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

Core Forming: Fiber reorganization and densification through mechanical extrusion is a key step in convertingdried  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 thedried  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 todried  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 dried wood chips biomass pellet processing equipment

Wood pellet processing equipment (i.e., wood biomass pellet machines and supporting production lines) is specifically designed to convert wood materials such as wood chips, sawdust, shavings, and branches into high-density pellets.

It is compatible with a wide range of wood materials: wood chips, wood chips, sawdust, shavings, grain husks, branch debris, and waste wood. After pretreatment (crushing and grinding), both softwoods like pine and fir and hardwoods like oak and birch can be efficiently processed.

Managing raw material moisture fluctuations: Dedicated drying equipment (such as drum dryers) can control the moisture content of wood raw materials to 10%-15% (the optimal moisture range for wood pellet production), avoiding problems such as clogging and loose pellets caused by excessive moisture.

Flexible particle size control: The accompanying pulverizer can crush the wood raw materials to the size of sawdust, meeting the pellet machine's fineness requirements and ensuring uniform pellets.

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

The deployment of dried wood chippellet processing equipment essentially adheres to the dual principles of "raw material proximity + product proximity"—needing proximity to both dried wood chipproduction 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 dried  wood chips to high-value pellets.

1.Wood processing and furniture manufacturing industry clusters

Typical scenarios: solid wood furniture factories, plywood factories, wood flooring factories, and woodworking machinery factories;

Equipment function: convertsdried  waste wood that originally required payment for removal into biomass pellets that can be used for self-use or export (for example, furniture factories use pellets instead of natural gas to heat and dry wood, reducing energy costs).

2.Forestry felling and wood storage and transportation sites

Typical scenarios: forest farms, log purchasing stations, and wood transfer terminals;

Equipment function: preventdried  wood chips from becoming moldy and deteriorating during storage and transportation (especially in the rainy season). After being processed into pellets, the volume is reduced to 1/3-1/4 of the original size, reducing transportation costs by more than 60%, and can be sold directly to biomass power plants. 

3.Construction and renovation waste wood processing sites

Typical scenarios: building demolition sites, renovation waste treatment stations, and waste wood recycling plants;

Equipment function: Solve the problem of "wet waste wood being difficult to degrade and easy to pollute" (traditional treatment methods are mostly incineration or landfill, which pollute the environment) and convert it into clean pellet fuel, in line with the "construction waste resource utilization" policy requirements.
