The working principle of wet wood log biomass pellet processing equipment

The core principle of wet wood pellet processing equipment is to produce pellets through extrusion. First, wet wood chips with a high moisture content (usually kept within an appropriate range to avoid being too wet or too dry) are fed into the equipment's crushing or pretreatment unit for initial crushing and mixing to achieve a more uniform texture. The treated wet wood chips are then conveyed between the pelletizer's rollers and a ring die (or flat die). The rotating rollers press the pellets, subjecting them to immense pressure within the die holes of the ring die (or flat die), compressing them into pellets of a defined density and shape. Finally, the pellets are cut and (in some equipment) cooled before processing is complete.

2. Characteristics of wet wood log biomass pellet processing equipment

(1) Strong adaptability: It can directly process wet sawdust with high moisture content without the need for complex pre-drying processes, thus reducing the initial processing costs.

(2) Good molding effect: Through high-pressure extrusion, wet sawdust pellets can have high density and strength, are not easy to break, and are easy to store and transport.

(3) High degree of integration: Some equipment integrates functions such as crushing, conveying, pelletizing, and cutting, realizing integrated processing and saving operation steps.

(4) Relatively reasonable energy consumption: Designed based on the characteristics of wet materials, the material's own moisture can be used to assist in molding during the extrusion process. Compared with equipment that processes dry materials, it has more energy consumption advantages under certain conditions.

(5) Convenient operation: Most of them use automated control systems, which can easily adjust parameters such as particle size and output, making it suitable for continuous production.

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

(1) Biomass energy: Processing wet sawdust into pellet fuel for boiler combustion, biomass power generation, etc., replacing traditional fossil energy and reducing carbon emissions.

(2) Agricultural and forestry waste treatment: Processing wet sawdust, branch debris, etc. generated in agricultural and forestry operations. The pellets produced can be used as organic fertilizer raw materials or livestock bedding, achieving recycling.

(3) Environmental engineering: Used to process wet sawdust waste generated by industries such as wood processing and furniture manufacturing, reducing landfill volume and reducing environmental pollution risks.

(4) Small processing sites: Suitable for on-site processing of wet sawdust in small and medium-sized wood processing plants, forest farms, etc., avoiding the costs of raw material transportation and drying, and improving resource utilization efficiency.

TONY Brand 40-50 Ton/Hour Wet Wood Log Pellet Manufacturing Plant can take wet wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood as the main raw material. After pretreatment and processing, it 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.

1.Outstanding Environmental Benefits:

Biomass pellets primarily produce carbon dioxide and water during combustion, with minimal emissions of pollutants such as sulfur dioxide, nitrogen oxides, and dust. Furthermore, because the raw materials absorb carbon dioxide during growth, they are nearly "zero-carbon" throughout their lifecycle, offering high environmental value.

2.Quick Return on Investment:

The investment threshold for this project is relatively low. A small pellet machine can be operational within a day. If the equipment produces 10 tons per day, with an ex-factory price of 800 to 1,100 yuan per ton, the net profit can reach 3,000 yuan per day, typically achieving a payback period of 3-6 months.

3.Excellent Product Characteristics:

After processing and forming, biomass pellets significantly increase their energy density, making them easier to store and transport. Their regular shape and stable chemical composition provide a stable flame during combustion, with a calorific value generally ranging from 3,500 kcal/kg to 5,000 kcal/kg and a combustion efficiency of 97%, meeting various heating and power generation needs.

1.Storage and transportation advantages

(1) High density and easy storage:

After compression molding, the volume is greatly reduced, which is convenient for storage and not easily affected by moisture and deterioration.

(2) Convenient transportation:

The regular shape facilitates mechanized loading and unloading and transportation, reducing logistics costs.

2.Application scenario advantages

(1) Wide range of applications:

It can be used in industrial boilers, biomass power plants, home fireplaces, agricultural greenhouse heating and other scenarios, replacing traditional energy sources such as coal and natural gas, with high application flexibility.

(2) Convenient use:

It can be fed through automated equipment, is easy to operate, and is compatible with many existing combustion equipment, without the need for large-scale equipment modification.
