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

Wet wood pellet processing equipment is key to converting wet wood chips into uniform, dry, and storable wood pellets. Its operating principle generally includes four core stages: crushing, drying, compression molding, and cooling. The entire process is designed to increase the density of the raw material, reduce its moisture content, and enhance its performance as a biomass fuel or other applications.

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

(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: converts wet 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: prevent wet 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.

Key Technical Solutions and Production Process for the Wet Wood Chip Pellet Project

1.Pretreatment Technology

Wet wood chips undergo three core processes: crushing, drying, and pelletizing:

Drying: Hot air is used to reduce the moisture content of the wet wood chips from 40%-60% to 10%-15%. This process accounts for 30%-40% of energy consumption and requires a waste heat recovery system to optimize energy consumption.

Pelletizing: A ring die pelletizer is used to press the crushed wood powder into pellets under high temperature and pressure. Key parameters include die hole diameter (typically 6-12mm), forming pressure (50-100MPa), and production temperature (80-120°C).

2.Automation and Intelligent Upgrades

Based on industry technology development trends, the project can incorporate an intelligent manufacturing system. This system dynamically adjusts production parameters through real-time monitoring of moisture content, pellet density, and other data, reducing manual intervention and improving product stability. This will increase production efficiency and reduce defective product rates.

Biomass pellets are a solid fuel made from processed biomass materials such as wood chips. They have the following characteristics:

1.Uniform Size:

Biomass pellets typically range from 6-10 mm in diameter and 10-50 mm in length. This uniformity makes them more stable and efficient during combustion.

2.Low Moisture Content:

The moisture content of biomass pellets is typically below 10%, which helps improve combustion efficiency and reduce smoke and pollutant generation.

3.High Energy Density:

Due to their high density, biomass pellets also have a relatively high energy density, meaning they can provide more calories per unit volume.

4.Easy Storage and Transportation:

Due to their small size and high density, biomass pellets take up less space during storage and transportation, resulting in relatively low transportation costs.

5.Environmentally Friendly:

Biomass pellets produce low smoke and carbon dioxide emissions during combustion, making them a more environmentally friendly fuel option.

6.High Combustion Efficiency:

The high energy density and low moisture content of biomass pellets ensure more complete combustion, with thermal efficiencies generally exceeding 94%. 

7.Wide Application:

Biomass pellets are suitable for environments with high environmental requirements, such as food processing plants and pharmaceutical factories. They are also suitable for industrial production lines requiring efficient heat output, such as drying equipment and steam boilers.

In summary, biomass pellets, as a fuel processed from wood chips, offer uniform size, low moisture content, high energy density, ease of storage and transportation, excellent environmental performance, high combustion efficiency, and a wide range of applications.
