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

(1)Raw Material Pretreatment Stage

First, dry wood chips are crushed to an appropriate particle size (usually 3-5 mm) to ensure uniformity for subsequent compression.

(2)Mechanical Compression Molding Stage

The pretreated raw material is fed through a screw feeder between the rollers and the die of the molding machine. Under high pressure (usually 50-150 MPa), the wood chip pellets are squeezed into the die channels. During this process, the cellulose and hemicellulose components within the raw material soften under pressure and frictional heat (temperatures can reach 100-180°C), creating intermolecular bonding and forming continuous, columnar pellets.

(3)Cutting and Cooling Stage

The pellets extruded from the die are cut by a fixed blade into a desired length (usually 5-30 mm). They are then cooled to room temperature by air cooling to prevent the pellets from sticking due to residual heat. The result is a biomass pellet fuel with high hardness and density.

2.Characteristics of dried wood chips biomass pellet processing equipment

(1)Strong adaptability:

The biomass pellet machine can adapt to various raw materials, including dry wood chips.

(2)High-efficiency pelletizing:

The centrifugal force is used to make the material continuously move in a circular motion and adhere to the inner wall of the die, forming a uniform annular material layer. The roller continuously rotates and squeezes the material, forcing it into the ring die hole for molding.

(3)Environmental protection and energy saving:

The pellet fuel produced by the biomass pellet machine has the advantages of high density, high calorific value, good combustion, low cost, convenient use, clean and hygienic, easy to store and transport, etc. It can replace firewood, coal, natural gas, liquefied gas, etc. and is widely used in domestic stoves, heating stoves, hot water boilers, drying furnaces, industrial boilers, etc.

(4)High degree of automation:

The TONY biomass pellet machine has a fully automatic lubrication function and can work 24 hours a day, reducing manual intervention and improving production efficiency.

(5)Low maintenance cost:

Some biomass pellet machine equipment has low maintenance cost, no need to add grease, the wearing parts are practical and durable, and the roller bearings are international brands and are not easy to damage.

(6)Compact process:

The biomass pellet machine has compact process, small footprint, good dust removal effect, low noise and good production environment.

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

(1)Biomass energy field

As a clean fuel: The processed wood pellets have high calorific value and high combustion efficiency, and their sulfur, ash and nitrogen content are much lower than fossil fuels such as coal and oil. They can be directly used for fireplaces and boiler heating, or as fuel for biomass power plants, achieving energy substitution and emission reduction goals.

Energy conversion advantages: Compared with traditional fuels, wood pellets are smokeless and odorless when burned, with low pollutant emissions, which meets the needs of modern green energy, especially in Europe and America where the demand for biomass energy is relatively high.

(2)Animal feed field

Feed pellet production: Wood pellets processed by wood pellet machines can be used as high-quality feed for poultry and livestock breeding, improving feed utilization and animal production efficiency. Some equipment is specially designed for feed pellets to meet the process requirements of feed processing.

(3)Environmental protection and resource recycling field

Wood waste processing: The equipment uses wood chips, sawdust, branches and other wood processing waste as raw materials, converting waste that might have been discarded into high-value pellet products, realizing resource recycling and 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).

Processed biomass pellets have the following characteristics:

1.High density and high energy:

Volume density can reach 1.1-1.3 tons/cubic meter, with a calorific value of approximately 4,000-4,500 kcal/kg, making them easy to store and transport.

2.Environmentally friendly and renewable:

Combustion produces near-zero CO₂ emissions, and the sulfur and nitrogen content are low, making them a viable alternative to coal or natural gas for industrial boilers, hot air furnaces, and other equipment.

3.Fuel cost advantage:

Compared to natural gas, fuel costs are 30%-50% lower, and the raw material source is broad (such as wood processing waste and crop straw).

This technology not only enables the resourceful utilization of agricultural and forestry waste but also provides a low-carbon solution for industrial heating, making it a key development direction in the renewable energy sector.
