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

The essence of wet wood chip pellet processing equipment is to "use mechanical high pressure as a driving force, with lignin (a natural binder) and water (an auxiliary bonding agent) as the bond, through a continuous process of 'crushing - extrusion - cutting - cooling' to transform loose wet wood chips into high-density, easily storable solid pellets." Its key advantage lies in its adaptability to wet materials. By optimizing die gaps, controlling frictional heat, and implementing a supporting cooling system, it avoids mold sticking and clogging caused by wet materials during processing. It also utilizes the moisture in the wet material to reduce extrusion resistance and lower equipment energy consumption.

2.Characteristics of wet wood chips biomass pellet processing equipment

(1)Precise machining accuracy: The main housing is made of high-quality steel, with uniform thickness and compact structure; it is carefully machined by imported CNC machining centers, with zero machining accuracy, providing stronger support for normal operation.

(2)Reliable lubrication system: The bearings and oil seals used in the transmission part are all made of high-precision bearings and wear-resistant and temperature-resistant fluororubber oil seals, and a special automatic lubrication system is added, with oil circulation cooling and automatic timed lubrication to ensure that the bearings are fully lubricated and the operation is safer and more reliable.

(3)Durable ring die: The ring die is made of precision and has a unique compression ratio design, which makes the product quality better and the service life of the ring die longer, minimizing the production cost.

(4)Continuous operation capability: The new generation of biomass pellet mill can achieve 24-hour continuous operation

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

The deployment of wet wood chip pellet processing equipment essentially adheres to the dual principles of "raw material proximity + product proximity"—needing proximity to both wet wood chip production sites (to reduce raw material transportation costs) and pellet demand (to reduce product transportation costs). Therefore, it is primarily concentrated in the following areas:

Wood/furniture industry clusters

Regions rich in forestry resources (such as northern heating areas and biomass power plant clusters);

Cities with strict environmental protection policies and a high demand for solid waste recycling

Across these scenarios, the key is to achieve efficient conversion from wet wood chips to high-value pellets.

TONY Brand 40-50Ton/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.

Advantages of the Wet Wood Chip Pellet Processing Project

1.Technical Advantages:

Advanced Equipment: Currently, a variety of advanced wet wood chip pellet processing equipment is available on the market, featuring high automation, high production efficiency, high pellet forming rates, and low energy consumption.

Mature Process: The production process for wet wood chip pellet processing is relatively mature. Through pretreatment, drying, crushing, pelletizing, cooling, and screening, wet wood chips can be converted into pellet products that meet quality standards. For example, the TONY pellet machine utilizes a ring die structure, features automatic variable frequency feeding, and hydraulic pressure regulation on the pressure rollers, achieving a pellet forming rate exceeding 98%.

2.Economic Benefits:

Cost-Effectiveness: The project's costs primarily include raw material procurement, equipment investment, energy consumption, and labor costs. If raw material costs and other expenses are properly controlled, the project will achieve high cost-effectiveness.

Revenue: The selling price of wood pellets varies depending on market demand and product quality.

3.Environmental Benefits:

Reduced Forest Resource Depletion: By converting agricultural and forestry waste and waste wood into wood pellets, the project effectively reduces the depletion of natural forest resources and contributes to the recycling of forestry resources.

Reduce Carbon Emissions: The amount of carbon dioxide emissions generated during the combustion of wood pellets is roughly equivalent to the amount of carbon dioxide absorbed during the growth of trees. Wood pellets are low-carbon energy, which helps reduce greenhouse gas emissions and promote the optimization of energy structure and green and low-carbon transformation.

Wood pellets have a wider range of applications than traditional loose wood chips, meeting energy needs across various sectors: industrial, residential, and power generation.

1.Industrial:

As a fuel for industrial boilers (e.g., in the food processing, textile, and chemical industries), they replace coal and natural gas, reducing energy costs. Some high-purity pellets can also be used in biomass gasification power generation and heating projects.

2.Residential:

Suitable for home biomass fireplaces and heating stoves for winter heating. They burn odorlessly and produce minimal smoke, making them cleaner than coal and more economical than electricity (especially in rural areas of northern China, where they are widely used under the "coal to biomass" policy).

3.Power generation:

Large-scale biomass power plants use wood pellets as their core fuel, directly burning them to generate electricity and connect them to the grid. They are an important supplement to renewable energy generation (e.g., some power plants in Europe and China have already implemented them on a large scale).

4.Other applications:

Wood pellets can also be used as animal bedding (water absorption and deodorization), as an auxiliary material for organic fertilizer fermentation, and as a filler in new building materials (such as lightweight insulation), expanding their non-energy applications.
