1. The working principle of wet sawdust biomass pellet processing equipment

The overall principle of wet sawdust pellet processing equipment is to transform irregular, high-impurity, and high-moisture wet sawdust into regular, impurity-free, high-density, and easily storable biomass pellets through a continuous physical process of drying and conditioning, high-temperature and high-pressure molding, and cooling and stabilization. The entire process is chemical-free, relying on the inherent adhesive properties of the wood fibers to achieve molding. This not only solves the environmentally friendly disposal issue of wooden pallet waste but also enables resource recycling (the pellets can be used as fuel, feed carrier, and more).

2. Characteristics of wet sawdust biomass pellet processing equipment

(1) High efficiency and energy saving: The wet sawdust pellet machine can process waste materials such as wood chips into pellet fuel, which not only reduces environmental pollution but also realizes the recycling of resources and greatly improves energy utilization efficiency.

(2) Multifunctionality: In addition to being able to process biomass fuel, the wet sawdust pellet machine can also process animal feed, organic fertilizer, etc., and is widely used in agriculture, breeding and other fields. 

(3) Advanced pelletizing technology: The wet sawdust pellet machine adopts advanced pelletizing technology, which can automatically control parameters such as feed amount and temperature during the pelletizing process, greatly reducing production costs and making the production process more economical and environmentally friendly.

(4) High-quality components: The main shaft and the connected hollow shaft of the wet sawdust pellet machine are made of alloy structural steel imported from Germany through water forging, rough turning, heat treatment, fine turning and fine grinding. The reasonable structure and uniform hardness improve the fatigue resistance and wear resistance of the components, providing more reliable guarantee for safe operation.

3. Application scenarios of wet sawdust biomass pellet processing equipment

Wood pellets (also known as "biomass pellet fuel") have become a valuable alternative to traditional fossil fuels such as coal and heavy oil due to their high combustion efficiency, low pollution emissions, and convenient storage and transportation. Wood pellets are also a popular application for 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 (which have a calorific value of approximately 4200-4800 kcal/kg, similar to medium-quality coal).

(2) Residential Heating/Household Energy:

Wood pellets can be used as fuel in domestic biomass heating stoves and fireplaces. Pellets burn stably (with no black smoke or odor) and are automatically fed through a dedicated hopper, eliminating the need for frequent refilling. Furthermore, some catering businesses, such as small restaurants, use wood pallet pellets instead of liquefied petroleum gas for heating, reducing energy costs. 3. Supplemental Fuel for Power Plants:

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

Three Fundamental Supports for the Feasibility of Processing Wet Sawdust into Biomass Pellets

The success of this project depends on the maturity of three key factors: raw material supply, policy guidance, and market demand. These factors are also the core focus of preliminary research.

1. Raw Material Supply: A stable and low-cost supply of raw materials is a prerequisite.

The source, supply volume, and cost of wet sawdust directly determine the project's profitability and require rigorous evaluation:

Raw Material Source Scenario:

Core Channels: Wood processing plants, furniture factories, board mills, etc.

Supply Characteristics: Sawdust from these sources can be produced in large quantities and is often recycled for free or at a low price, resulting in extremely low raw material costs.

Suitability of Raw Material Processing:

Wood dust (especially solid wood sawdust and Scots pine) has a high fiber density, and the resulting pellets can reach a calorific value of 4200-4800 kcal/kg (comparable to medium-quality coal), far exceeding agricultural waste such as straw and rice husks. Since it requires no complex pre-treatment (such as nails and clamps) and produces minimal oil pollution, it is well-suited for processing.

2. Policy Direction: Dual Benefits of Environmental and Energy Policies

Biomass pellets are a compliant alternative fuel with low market entry barriers. This project falls under the "Solid Waste Resource Utilization" category, meeting the "reduction and resource utilization" requirements.

3. Market Demand: Strong Industrial and Residential Market Demand

The market demand for biomass pellet fuel is stable, with no need to worry about stock shortages:

Industrial (Core Customers): Small and medium-sized boilers (1-10 tons) in food processing, textile, and building materials factories, ceramic kilns, and biomass power plants (for co-firing).

Residential (Supplementary Customers): Home heating stoves, cooking energy in southern farmhouses and small restaurants, and home fireplace users.

Sawdust pellets, used as biomass pellet fuel or industrial auxiliary material, possess stable physical and chemical properties, offering a user experience far superior to traditional loose wood and coal. Specifically, sawdust pellets have the following characteristics:

1. High energy density and high combustion efficiency

After compacting, sawdust reaches a density of 1.1-1.3 g/cm³ (much higher than the 0.4-0.6 g/cm³ of loose wood), reducing its volume by 6-8 times and generating a calorific value per unit volume of 4200-4800 kcal/kg (comparable to medium-quality coal). Sawdust pellets are also less prone to slagging during combustion. Sawdust pellets boast a thermal efficiency over 30% higher than loose wood, making them suitable for use in equipment such as boilers, fireplaces, and hot air furnaces.

2. Convenient storage and transportation, low cost

The pellets are uniformly shaped (mostly cylindrical, 6-10 mm in diameter and 10-30 mm in length) and have good flowability. They can be transported in bags, silos, or conveyor belts, and are moisture-resistant and deformation-resistant. They require only one-fifth the storage space of bulk wood of equivalent thermal mass, and there's no concern for insect infestation or mold (the high temperatures during the pelletizing process kill insect eggs and mold), reducing labor and space costs during storage and transportation.

3. Fewer entry points, wide adaptability

Sawdust pellets can be used directly in automated biomass combustion equipment (such as pellet stoves and biomass boilers). No complex pre-processing (such as chopping or pulverizing) is required; they simply need to be fed at a constant rate through a feeder. Their simple operation makes them suitable for applications such as industrial heating, home heating, and agricultural greenhouse insulation. They can also serve as an auxiliary fuel in biomass power plants.
