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

(1)Pre-treatment: "Homogenization" of wet wood chips

Wet wood chips (such as wood processing waste, construction waste wood chips, etc.) usually have problems of uneven size and humidity fluctuations. They need to be adjusted to a state suitable for molding through pre-treatment to avoid subsequent blockage or molding failure.

(2)Core molding: "Fiber reorganization and densification" under mechanical extrusion

This is the key step in converting wet wood chips into pellets. The core principle is "high-pressure extrusion + wood fiber self-bonding" - the lignin in the wet wood chips (a natural adhesive that softens under pressure and frictional heat) works together with water to make the fibers tightly bonded to form pellets of fixed shape.

(3)Cutting and shaping: "Precise control" of pellet length

The wet wood chips squeezed out of the mold forming hole will form "continuous cylindrical strips" that need to be cut into pellets of uniform length by a cutting mechanism. 

(4)Cooling and screening: the final checkpoint for pellet quality

(5)Auxiliary systems: ensuring stable operation of the equipment

Wet wood chip pellet processing equipment requires auxiliary systems to solve problems such as "blockage and overload" during wet material processing. The core systems include electronic control systems, dust removal systems, and lubrication systems.

2.Characteristics of wet wood chips biomass pellet processing equipment

(1)High efficiency and energy saving: For example, pellet machines have low energy consumption, high output, compact process, small footprint, good dust removal effect, low noise, and a good production environment. A production line only requires 2-3 workers and can be operated automatically, reducing labor costs.

(2)Low maintenance cost and easy operation: Wood pellet machines have low maintenance costs and do not require grease injection. Non-professionals do not need much time to complete maintenance. The wearing parts are practical and durable. The roller bearings are made of international brands and are not easy to damage. They are easy to operate and do not require professional operation. 

(3)Raw material processing and environmental protection are taken into consideration: The moisture content of the raw materials before pellet processing needs to be controlled at about 10-15%. Therefore, drying equipment may be required in actual production. Wood pellets contain few harmful substances and the content of harmful gas components during combustion is extremely low. The ash after combustion can be used as potash fertilizer, which meets environmental protection requirements.

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

(1)Biomass energy field

As a clean fuel: The processed wood pellets have high calorific value and high combustion efficiency, and their sulfur, ash and nitrogen content are much lower than fossil fuels such as coal and oil. They can be directly used for fireplaces and boiler heating, or as fuel for biomass power plants, achieving energy substitution and emission reduction goals.

Energy conversion advantages: Compared with traditional fuels, wood pellets are smokeless and odorless when burned, with low pollutant emissions, which meets the needs of modern green energy, especially in Europe and America where the demand for biomass energy is relatively high.

(2)Animal feed field

Feed pellet production: Wood pellets processed by wood pellet machines can be used as high-quality feed for poultry and livestock breeding, improving feed utilization and animal production efficiency. Some equipment is specially designed for feed pellets to meet the process requirements of feed processing.

(3)Environmental protection and resource recycling field

Wood waste processing: The equipment uses wood chips, sawdust, branches and other wood processing waste as raw materials, converting waste that might have been discarded into high-value pellet products, realizing resource recycling and reducing environmental pollution.

TONY Brand 28-35Ton/Hour Wet Wood Chips Pellet Manufacturing Plant can take wet wood chips, various types of wood - related biomass materials, such as wood pallets ,branches, wood logs, and wood shavings.

1.Project Core Objectives

The wet wood chip pellet project aims to achieve efficient resource utilization through technological transformation. Its core objective is to convert wet wood chips into high-calorific-value, easily storable biomass pellet fuel, meeting the clean energy needs of industrial boilers and residential heating applications.

2.Market-Driven Logic

With tightening environmental protection policies and growing demand for renewable energy, market demand for biomass pellets, a key alternative to fossil fuels, continues to expand. The project aims to enhance its competitiveness by increasing product density and reducing moisture content (typically ≤15%). Furthermore, the project will optimize its site selection based on regional forestry resource distribution, locating close to raw material production areas to reduce transportation costs.

Biomass pellets processed from wood chips offer low cost, increased density, high energy efficiency, and a wide range of applications.

Biomass pellets processed from wood chips offer low cost, high added value, and a significantly lower cost than petroleum-based energy. They are a nationally advocated clean energy alternative with a broad market potential. The pelletized fuel is compact, has a high specific gravity, and high density, making it easy to process, convert, store, transport, and reuse. They have a high calorific value: 2.5-3 kg of wood pellets have the same calorific value as 1 kg of diesel, but at less than half the cost, and boast a burnout rate exceeding 98%. These pellets are widely used in industrial and agricultural production, power generation, heating, boiler burning, cooking, and are suitable for both households and businesses.
