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

The core equipment in pallet pellet processing is the biomass ring die pelletizer, which utilizes a combination of mechanical extrusion, frictional heating, and fiber self-bonding. The specific process is as follows:

During the extrusion process, rollers exert a pressure of up to 50-150 MPa on the powder, forcing it from its loose state (density 0.15-0.3 g/cm³) into the die's forming hole, forming a cylindrical column.

As the powder moves through the hole, it creates intense friction with the hole walls. Frictional heating raises the column temperature to 100-120°C, completely melting the softened lignin and hemicellulose, forming a natural adhesive that tightly binds the surrounding wood fiber particles together.

At the same time, the high temperature and pressure also remove some free moisture from the material (reducing the final pellet moisture content to 10%-15%) and rearranges the wood fiber structure, forming a high-density, high-strength column (density increased to 0.8-1.2 g/cm³).

2. Characteristics of wet wood pallets biomass pellet processing equipment

(1)Multiple Models to Meet Different Production Needs

As the core equipment, the wood pallet pellet machine offers a variety of models, allowing for flexible selection based on production volume and improved efficiency.

(2)Complete Production Line Compatibility

Wood pallet pretreatment equipment and pelletizing equipment complete the production line. For example, if pellet processing requires a raw material moisture content below 10%, the wet raw material must be pre-treated in a dryer to ensure the quality of the wood pallet pellets.

(3)Versatile Processing Adaptability

Wood pallets of varying specifications can be crushed and pelletized to meet diverse production needs.

(4) High-Precision CNC System

The electronic control system utilizes PLC control and automated operation via a touchscreen, achieving high precision and significantly reducing manual error.

(5) Durable Structural Design

TONY's processing equipment is sturdy and non-deformable; the support structure ensures long-term stable operation and extended service life.

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

Project Startup Suggestions

1. Preliminary Research: First, visit local logistics parks and factories to confirm the monthly supply of discarded wood pallets (the raw material volume must meet "production capacity x 1.2" to avoid idle capacity). Simultaneously, contact two to three potential customers (such as nearby food factories and heating companies) and sign letters of intent for supply.

2. Pilot Operation: If funding is limited, start with a "small-scale project" (1 ton per hour) and spend 6-12 months validating raw material supply, customer stability, and profit margins before gradually expanding production.

3. Long-Term Planning: Once stable operations are achieved, the industry chain can be expanded—for example, by building a dedicated logistics fleet (to reduce transportation costs), developing customized pellets (such as "low-ash pellets" for fireplace users, which increase unit prices), or building a small biomass heating station (to directly supply steam to surrounding factories, resulting in higher profits). In summary, the project of processing wooden pallets into biomass pellet fuel is suitable for entrepreneurs or small and medium-sized enterprises with local resources (raw materials/customers) and medium-sized capital. The key is to control raw material costs, bind stable customers, and ensure environmental compliance to achieve sustainable profitability.

As biomass pellet fuel or industrial auxiliary material, wood pallet pellets offer stable physical and chemical properties, and their user experience surpasses traditional loose wood and coal. Specifically, they demonstrate the following:

1. High energy density and excellent combustion efficiency

After compression molding, wood pallet pellets achieve a density of 1.1-1.3g/cm³ (much higher than the 0.4-0.6g/cm³ of loose wood), a volume reduction of 6-8 times, and a calorific value per unit volume of 4200-4800kcal/kg (similar to medium-quality coal). They also resist slagging during combustion (due to the low ash content of 1%-3% found in softwood, wood pallets are primarily made of softwood). Their thermal efficiency is over 30% higher than that of loose wood, making them suitable for use in boilers, fireplaces, hot air furnaces, and other equipment.

 2. Convenient Storage and Transportation, Low Cost

The pellets have a regular shape (mostly cylindrical, 6-10mm in diameter and 10-30mm in length) and good fluidity. They can be transported in bags, silos, or conveyor belts, and are resistant to moisture and deformation. They require only one-fifth the storage space of bulk wood of the same thermal mass, and there's no concern for insect infestation or mildew (the high temperatures during the pelletizing process kill insect eggs and mold), reducing labor and space costs during storage and transportation.

3. Low Entry Points, Wide Adaptability

Wood pallet pellets can be directly used in automated biomass combustion equipment (such as pellet stoves and biomass boilers). No complex pre-processing (such as chopping or pulverizing) is required; simply feed the pellets at a constant rate through a feeder. Operation is simple, making them suitable for industrial heating, home heating, agricultural greenhouse insulation, and other applications. They can also serve as an auxiliary fuel in biomass power plants.
