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

The operating principle of the wet pallet biomass pellet processing equipment can be briefly described as follows: Using high-moisture waste wet pallets as raw material, the equipment transforms the loose wet material into high-density biomass pellets through four core steps: pre-treatment, crushing, nail removal, pulverization, drying, and extrusion molding. The specific process is as follows:

Pre-treatment and impurity removal: Metal nails and other impurities are removed from the wet pallets by crushing equipment, breaking the pallets into wood chips approximately 5 cm in size.

Pulverization and refinement: The crushed wood chips enter a pulverizer (such as a hammer or blade type) and are crushed into uniform wood chips with a particle size of 3-5 mm, providing the appropriate particle size for subsequent extrusion molding. Drying and conditioning: A drum dryer is used to reduce the moisture content of the wet wood to 10%-15% (the optimal moisture content for subsequent molding).

Extrusion molding: The finely pulverized wood chips are fed by a screw conveyor into a ring die (or flat die) pelletizer, where they are heated at high temperatures (heat generated by extrusion friction, reaching a temperature of 100-150°C). The biomass pellets are squeezed into cylindrical particles through the forming holes in the mold under the action of high pressure (70-100℃) and finally cut into fixed lengths (usually 6-10mm) by a cutter. After cooling, the finished biomass pellets are obtained.

2. Characteristics of wet wood pallets biomass pellet processing equipment

Strong Adaptability to Wet Materials: Addressing the high moisture content of wet pallets, a high-power hot air drying system is equipped to quickly reduce the raw material moisture content to the optimal molding range of 10%-20%, while preventing wet material from sticking to the equipment and clogging the conveyor.

Efficient Impurity Removal and Protection: Built-in metal detection and magnetic separation modules precisely separate metal impurities such as nails and wire from the pallets. The crushing and forming components are constructed of wear-resistant materials to prevent impurities from scratching the molds or damaging the transmission mechanism, extending the equipment's service life.

Flexible Raw Material Processing: Adaptable to the irregular shapes of waste pallets, the pre-processing stage uses a shredder to break down large pieces into smaller pieces. An adjustable-speed pulverizer then refines the material into uniform 3-5mm chips. This system is compatible with pallets of varying thicknesses and materials, such as pine and poplar. High Forming Stability: Utilizing a ring die/flat die dual-roller structure, coupled with extrusion friction heating (70-100°C), the high temperature softens wood fibers and improves pellet adhesion. The adjustable pressure system adapts to varying sawdust moisture levels, minimizing pellet cracking and loosening. Finished product density can reach 1.1-1.3g/cm³.

Environmentally Friendly and Energy-Saving: The drying process utilizes waste heat from biomass fuel generated during the forming process for auxiliary heating, reducing external energy consumption. The entire machine is equipped with a sealed dust collection device to reduce sawdust pollution, complying with environmental emission requirements and enabling the recycling of waste wooden pallets.

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

Waste Pallet Recycling and Processing

This equipment is suitable for logistics parks, warehouses, e-commerce distribution centers, and other locations that generate large quantities of waste, wet pallets. In these scenarios, the equipment can directly convert accumulated wet pallets (including those soaked in rainwater or damp in storage) into high-density biomass pellets, resolving the issues of wet pallets being difficult to store, prone to mold, and high recycling and transportation costs, achieving "on-site processing, turning waste into value."

Biomass Energy Production

This equipment can be used as specialized processing equipment in biomass pellet plants, specifically targeting wet pallets as a raw material. The pellets produced can be used as fuel for industrial boilers (replacing coal), as feedstock for biomass power plants, or processed into residential heating/cooking fuel. It is particularly suitable for small and medium-sized pellet plants located near the pallet recycling source, reducing raw material procurement and transportation costs.

Agriculture and Forestry

This equipment is suitable for farms, forestry farms, wood processing workshops, and other locations with large quantities of waste pallets. For example, farms can process wet wood pallets into pellets for greenhouse heating and agricultural machinery fuel; forest farms can combine the wet waste generated by their own wood processing with wet wood pallets to improve their self-sufficiency in biomass energy and reduce their dependence on purchased fuel.

TONY Brand 1-1.5 Ton/Hour Wet Wood Pallets Pellet Manufacturing Plant can take wet wood pallets, 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.

With growing environmental awareness and the depletion of fossil fuels, biomass energy has become a key direction for global energy development. Biomass pellets, with their high calorific value, low pollution, and easy storage, continue to see increasing market demand. Discarded wood pallets, as a wood waste material, offer a stable supply, and processing them into biomass pellets aligns with the needs of a circular economy and environmental policies.

1.Easy to obtain:

Wood processing companies and the logistics and warehousing industries produce large quantities of discarded wood pallets annually, at low cost. In some areas, collection is even free, reducing raw material costs.

2.Good economic benefits:

Biomass pellets can be used in industrial boilers, heating, and power generation, generating significant demand both domestically and internationally. Projects like Xingwen County Four Seasons Wood Industry Co., Ltd.'s 8 million yuan investment project can achieve an annual production capacity of 10,000 tons of biomass pellet fuel.

3.Significant environmental benefits:

This allows for waste recycling, reduces pollution from incinerating or landfilling wood pallets, and reduces reliance on fossil fuels. Carbon dioxide emissions from combustion approach carbon cycle equilibrium, contributing to mitigating the greenhouse effect.

1.Widely available and low-cost raw materials. 

Discarded wooden pallets are a common waste material in logistics, warehousing, wood processing, and manufacturing, generating significant quantities annually (e.g., discarded pallets from e-commerce and machinery companies). This raw material eliminates the need to purchase additional wood and can often be recycled at a low price. In some areas, collection is even free (companies are willing to pay for the removal of discarded pallets, even though they need to dispose of them). This significantly reduces raw material procurement costs and ensures project profitability.

2.Raw material pre-processing is relatively easy.

Wooden pallets are primarily made from common hardwoods or softwoods, such as pine, fir, and poplar. Their fiber structure is intact, requiring no complex sorting (only impurities like nails and plastic need to be removed). They can be directly crushed and processed, resulting in low energy consumption and high efficiency.

3.Strong raw material supply stability.

The logistics industry has a long-standing demand for wooden pallets, and the generation of discarded pallets has steadily increased with the scale of logistics. By establishing long-term recycling agreements with warehousing companies and manufacturing plants, a stable raw material supply chain can be established, avoiding the risk of running out of material to process.
