Project Layout For Customer:

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

Equipment for processing wet wood biomass pellets (i.e., pellet forming equipment for high-moisture wood feedstock) must address the molding difficulties caused by excessive moisture content. Its principles and characteristics differ significantly from those used for processing dry wood. The key to processing wet wood biomass pellets (typically with a moisture content exceeding 30%, and even reaching 50%-60%) is the synergistic effect of drying and mechanical compression to overcome the molding barrier caused by high moisture content, ultimately producing dense pellets.

2. Characteristics of wet wood log biomass pellet processing equipment

(1) Strengthen pretreatment capacity to adapt to high-moisture raw materials

Equipped with high-efficiency crushing equipment (such as knife crushers and hammer crushers), wet wood (including branches, bark, wet sawdust, etc.) can be crushed into uniform fine particles to prevent large pieces of material from clogging the molding machine.

Use a drum dryer to directly reduce moisture in the pretreatment stage and reduce the subsequent molding pressure.

(2) Special design of the molding mechanism to improve anti-adhesion and wear resistance

The mold and pressure wheel are made of wear-resistant materials (such as high-chromium cast iron, carburized alloy steel), and the surface finish is improved to reduce the "sticking mold" phenomenon caused by the high viscosity of wet materials and extend the life of wearing parts.

The mold aperture is usually large (8-12mm) and the compression ratio (the ratio of mold length to aperture) is low (generally 3-5:1), which reduces the flow resistance of wet materials in the mold and avoids clogging. Some equipment uses "variable diameter molds" with a large aperture at the inlet and a small aperture at the outlet, gradually increasing the pressure to adapt to the plasticity characteristics of wet materials.

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

(1)Civilian Use: 

It can be used for home heating and cooking (through devices like pellet fireplaces and pellet stoves). It's simple and clean to operate, replacing traditional coal and firewood to improve the indoor environment.

(2)Industrial Use: 

It can be used as a boiler fuel to provide steam or hot water for factories, hotels, hospitals, and more. In agriculture, it can be used for greenhouse heating and drying agricultural products (such as grains and medicinal herbs).

(3)Power Generation:

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

TONY Brand 3.5-4Ton/Hour Wet Wood Log Pellet Manufacturing Plant can take wet wood, 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.

Project Market Analysis 

1. Market Demand 

(1) Industrial sector:

With the increasingly stringent environmental protection policies, many industrial enterprises (such as food factories, chemical plants, textile factories, etc.) are restricted in the use of traditional high-pollution fuels (such as coal), and are in urgent need of finding clean and efficient alternative energy sources. Wood pellets, as an ideal biomass fuel, have similar combustion characteristics to coal, but significantly reduce pollutant emissions, can meet the heating needs of industrial boilers, and have relatively low operating costs. Therefore, the market demand in the industrial sector continues to grow. 

(2) Civilian sector:

In terms of winter heating and rural living energy consumption, wood pellets are gradually gaining favor among consumers due to their environmental protection and economic characteristics. Compared with traditional coal heating, using wood pellets for heating can not only reduce indoor air pollution and improve the living environment, but also effectively reduce heating costs. In addition, with the continuous improvement of people's environmental awareness, the pursuit of a green and healthy lifestyle has also led to a continuous increase in the demand for wood pellets in the civil market. 

(3) Biomass power generation sector:

As an important renewable energy power generation method, biomass power generation has developed rapidly with the support of national policies. As a high-quality fuel for biomass power generation, wood pellets offer stable calorific value and high combustion efficiency. This improves power generation efficiency, reduces costs, and provides a reliable fuel source for biomass power generation companies. Consequently, demand for wood pellets in the biomass power generation sector has been increasing year by year.

2. Market Supply

Currently, the wood pellet market primarily comes from small and medium-sized processing companies and individual operators. While there are a large number of manufacturers in the market, their overall scale is relatively small, their production equipment and technical levels vary, and product quality varies significantly. Limited production scales hinder some companies from meeting large-scale market demand. Meanwhile, some companies employ outdated production processes, resulting in pellets with low calorific value and high ash content, failing to meet the demands of the high-end market. Therefore, while overall production capacity can meet certain market demands, the supply of high-quality, stable products is relatively insufficient, creating market opportunities for new entrants.

Wood pellets are solid fuels or industrial raw materials made from wood processing waste (such as sawdust, wood chips, scraps, etc.) through crushing, drying, compression molding and other processes. The following are the physical properties of wood pellets.

 (1) Regular shape and high density. 

Usually cylindrical particles with a diameter of 6-12mm and a length of 20-50mm. The structure is dense and the bulk density can reach 600-800kg/m³ (much higher than the 100-200kg/m³ of raw wood chips), which greatly reduces storage and transportation space and reduces logistics costs. High hardness (crushing strength is generally >80%), not easy to break, easy to mechanized handling and automatic feeding (such as automatic feeding systems for boilers and fireplaces).

(2) Controllable moisture and strong stability. 

The moisture content of the finished pellets is usually controlled at 8%-15% (adjusted according to the purpose). The moisture content is low and uniform, avoiding the problem of mold and rot caused by moisture in the raw wood chips. The storage period can be extended to 6-12 months (under sealed conditions).

Wood pellets have become an important alternative to fossil energy due to their clean, efficient and renewable characteristics. They have been widely used in areas with strict environmental protection requirements (such as Europe and North America).
