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

Pelletizing equipment is the core of pellet processing. It mechanically compresses dried wood chips into dense cylindrical pellets.

(1)Core equipment: Ring die pellet machine (mainstream).

(2)Ring die pellet machine principle:Dried wood chips enter the pelletizing chamber through a feeder and are pushed between the ring die and the press rollers by a stirring paddle.

The ring die (with evenly distributed holes in the inner wall, 6-12 mm in diameter) is stationary, while the press rollers (two to three with a patterned surface) rotate at high speed, applying pressure (up to 50-100 MPa) to the wood chips.

Under high pressure, the wood fibers undergo plastic deformation and hydrogen bonding (no adhesive is required; the wood's own lignin softens under the heat generated by the extrusion friction, acting as a natural adhesive). The wood chips are then extruded through the die holes to form continuous cylindrical strips.

The strips are cut by a cutter on the outside of the ring die, forming pellets 20-50 mm in length.

2. Characteristics of wet wood log biomass pellet processing equipment

(1) Broad spectrum processing capability: Processable raw materials include wood (logs, wood chips, sawdust), crops (straw, rice husks, corn cobs), herbs (reeds, forage grass), etc. By adjusting the crushing and pulverizing parameters, it can adapt to raw materials of different hardness and fiber content (for example, hardwood requires stronger crushing capacity, and straw needs to control the pulverization particle size to prevent agglomeration).

(2) Clear requirements for raw material pretreatment: The raw material moisture content must be controlled at 8%-15% (too high will easily cause adhesion and mold clogging, too low will result in insufficient particle strength), and the particle size is usually required to be 1-3mm. Therefore, the equipment system often integrates drying and screening modules to ensure that the raw materials meet the standards. 

3. Modularization of core equipment and continuous production process

(1) Modular combination: A typical production line consists of "crushing equipment (coarse crushing) → grinding equipment (fine crushing) → drying equipment (humidity control) → granulating equipment (molding) → cooling equipment (cooling) → screening equipment (selection) → packaging equipment". Each module can be flexibly increased or decreased according to production capacity requirements (for example, some auxiliary equipment can be omitted for small production lines).

(2) Continuous operation: Through the connection of various links such as conveyor belts and screw feeders, automated continuous production from raw material input to finished product output is achieved.

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

(1)Industrial Energy: Processing equipment provides fuel (replacing coal and oil) for factory boilers and kilns, such as steam boilers in textile and food factories, and heating kilns in the ceramic and building materials industries. This stable production of pellets ensures energy supply.

(2)Power Generation:Biomass power plants require large quantities of standardized pellets as fuel. Large-scale processing equipment can meet the power plants' stringent requirements for pellet calorific value and density, ensuring combustion efficiency and stable power generation.

(3)Agriculture and Animal Husbandry: Some processing equipment can produce pellets for livestock bedding (such as straw pellets) or raw material pellets for organic fertilizer production. The equipment can be adapted to different agricultural needs by adjusting the process.

(4)Residential Heating:For pellets used in home fireplaces and small heating appliances, processing equipment must control pellet size and hardness to accommodate residential combustion equipment. The equipment's refined production capacity directly impacts the user experience of these pellets.

(5)Environmental Protection and Waste Management:In garbage and sewage treatment plants, processing equipment can convert organic waste (such as sludge and food waste) into fuel pellets for resource utilization. Corrosion- and clogging-resistant designs are key.

TONY Brand 18-20 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.

1.Significant Economic Benefits:

The selling price of biomass pellets is relatively high, but after deducting equipment depreciation, factory rental, transportation costs, and taxes, the monthly net profit is substantial.

2.Mature and Stable Technology:

Biomass pellet production technology is relatively mature. The entire production line adopts a modular design, supporting automated feeding, crushing, drying, pelletizing, cooling, and packaging, reducing manual labor. The core pelletizer can operate continuously for over 12 hours without clogging, achieving a pelletizing rate of over 98%. By optimizing the compression ratio and power matching, power consumption per ton is less than 55 kWh, saving over 15% energy compared to traditional equipment.

3.Outstanding Environmental Advantages: 

Biomass pellets produce low carbon dioxide emissions during combustion, essentially achieving zero emissions. They also contain very low levels of sulfur oxides, nitrogen oxides, and dust, helping to mitigate the greenhouse effect, improve air quality, reduce environmental pollution, and meet environmental requirements.

4.Easy Storage and Transportation: 

After compression molding, biomass pellets have a higher density and a more regular shape, making them easier to store and transport. This reduces storage and transportation costs, improves the efficiency of biomass energy, and enables their application in a wider range of regions.

Biomass pellet fuel refers to a granular fuel made by using crops (such as straw), wood (such as wood, pine, fir, etc.), sawdust and other agricultural and forestry processing waste (such as rice husks, tree bark, furniture factory foot feed, wood powder, cotton poles, peanut shells, medicinal residue, bamboo chips, sludge, building formwork, wooden pallets, etc.) as raw materials. After being extruded by a biomass pellet machine, the crushed raw materials are made by cold compact molding and processing under normal temperature conditions using a press roller and ring mold.

1.Density: The density of raw materials is generally 0.1 - 0.13t/m³, and the particle density after forming is 1.1 - 1.4t/m³. It has a large density and small size, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass.

2.Shape: granular.

3.Odor: During the production process, no additives can be added, so the original smell of its raw materials is still maintained.

4.Elemental composition: 75-85% carbon content, 3-6% ash content, 1-3% moisture content, absolutely no impurities such as coal gangue, stones, etc. that do not heat and consume heat, and do not contain thiophosphate.

5.Catalyst value: The biomass pellet fuel generates a large amount of heat, with a heat generation of around 3900-4800 kcal/kg. The calorific value of the pellet fuel made from different raw materials varies. For example, larch particles are about 4022 kcal (16829kj/kg), red pine particles are about 3978 kcal (16645kj/kg), wood chip mixed particles are about 3896 kcal (16302kj/kg), and wood chip peanut shell particles are about 3812 kcal (15948kj/kg). The fuel calorific value produced by general biomass pellet fuel manufacturers is about 4100±100Kcal/Kg, and 1 ton of biomass pellet fuel is equivalent to 0.55-0.6 tons of standard coal or 0.4 tons of diesel/fuel oil
