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

Core Forming: Fiber reorganization and densification through mechanical extrusion is a key step in converting wet wood chips into pellets. The core principle is "high-pressure extrusion + wood fiber self-bonding." Lignin (a natural adhesive that softens under pressure and frictional heat) in the wet wood chips works together with water to tightly bind the fibers, forming pellets with a fixed shape.

Core component: the forming machine—the "ring die pellet machine," which is more adaptable to wet materials and less prone to clogging.

During the extrusion process, intense friction between the sawdust and the inner wall of the die and the surface of the rollers generates frictional heat of 60-90°C. This temperature softens the lignin in the wood chips (the softening point of lignin is approximately 70-100°C). Simultaneously, the water forms "liquid bridges" that bind the dispersed fibers together, providing a foundation for subsequent shaping.

2. Characteristics of wet wood chips biomass pellet processing equipment

(1)Wide adaptability of raw materials: Reduce the cost of raw material procurement

Can directly process undried wet wood chips such as fresh leftovers from wood processing plants, wet waste wood from building demolition, wet branch slices after orchard pruning, etc.

In addition to pure wet wood chips, it can also process mixed wet materials containing wood fiber such as "wet sawdust, bark, bamboo chips" (the mixing ratio does not exceed 30%), further broadening the source of raw materials, especially suitable for users near wood processing plants and furniture factories

(2)High processing efficiency: continuous operation + low failure rate

Long continuous operation time: Due to the "integrated design" of pretreatment, molding, and cooling links, and the optimization of anti-clogging structure, the equipment can achieve 8-12 hours of continuous operation

(3)Excellent particle quality: Meet the application needs of multiple scenarios

Stable physical properties: The molded wet wood particles have high density (1.1-1.3g/cm³), high hardness (compressive strength ≥15MPa), are not easy to break during storage and transportation (breakage rate ≤3%), and have low hygroscopicity (moisture content is stable at 12%-18%), and can be stored for 6-12 =No mold growth for months;

Diverse application scenarios:As biomass fuel: The calorific value can reach 4200-4500 kcal/kg (close to medium-quality coal) when burned, and the ash content is ≤5%, suitable for industrial boilers and biomass power plants;

After crushing, it can be used as a filling matrix for organic fertilizer, realizing "turning waste into treasure".

(4)Convenient operation and maintenance: Reduce labor and operation and maintenance costs

Intelligent control: If problems such as wet material agglomeration, blockage, motor overload, etc. occur, the machine will automatically shut down and alarm, without the need for manual 24-hour on-duty;

(5)Convenient replacement of wearing parts: The wearing parts such as rollers and molds adopt a "quick-release structure" and have a long service life.

Environmental protection and policy adaptation: Meet the needs of green development

Zero wastewater discharge: No liquid wastewater is generated during the processing; dust is collected by a "bag dust collector"

Comply with biomass energy policy: The wet wood pellets produced are "renewable biomass energy"

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

In the clean energy sector, it is the core of biomass fuel production. Wet wood chip waste from lumber processing plants and furniture factories, after being processed into high-density pellets, can be used as fuel in biomass boilers, replacing coal for factory and industrial heating. It can also be used in biomass power plants and household heating stoves. Its high combustion efficiency and low carbon emissions make it suitable for the energy transition under the "dual carbon" goals. It is particularly popular in winter heating and small- and medium-sized power generation projects in northern China.

In industrial production, it supports raw material processing. The wood-based panel industry uses the wet wood chip pellets produced by the equipment as the base material for fiberboard and particleboard. The pelletized structure facilitates subsequent glue mixing and hot pressing, improving the uniformity of the board density. The papermaking industry compresses the wet wood chips using the equipment to reduce water loss and volume during transportation, thereby lowering transportation costs. Furthermore, the pelletized shape ensures uniform feeding in the pulping process, ensuring paper quality.

In agriculture and forestry, it promotes waste resource utilization. Wet wood chips from felled trees and wet fruit tree branches from orchard pruning can be processed into pellets and used as fuel for orchard frost protection and heating, as well as for greenhouse heating. The pellets can also be processed into organic mulch and used to cover farmland or forests, retaining water and suppressing weeds. This helps recycle agricultural and forestry waste and reduces incineration pollution.

In environmentally friendly treatment scenarios, it is a key tool for solid waste reduction. Wet wood chip waste from timber companies, if directly piled, is prone to rotting and stinking. Compressing it into pellets can reduce its volume by 60%-80%, making it easier to store and transport, and reducing disposal costs. The pellets can also be used as auxiliary fuel in waste incineration plants, raising the incineration temperature and reducing harmful gas emissions, meeting the needs of environmentally friendly solid waste treatment.

TONY Brand 9-10.5Ton/Hour Wet Wood Chips Pellet Manufacturing Plant can take wet wood chips, various types of wood - related biomass materials, such as wood pallets ,branches, wood logs, and wood shavings. After pretreatment and processing, wet wood chips 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. At present, it has been widely used in regions rich in wood resources.
