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

Wet wood pellet processing equipment is key to converting wet wood chips into uniform, dry, and storable wood pellets. Its operating principle generally includes four core stages: crushing, drying, compression molding, and cooling. The entire process is designed to increase the density of the raw material, reduce its moisture content, and enhance its performance as a biomass fuel or other applications.

2.Characteristics of wet wood chips biomass pellet processing equipment

(1)Strong adaptability to raw materials: It can process a variety of wet wood chips and biomass raw materials, including wood processing waste such as eucalyptus, birch, and poplar, as well as crop straw, bamboo chips, etc. Through pre-treatment steps such as crushing, drying, and screening, wet wood chips are converted into raw materials that meet the requirements of pelletizing. 

(2)Integrated processing flow: The equipment is usually equipped with integrated production lines such as crushing, drying, pelletizing, cooling, and packaging to ensure the continuous processing of wet wood chips from raw materials to finished pellets. 

(3)Key technologies in the drying process: Some equipment integrates drying functions to quickly reduce the moisture content of wet wood chips to meet the moisture content requirements of raw materials before pelletizing.

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 80-100Ton/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 the following advantages:

1.Renewable Energy:

Biomass pellets are derived from waste wood and agricultural residues, resulting in minimal environmental impact and a renewable energy source.

2.Low CO2 Emissions:

Compared to fossil fuels, the combustion of biomass pellets produces lower CO2 emissions, contributing to global climate change mitigation.

3.High Calorific Value:

Pine wood pellets have a calorific value of 4200-5000 kcal/kg, making them one of the highest calorific biomass fuels.

4.Low Ash Content:

Pine wood pellets have a low ash content, typically 1-3. Compared to coal, this ash content leaves very little ash and residual ash. This low ash content significantly increases the fuel's utilization rate, saving fuel.

5.Environmental Advantages:

The main components of the combustible gases released after pyrolysis of pine wood pellets are H2, CH4, CmHn, and CO. Emissions of SO2, CO, and NO after full combustion are negligible. Therefore, pine wood pellets offer significant environmental advantages compared to coal. 

6.Economical:

The utilization rate and unit price of pine wood pellet fuel are high. Compared with fuel oil, gas, electricity and other energy sources, pine wood pellet fuel is a relatively cost-effective energy source. It can generally save 50% compared with fuel oil and gas, and 80% compared with electricity. It is 10% cheaper than anthracite and about 20-30% more expensive than low-quality polluting coal.
