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

The core of the wet wood chip pellet processing equipment is to convert wet wood chips with a moisture content of 15%-35% into high-density pellets. Its principle revolves around two major systems: pretreatment and forming, addressing the problems of wet material clumping and difficulty in forming.

The pretreatment system paves the way for subsequent forming. The comminution module first processes the wet wood chips, which are then passed through a dedicated pulverizer. High-speed hammers impact, shear, and squeeze the chips to refine them. Anti-stick lining prevents clumping, and a screen selects wet wood chips with a particle size of 3-8mm and a fiber length of 5-15mm, increasing their surface area for subsequent compression. If the wet wood chips have a moisture content exceeding 20%, a dryer is required to dry them to a moisture content of between 10% and 15%. The conveying process uses screw conveyors or belt conveyors to deliver the raw materials at a constant speed. A magnetic separator removes metal impurities and prevents wear.

The core forming system achieves compression and final shaping. A feeding device delivers the pretreated dry wood chips into the pelletizer to prevent blockage and underfilling. A motor drives the rollers to rotate, squeezing the sawdust into a die with shaped holes. The pressure softens the lignin in the sawdust and tightly binds the fibers. The transmission system ensures stable roller power, uniform extrusion pressure, and consistent pellet density. Finally, a cutting device cuts the wet sawdust squeezed from the die holes into a set length, completing the production of high-density pellets.

2. Characteristics of wet wood chips biomass pellet processing equipment

(1)High efficiency and energy saving: The wet wood chip pellet machine can process waste materials such as sawdust into pellet fuel, which not only reduces environmental pollution but also realizes the recycling of resources and greatly improves energy utilization efficiency. 

(2)Multifunctionality: In addition to processing biomass fuel, the wet wood chip pellet machine can also process animal feed, organic fertilizer, etc., and is widely used in agriculture, breeding and other fields. 

(3)Advanced pelletizing technology: The wet wood chip pellet machine adopts advanced pelletizing technology, which can automatically control parameters such as water addition and temperature during the pelletizing process, greatly reducing production costs and making the production process more economical and environmentally friendly.

(4)High-quality components: The main shaft and the connected hollow shaft of the wet wood chip pellet machine are made of alloy structural steel imported from Germany through water forging, rough turning, heat treatment, fine turning and fine grinding. The reasonable structure and uniform hardness improve the fatigue resistance and wear resistance of the components, providing more reliable guarantee for safe operation.

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

(1)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.

(2)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.

(3)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.

(4)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.

The wet wood chip biomass pellet project utilizes agricultural and forestry waste resources to convert wet wood chips with a moisture content of 15%-35% into clean energy and industrial raw materials. This environmentally friendly project aligns with the "dual carbon" goals and resource recycling needs, possessing significant economic and ecological value.

The project's raw materials are sourced from a wide range of low-cost sources, primarily including sawn wood and sanding sawdust from timber processing plants, wet branches and chips left over from logging, and wet fruit tree branches from orchard pruning. These raw materials are prone to rotting and pollution if left unused, or carbon emissions if incinerated. By recycling these materials, the project not only addresses solid waste disposal challenges but also reduces raw material procurement costs. Some regions are also eligible for agricultural and forestry waste recycling subsidies, further enhancing the project's economic viability.

Core production relies on wet wood chip pellet processing equipment, which is tailored to the characteristics of wet materials. Through pretreatment and core forming, the wet wood chips are processed into high-density pellets. The pretreatment stage ensures the appropriate moisture content of the raw materials through low-temperature drying or the addition of forming aids. The forming stage utilizes mechanical extrusion to soften the lignin and bind the fibers, resulting in pellets with uniform particle size and high density, meeting the needs of various scenarios.

The project's products have diverse applications. The core product, biomass pellets, can be used as a clean energy source, replacing coal for factory heating, biomass power plants, and home heating, achieving a combustion efficiency of over 85% and reducing carbon emissions by over 50% compared to coal. They can also be used as industrial raw materials for the production of fiberboard and particleboard in the wood-based panel industry, and for the paper industry to reduce transportation costs and ensure pulping uniformity. Furthermore, the pellets can be processed into organic mulch for water conservation and weed control in agriculture and forestry.

The product's performance is highly adaptable and suitable for diverse applications. It can replace coal for factory heating, generate electricity in biomass power plants, and meet heating needs in greenhouses and homes. The pellets have a regular shape and are less prone to moisture absorption and loosening, eliminating the need for complex moisture-proofing during storage. Transportation costs are over 60% lower than for loose wet wood chips, making them suitable for energy use at various scales.

The product offers high production flexibility and adaptability to regional needs. Wet wood chip processing does not require large-scale drying equipment, allowing small and medium-sized production lines to be put into operation, making it suitable for towns and counties with abundant agricultural and forestry resources. The production process can be flexibly adjusted based on the moisture content of the raw materials (for example, by adding a small amount of forming aids) to ensure consistent pellet quality. This not only provides localized clean energy for the region, but also drives the development of the surrounding agricultural and forestry waste recycling industry, creating a virtuous cycle of "resources, energy, and economy."
