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

The core principle of wood pellet processing equipment (such as wood chip pellet machines) is to convert biomass feedstock into high-density pellet fuel through mechanical extrusion. The basic process includes three steps: feedstock pretreatment (crushing, drying, and screening), mechanical pressing, and finished product processing (cooling and packaging). For example, in a ring die pellet machine, a motor connected to a reducer via a coupling drives the ring die to rotate. Gravity forces the feedstock into the pressing zone, where the pressing rollers squeeze the material into the ring die holes. After being formed in the die, the pellets are cut into pellets of a fixed length by a cutter.

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

Processing equipment provides fuel for factory boilers and kilns (replacing coal and oil), such as steam boilers in textile and food processing plants, and heating kilns in the ceramics and building materials industries. Stable pellet production ensures energy supply.

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

(2)Residential Heating:For pellets used in home fireplaces and space heaters, processing equipment must control pellet size and hardness to accommodate residential combustion equipment. The equipment's refined production capabilities directly impact the user experience of these pellets.

(3)Environmental Protection and Waste Management:In waste and sewage treatment plants, processing equipment converts organic waste (such as sludge and food waste) into fuel pellets for resource recovery. Corrosion-resistant and clogging-resistant designs are crucial.

1. Outstanding Environmental Protection and Low Carbon Emissions

Carbon Neutral: Wood pellet fuel is derived from wood processing waste (such as wood chips and sawdust) and is a biomass energy source. The carbon dioxide absorbed during plant growth is roughly balanced by the carbon dioxide released during combustion, making it a "carbon-neutral" energy source, significantly reducing its contribution to the greenhouse effect.

Low Pollutant Emissions: Compared to coal, wood pellets produce extremely low levels of pollutants such as sulfur dioxide and nitrogen oxides (often far below environmental standards) when burned, and dust emissions are also low, effectively reducing air pollution and meeting increasingly stringent environmental regulations.

2. Wide Source of Raw Materials and Controllable Costs

Abundant Raw Materials: The main raw materials are scraps, wood chips, sawdust, branches, and bark generated during wood processing. These materials are readily available and stable in forestry, furniture manufacturing, and papermaking. They can even be "turned waste into treasure," reducing the environmental impact of landfills or incineration.

Cost Advantages: The raw materials are mostly industrial waste, resulting in relatively low procurement costs. Furthermore, some regions offer subsidies for biomass energy projects, further reducing production and usage costs. Compared to other energy sources like natural gas and fuel oil, biomass energy is economical.

3. High Combustion Efficiency and Efficient Energy Utilization

High Density: Wood pellets are compressed and formed, resulting in a density significantly higher than that of raw wood or sawdust (typically 1.1-1.3 tons/cubic meter). They are less prone to loosening during combustion, maintaining a stable combustion state and a long-lasting flame. They also offer high thermal efficiency (typically exceeding 85%, compared to the 40%-50% of loose firewood).

Stable Combustion: The pellets have a regular shape and uniform size, facilitating automated feeding and combustion control. They can be precisely adjusted with a matching pellet stove, reducing energy waste and making them suitable for applications requiring a stable heat source.

4. Convenient Storage and Transportation

Small Size: Compressed pellets are only 1/5-1/8 the volume of raw sawdust, significantly saving storage space. They can be stored in bags or in bulk, eliminating the need for specialized storage facilities, making them suitable for homes, businesses, and other environments.

Low Transportation Costs: The high density allows for higher energy transport per unit volume, improving transportation efficiency and reducing transportation costs. Furthermore, the pellets are resistant to moisture (some products are treated to prevent moisture), minimizing loss during transportation.

5. Diverse Application Scenarios

Civilian Applications: They can be used for home heating and cooking (using devices such as pellet fireplaces and pellet stoves). They are simple and clean to operate, replacing traditional coal and firewood to improve the indoor environment.

Industrial Applications: They can be used as boiler fuel to provide steam or hot water for factories, hotels, and hospitals. In agriculture, they can be used for greenhouse heating and drying agricultural products (such as grains and medicinal herbs).

Power Generation: They can be used as fuel in biomass power plants, either mixed with coal or burned alone to generate electricity, contributing to the transformation of the energy structure.

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.
