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

The pelletizing equipment is the core of the entire production line. Its principle is to use "mechanical extrusion + lignin softening" to compress loose fine wood chips into high-density pellets with a circular cross-section (diameter 6-12mm, commonly 8mm) and a length of 3-10mm. The key lies in the ring die pelletizer (mainstream equipment in the industry)

(1) Feeding and pre-pressing: The fine wood chips that meet the standards are evenly fed into the pelletizing chamber by the feeding agitator. The feed plate in the chamber distributes the wood chips to the gap between the ring die and the pressure roller (the ring die is a circular steel die with uniform small holes, and the pressure roller is 2-3 rotatable cylindrical rollers. The ring die is fixed and the pressure roller is driven by the ring die to rotate);

(2) High-pressure extrusion: The pressure roller rotates at high speed under the friction of the ring die (ring die speed 15-30r/min), forcibly pressing the wood chips into the small holes of the ring die - at this time, the extrusion pressure can reach 50-150MPa. The loose wood chips are compressed under high pressure and their volume is reduced to their original size. 1/5-1/3, the density is increased to 1.1-1.3g/cm³ (much higher than the raw material 0.2-0.5g/cm³);

(3) Lignin bonding: During the extrusion process, the friction heat generated by high pressure (temperature can reach 80-120℃) will soften and melt the lignin (natural adhesive) in the wood chips, wrapping the cellulose and hemicellulose particles; when the material is extruded from the ring die holes, the temperature drops and the lignin re-solidifies, firmly bonding the wood chips together to form cylindrical particles with stable structure;

Pelletizing: The cutter (adjustable position) on the outside of the ring die cuts the extruded continuous particles into set lengths (3-10mm), completing the pelletizing process

2. Characteristics of dried wood pallets biomass pellet processing equipment

(1) Flexibility in raw material processing: The wood pellet machine is suitable for processing various wooden pallets, density boards, artificial boards and other different products. 

(2) Low energy consumption and environmental protection:The equipment adopts a spiral feeding device, with an energy utilization rate of 85%; The fully enclosed structure reduces dust and noise pollution.

(3) Durability and easy maintenance:The key components are made of special steel and specially treated, which ensures a long service life of the equipment. The whole machine has a compact structure and a small footprint, and can be put into production after installation and commissioning. 

(4) Easy maintenance and cost control:The pellet machine adopts an automatic refueling system to save maintenance costs; the equipment troubleshooting is simple, and no professional personnel are required for daily maintenance. 

(5) Resource recycling:The waste of wooden pallets is converted into recycled products such as pellet fuel to achieve efficient recycling of wood resources.

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

(1) Small and medium-sized pellet plants (regional):After introducing dry pallet pellet processing equipment, they can supplement raw materials by recycling discarded pallets from surrounding logistics companies, broaden raw material channels, reduce dependence on a single wood chip supplier, and ensure full-load operation of the production line. 

(2) Large-scale pellet plants (industrial grade):For example, large-scale pellet plants serving power plants and chemical plants require a large amount of wood raw materials to support production. Pellets processed from discarded dry pallets (high density and stable wood fiber) have "higher combustion value and lower ash content" (better than ordinary wood chip pellets) and can be used as raw materials for "high-end pellets" (such as pellets for industrial boilers), increasing the selling price of finished products (10%-20% higher than ordinary pellets). 

(3) Professional wood solid waste treatment companies:For example, environmental protection companies that process discarded furniture and construction wood waste. Discarded dry pallets are compatible with this type of wood waste (both are solid wood/artificial wood). The equipment can be "integrated for processing" without the need for separate classification, improving processing efficiency; the processed pellet fuel can be used as the company's "core product for export", expanding from "single processing service" to a complex business of "processing + product sales", thereby improving profitability.

(4) Regional new energy entrepreneurs:By recycling waste dry pallets from surrounding enterprises and processing pellets, the raw material acquisition cost is low (even free), and the finished products can be sold to local factories and heating companies (within a sales radius of 50 kilometers, and transportation costs are controllable). The investment is small and the return is fast, which is suitable for small and medium-sized entrepreneurs.

(5) Environmental protection investment companies:This type of enterprise focuses on "green and low-carbon projects". Dry pallet pellet processing projects combine "solid waste treatment (environmental protection attributes)" and "biomass energy (new energy attributes)". After investment, stable returns are obtained, while improving the company's ESG rating.

TONY Brand 15-18Ton/Hour Dried Wood Pallets Pellet Manufacturing Plant can take dried wood pallets, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings.

The dry pallet processing of biomass pellet fuel projects has promising development prospects. The following is an analysis from market, technical, economic, and environmental perspectives:

1.Market Demand: 

With increasing environmental awareness, the market demand for biomass pellet fuel as a clean fuel continues to grow. The widespread use of biomass pellet fuel as a replacement for coal-fired heating has further expanded market demand.

2.Technical Feasibility: 

The technology for dry pallet processing of biomass pellet fuel is relatively mature. Key production equipment, such as crushers, pulverizers, and pelletizers, is readily available. Environmentally friendly treatment technology is also well-established. A "cyclone dust collector + bag filter" system is used to treat dry flue gas, achieving a particle removal efficiency of up to 99%.

3.Economic Benefits:

While the specific costs and profits of dry pallet processing projects vary depending on factors such as region, raw material prices, and equipment selection, they generally offer good economic benefits when raw material supply is stable and market prices are reasonable.

4.Environmental Benefits:

Biomass pellet fuel processed from dry pallets produces less harmful gases such as sulfur oxides and nitrogen oxides, has a low ash content, and has a minimal environmental impact, meeting environmental protection requirements. This helps reduce air pollution and promotes sustainable development.

Dry pallet pellets are positioned as "mid-to-high-end wood pellets" and are suitable for different applications:

1. Residential applications (home fireplaces, heating stoves):

They offer significant quality advantages—low ash content (requires long cleaning cycles, typically every 1-2 weeks), smokeless and odorless (combustion is complete, with pollutant emissions far lower than coal and bulk biomass), high density (requires minimal storage space, with 1 ton of pellets equivalent to approximately 0.8-1 cubic meters), and a superior user experience compared to ordinary straw pellets.

2. Industrial applications (factory boilers, biomass power plants):

They offer quality that meets the requirements of continuous operation—stable calorific value (fluctuation ≤5%), high pellet yield (reducing feed system clogging), and low ash content (reducing coking on boiler heating surfaces and extending equipment life). They can partially or completely replace coal (calorific value: 1.8-2 tons of pellets equals 1 ton of coal) and comply with environmental protection policies (carbon emissions from biomass fuel combustion are near "carbon neutral"). 

3. Special Applications (Greenhouse Heating, Food Processing and Drying):

Pellets produced from pure solid wood pallets meet low-pollution requirements and are suitable for applications with high air quality requirements.
