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

The wet pallet biomass pellet processing equipment is used to remove nails from wet pallets and other biomass materials, shred them, and compress them into pellet fuel. Its working principle is to first crush the wet pallets to remove nails, then grind them into sawdust in a pulverizer. The dryer dries the wood to a moisture content of 10-15%, and then presses it into pellets in a pelletizer, ultimately producing biomass fuel pellets that meet quality standards.

2. Characteristics of wet wood pallets biomass pellet processing equipment

The  pellet processing equipment is a production line specifically designed for waste pallets (containing nails, metal connectors, and wood with uneven moisture and hardness). Its core features are tailored to the raw material characteristics, ensuring production efficiency, and optimizing finished product quality. The crushing stage processes the pallets into 25-55mm wood chips. The equipment design balances crushing efficiency with impurity tolerance. The pulverization stage processes pre-treated wood segments/chips into 2-5mm sawdust (the optimal particle size for pelletization). The drying stage controls moisture content and ensures pellet formation efficiency. The pelletizing stage forms the core and presses the powder into high-density pellets. The cooling and screening stages stabilize pellet properties and eliminate substandard products. The equipment in each stage works synergistically to transform raw materials into finished products.

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

Wood pellets (also known as "biomass pellet fuel") are a key alternative to traditional fossil fuels like coal and heavy oil due to their high combustion efficiency, low pollution emissions, and convenient storage and transportation. They are also the most popular application for wood pallet pellet processing equipment, including:

(1).Industrial Boiler/Kiln Fuel:Small and medium-sized boilers (steam boilers and hot water boilers) in the food processing, textile, chemical, and building materials industries, as well as heating equipment such as ceramic and glass kilns, can directly use wood pallet pellets (with a calorific value of approximately 4200-4800 kcal/kg, similar to medium-quality coal).

(2).Residential Heating/Household Energy:Wood pallet pellets can be used as fuel for household biomass heating stoves and fireplaces. The pellets burn stably (no black smoke or odor) and are automatically fed through a dedicated hopper, eliminating the need for frequent refills. Furthermore, some catering businesses (such as small restaurants) use them to replace liquefied petroleum gas for heating, reducing energy costs. 

(3).Power Plant Supplemental Fuel:Some biomass power plants mix wood pallet pellets with other biomass fuels, such as straw and sawdust, for power generation or combined heat and power (cogeneration) (generating both electricity and steam). The high density of wood pallet pellets (0.8-1.2 g/cm³) reduces transportation and storage space, lowering raw material storage costs for power plants. Furthermore, the high purity of the wood fiber (free of sand and impurities found in straw) reduces the risk of boiler slagging.

TONY Brand 48-60Ton/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.

For investors, it is better to give priority to regions with abundant raw materials and strong policy support. By locking in raw material supply, improving production capacity utilization and expanding high-end markets (such as exports and civilian use), the return cycle can be further shortened and rapid profits can be achieved.

Wood Pellet Processing Investment Costs

1.Equipment Investment: 

Equipment investment varies significantly depending on the project scale and equipment selected. A small semi-automatic production line may cost only tens to hundreds of thousands of yuan, while a large fully automated production line can cost millions or even more.

2.Plant and Site Costs: 

You need to select an appropriate plant and site based on your production scale. Rental or construction costs vary by region.

Raw Material Procurement and Transportation Costs: Raw material costs are affected by factors such as region, season, and raw material type, while transportation costs are related to the raw material sourcing radius and product sales range.

3.Environmental and Other Expenses: 

These include the investment and operating costs of environmental protection equipment, utilities, and employee salaries.

1.Environmental protection:

Wood pellet fuel has the characteristics of low carbon and low sulfur. Compared with coal, carbon dioxide emissions are reduced by 97.91%, sulfur dioxide emissions are reduced by 99.15%, and nitrogen dioxide emissions are reduced by 72.09%. Therefore, the emissions of biomass pellet fuel are almost zero compared to the high pollution emissions of coal. 

2.Renewable raw materials:

The main raw materials of wood pellet fuel are agricultural and forestry waste, such as branches, sawdust, straw, etc. These raw materials are not only cheap, but also renewable resources, which helps to achieve sustainable development.

3.High calorific value:

The calorific value of biomass pellet fuel reaches 3600-4200 kcal/kg. Using a special biomass heating furnace, the thermal efficiency can reach over 85%.

4.Cost-effectiveness:

The cost of wood pellet fuel is relatively low and the operating cost is not high. In addition, due to its environmental protection characteristics, it is supported by national policies, which also helps to reduce its use cost. 

5.Wide range of applications:

Wood pellet fuel can be used in many occasions, such as home heating, cooking, hot water supply and biomass power plants, etc.
