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

The core function of dry wood pellet processing equipment is to compress dried wood raw materials (such as sawdust, wood powder, and straw) into high-density pelletized fuel or material. Its operating principles primarily include the following key steps:

Raw material pretreatment: First, the dry wood is crushed to break down large pieces of wood into uniform sawdust or wood powder, ensuring a consistent particle size for subsequent compression.

Extrusion: The raw material is fed into the pelletizer's ring or flat die. The high-speed rotation of the rollers applies pressure, squeezing, rubbing, and heating the material within the die. The high temperature softens the wood fibers and allows them to bind tightly together, ultimately extruding them through the die to form cylindrical pellets.

Cooling and screening: The pellets, freshly extruded, are hot and need to be cooled to room temperature in a cooler to prevent mold. They are then screened to remove debris and impurities, resulting in a qualified product.

2. Characteristics of dried wood log biomass pellet processing equipment

Precisely matched to dry wood properties: Designed specifically for dry sawdust, wood scraps, dry branches, and other materials with a moisture content of 8%-15%, this machine eliminates the need for additional large-scale drying equipment (only a simple conditioning device is used to fine-tune the moisture content when the material moisture content is slightly lower). This avoids the high energy consumption and clumping associated with wet wood processing.

Compatible with a wide range of wood materials: It can process dry wood of varying hardness, including softwoods (pine and fir) and hardwoods (birch and oak). By flexibly adjusting the pulverizer blade material (high-carbon steel wear-resistant blades for hardwood) and the forming roller pressure, it ensures stable crushing efficiency and forming results, achieving a material utilization rate exceeding 95%.

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

Biomass Energy:Provides raw materials for biomass power plants, heating companies, and industrial boilers (such as those in food processing and textile mills). It converts dry wood into high-density pellet fuel, replacing traditional energy sources like coal and natural gas and reducing carbon emissions. It can also be used as fuel for household heating stoves and fireplaces, meeting clean heating needs.

Wood Processing and Furniture Industry:Processes dry sawdust, scraps, shavings, and other waste generated by furniture and wood processing plants into pellets. These can be recycled as fuel for in-plant boilers or sold externally, transforming waste into a resource and reducing solid waste disposal costs.

Agriculture and Animal Husbandry Support:First, it processes agricultural and forestry waste such as dry straw and branches into pellets for use as bedding for livestock and poultry (e.g., cowshed and chicken coop bedding, which is highly absorbent and easy to clean). Second, some equipment can process a mixture of dry sawdust and feed ingredients to produce simple biomass feed carrier pellets to aid animal husbandry production. Environmental Protection and Solid Waste Treatment:

For forestry pruning waste, such as dry branches and wood processing waste, this equipment compresses loose waste into high-density pellets, reducing transportation and storage space while also preventing environmental pollution caused by indiscriminate waste stacking, effectively turning waste into treasure.

1.Strong policy support:

With the ongoing advancement of the "Dual Carbon" strategy, China has introduced a series of policies to encourage the development and application of biomass energy. For example, the "14th Five-Year Plan for Renewable Energy Development" explicitly supports this sector, creating a favorable policy environment for biomass pellet processing projects.

2.Abundant raw material resources:

The raw materials for biomass pellets primarily consist of agricultural and forestry waste, such as straw, sawdust, rice husks, and peanut shells. These sources are widespread, and in some areas, these raw materials are even available free of charge, effectively reducing procurement costs.

3.Strong market demand:

Biomass pellets can be used for industrial heating, residential heating, power generation, animal husbandry, and other applications. With increasing environmental protection requirements, traditional coal-fired boilers are gradually being phased out. Demand for biomass pellets is rapidly growing in areas such as industrial boiler renovation, biomass heating, and power plants.

1.Wide range of sources and low cost:

The raw materials are mainly forestry waste such as wood chips, scraps, branches, and bark generated by wood processing. These materials are available in large quantities in wood processing plants, furniture factories, and other places. Some can be obtained at low prices or even for free, which can effectively control the cost of raw materials.

2.Strong sustainability:

It is a renewable resource. As long as trees are harvested and planted reasonably, a continuous supply of raw materials can be achieved, which is in line with the concept of green development.

3.High and stable calorific value:

The calorific value of wood chip pellets is usually 4000-5000 kcal/kg, and the combustion efficiency can reach more than 90%. It can provide heat stably to meet the needs of industrial heating and household heating.

4.Complete combustion and low pollution:

The pollutants such as sulfur dioxide and nitrogen oxides produced during combustion are much lower than those of coal, and the amount of ash is small, which has little impact on the environment and meets environmental protection standards.
