees. From the perspective of the life cycle, it is a "carbon neutral" energy source and can replace fossil energy such as coal and oil, helping to reduce carbon emissions in industries such as industry and heating, and is in line with the global "dual carbon" strategy and the environmental protection policy orientation of various countries. 

2.Good economic efficiency: controllable costs and policy support

(1)Low raw material costs and stable supply

The raw materials are wood processing waste or forestry residues. The procurement cost is much lower than coal and natural gas. The raw materials are widely sourced (furniture factories, wood processing plants, forest farms, etc.). The supply chain is stable and there is no need to worry about raw material shortages.

(2)Obvious production and use cost advantages

Although the pelletizing process requires equipment and energy consumption, the high calorific value and high transportation efficiency of the pellet products can offset some of the costs. For example, under the same heat demand, the cost of using wood pellets is 20%-30% lower than natural gas and 40%-50% lower than electric heating, which is attractive to both businesses and households.
