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

The core logic of processing dry wood chips into biomass pellets is to pre-treat the raw materials to meet the "extrudability" requirement, then use the "pressure generated by extrusion + frictional heat" to soften and bond the lignin, and finally cool and shape it into high-density pellets. The entire process does not require the addition of chemical adhesives (relying on the natural viscosity of lignin), which is both environmentally friendly and ensures the combustion performance and stability of the pellets. It is currently one of the mainstream technologies for biomass energy resource utilization.

2. Characteristics of dried wood chips biomass pellet processing equipment

(1) Combination of forced extrusion and high-temperature shaping

The pellet machine uses a high-pressure roller-die system (the die speed is usually 150-300r/min and the extrusion pressure can reach 50-100MPa) to force the material to extrude. At the same time, the friction heat generated by the extrusion (raising the material temperature to 80-120℃) can soften the lignin in the dry wood chips. Lignin, as a natural adhesive, can melt at high temperatures and bond the fibers together, solving the problem of dry wood chips being "difficult to shape and easy to loosen", ensuring that the pellet density reaches 1.1-1.3g/cm³ (in line with industrial fuel standards).

(2) Customized die hole and roller parameters

According to the fiber length and hardness of dry wood chips, the ring die hole is designed as a conical inlet + cylindrical channel (the inlet cone angle is 15°-30°, which facilitates the entry of dry wood chip fibers and reduces clogging of the hole). The die hole diameter is mostly 6-10mm (adapting to the mainstream specifications of dry wood chip particles); the roller surface adopts spiral teeth or diamond patterns to enhance the grip of dry wood chips, avoid "slipping" caused by material drying, and improve feeding uniformity.

(3) Wear-resistant materials extend service life

Dry wood chips (especially hardwood) cause greater wear on the equipment. The ring die and roller are made of high chromium alloy (such as Cr26) or carburized quenched steel, with a surface hardness of HRC58-62, strong wear resistance, and a single service life of up to 1000-3000 hours (depending on the hardness of the wood chips), reducing the cost of frequent replacement of parts.

(4) Automation control:

Equipped with a PLC control system to automatically adjust the equipment's operating status (e.g., automatically reduce feed when pellet machine pressure is too high), reducing manual intervention.

(5) Continuous production:

Each device is connected through a conveyor belt and a screw conveyor, and can achieve "one-button start, continuous operation" from dry wood chip feeding to finished pellet packaging, adapting to industrial-scale processing needs.

(6) Dust control:

The crushing and screening process of dry wood chips easily generates dust. The equipment is equipped with a bag dust collector (dust removal efficiency ≥ 99%), and sealing devices are installed at the feed and discharge ports to reduce dust overflow.

(7) Safety protection:

Pellet machines, crushers and other high-speed running equipment are equipped with "emergency stop buttons + protective covers" to prevent safety accidents caused by equipment overload and overheating;

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

(1) Biomass power generation/heating enterprises

Typical scenarios: Biomass power plants and industrial boilers (such as heating boilers in textile factories and food factories) require a large amount of stable pellet fuel

(2) Small and medium-sized heating/drying users

Typical scenarios: Rural heating stations, agricultural product drying plants (such as grain, fruit and vegetable drying), greenhouse heating; processed pellets are directly stored in the silo of the heating station and can be taken out as needed.

(3) "Self-circulating" processing in orchards/tea gardens

Typical scenarios: After being processed into pellets, they can be used as fuel for the orchard's "biomass hot air furnace" (for fruit tree frost protection and fruit drying), or crushed and buried in the soil to improve soil quality, realizing "self-circulating waste in the park";

(4) Environmental protection and solid waste treatment fields

Typical scenarios: Urban solid waste treatment plants (sorted wood waste), garden waste treatment stations ( branches,  shrub slices)

The market demand for wood chip pellets is diverse.Core markets include:

1. Biomass Energy Market: Replacing fossil fuels, driven by policy.

Biomass power plants and industrial boilers (in the textile, food, and chemical industries) require large quantities of pellet fuel. Wood pellets have a calorific value of 4200-4500 kcal/kg and are 50% cheaper than natural gas and 30% cheaper than coal (especially in coal-free zones), making them the cost-effective choice for power plants and boiler users.

Wood pellets can be used directly in pellet stoves for rural heating, greenhouses, and agricultural product drying (grain, fruits, and vegetables), requiring no complex modifications and enjoying high user acceptance. 

2. Agricultural Recycling Market: Facilitating the "farming-livestock cycle."

After crushing, wood pellets can be used as a roughage carrier for cattle and sheep (mixed with silage to improve feed palatability) or as a base for organic fertilizer (absorbing moisture from livestock and poultry manure, adjusting the carbon-nitrogen ratio, and complying with the "manure resource utilization" policy).

Agricultural parks, such as orchards and tea plantations, can process pruned wet branches into pellets for use in park heating and fruit drying, achieving "in-park waste recycling."

3. Solid Waste Management Market: Replacing "landfill/incineration," driven by environmental protection needs.

The wet wood portion of urban renovation waste and garden waste is traditionally disposed of by landfill (occupying land) or incineration (generating dioxins). However, wet wood pellet projects can convert this waste into clean energy.

Biomass pellets (i.e., wood pellets) processed from wood chips are a clean, renewable biomass energy product. Their energy advantages are primarily reflected in their high calorific value, easy combustion, and strong stability.

1. High density + high calorific value, high energy efficiency

After compression and pelletization, wood chips are significantly reduced in volume (density can reach 1.1-1.3 tons/m³, 4-5 times that of loose wood chips), while their energy density per unit volume is significantly increased (lower calorific value is approximately 4200-4800 kcal/kg, close to that of medium-quality coal). Heat release is concentrated during combustion, resulting in a thermal efficiency 30%-50% higher than directly burning loose wood chips. This makes them suitable for applications with stable heat demand (such as industrial boilers and biomass power generation). 

2. Complete combustion and low pollutant emissions.

Wood pellets have a uniform structure and controllable moisture content (dried to 10%-15% during processing). They are not prone to charring during combustion and contain no harmful elements such as sulfur and phosphorus. Exhaust emissions of sulfur dioxide and nitrogen oxides after combustion are extremely low (far lower than those from coal combustion). Dust emissions can also be reduced to meet environmental standards with simple treatment.

3. Convenient storage and transportation, strong stability.

The pellets have a regular shape (mostly cylindrical, 6-10mm in diameter and 10-30mm in length) and good fluidity. They can be transported in bags or bulk, requiring only one-fifth the storage space of loose wood chips. Furthermore, the pellets have a low moisture content and are resistant to mold and mildew. They can be stored for 6-12 months, eliminating the need to worry about raw material deterioration.
