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

The core equipment in pallet pellet processing is the biomass ring die pelletizer, which utilizes a combination of mechanical extrusion, frictional heating, and fiber self-bonding. The specific process is as follows:

During the extrusion process, rollers exert a pressure of up to 50-150 MPa on the powder, forcing it from its loose state (density 0.15-0.3 g/cm³) into the die's forming hole, forming a cylindrical column.

As the powder moves through the hole, it creates intense friction with the hole walls. Frictional heating raises the column temperature to 100-120°C, completely melting the softened lignin and hemicellulose, forming a natural adhesive that tightly binds the surrounding wood fiber particles together.

At the same time, the high temperature and pressure also remove some free moisture from the material (reducing the final pellet moisture content to 10%-15%) and rearranges the wood fiber structure, forming a high-density, high-strength column (density increased to 0.8-1.2 g/cm³).

2. Characteristics of dried wood pallets biomass pellet processing equipment

The wood pallet pellet processing equipment is a complete set of processing equipment designed specifically for waste wood pallets (including complex raw materials such as metal nails, plywood, and wood with different moisture contents). Its characteristics revolve around four core requirements: raw material adaptability, process adaptability, performance stability, and environmental compliance. It not only solves the "pain points" of wood pallet recycling (such as impurity removal and uneven material quality), but also ensures the efficiency and quality of pellet production.

(1) Strong adaptability to raw materials: Targeted solution to the "difficulties" of wood pallet processing

(2) High process integration: Achieve One-Stop Continuous Production

(3) Durable Core Components: Suitable for high-load, high-wear scenarios.

(4) Environmental and Safety Considerations: Compliance with Industrial Production Standards. 

(5) High Flexibility: Adaptable to diverse needs.

3. Application scenarios of dried wood pallets biomass pellet processing equipment

Wood pallet pellet processing equipment is the core equipment for realizing the transformation of “waste wood pallets → biomass pellets”. Its application scenarios are centered around the source of raw materials, production scale, and processing needs. It is mainly divided into two categories: “centralized processing projects” and “supporting processing scenarios”: 

(1)Centralized processing projects: large-scale production scenarios This type of scenario takes “large-scale processing of waste wood pallets and batch production of biomass pellets” as its core goal. The equipment must have high production capacity and a high degree of automation. It is usually implemented as an independent biomass pellet processing plant: Professional biomass pellet plant: Build a large-scale processing plant in an area with developed logistics and abundant waste wood pallet resources, and configure a complete production line of “wood pallet dismantling machine → crusher → dryer → pelletizer → cooling and screening machine → packaging machine” with a daily production capacity of 50-200 tons. The products are mainly supplied to B-end customers such as industrial boilers and power stations;

(2)Supporting processing lines for solid waste treatment centers: Large-scale industrial solid waste treatment centers (such as centers for processing waste wood and waste packaging in the manufacturing industry) add wood pallet pellet processing equipment to convert waste wood pallets that originally needed to be landfilled/incinerated into high-value-added pellets, realizing "Solid waste reduction (over 80% reduction) + resource utilization" while also receiving environmental protection subsidies (such as solid waste treatment subsidies and pellet sales subsidies).

(3)Supporting processing scenarios: on-demand processing and local utilization.This type of scenario aims to "reduce the cost of raw material transportation and meet the energy needs of itself/surrounding areas". The equipment scale is flexible (small/medium-sized) and is usually directly matched with the producers and users of wood pallets:

(4)Logistics parks/manufacturing factories self-processing: Large logistics parks and production enterprises (such as auto parts factories and furniture factories) generate a large number of waste wood pallets every year. They build supporting "small processing workshops" to process the processed pellets directly for their own factory heating and production heat, without the need to purchase energy from outside, thus reducing energy costs (saving 20%-30% compared to purchasing natural gas/coal);

(5)Biomass boiler user supporting processing: Enterprises using biomass boilers (such as textile factories and chemical plants) build supporting processing lines within the factory area to process the recycled waste wood pallets into pellets and directly supply them to their own boilers, avoiding quality fluctuations (such as excessive ash content and insufficient calorific value) and transportation costs of purchased pellets, thus realizing the internal cycle of "raw materials - production - energy use";

(6)Rural/ Small-scale processing sites in townships: In townships with developed agriculture and scattered waste wood pallet resources, small-scale processing sites are built, equipped with simple production lines (such as "mobile crusher + small pelletizer"). Products are mainly supplied to surrounding farmers for heating and small-scale agricultural drying (such as greenhouse heating and grain drying), meeting regional scattered needs and reducing farmers' energy costs.

How to deal with the profit fluctuations of the pallet pellet project? The sustainability of the project requires both "increasing revenue" and "reducing costs", while establishing a risk buffer mechanism: 

1. Refining cost control to improve gross profit margin

(1)Control "variable costs": Raw materials (accounting for 50%-60%) are locked in price through long-term agreements; energy consumption (electricity and heat, accounting for 15%-20%) is reduced through waste heat recovery and equipment frequency conversion transformation; labor (accounting for 10%-15%) is reduced through automated equipment (such as automatic feeders and pellet packaging machines). 

(2)Optimize "fixed costs": Equipment depreciation (depreciation based on 5-8 years) is diluted by improving capacity utilization; factory rent can be negotiated with the industrial park for "long-term low-price lease" (e.g., for a lease term of more than 5 years, the annual rent increase does not exceed 5%). 

2. Develop a risk contingency plan to deal with emergencies

(1)Raw material supply disruption: Reserve 1-2 months of raw materials and sign emergency agreements with 2-3 "backup suppliers" (such as wood pallet recycling companies in surrounding cities) to ensure that raw materials are replenished within 72 hours.

(2)Response to market price drops: If the price of pellets drops due to competition or policy fluctuations, maintain gross profit margin and avoid losses by "reducing costs" (such as adjusting the raw material formula and increasing the proportion of low-priced straw) or "improving efficiency" (increasing production capacity and diluting unit costs).

1. Stable performance: strong adaptability and easy operation.

The physical properties and combustion performance of pallet pellet fuel are superior to those of traditional biomass fuel (such as loose straw and logs), and it is easier to meet the needs of industrial and civilian scenarios: 

(1) High energy density and easy storage and transportation:

After compression molding, the volume of pellet fuel is only 1/5~1/3 of the raw material (loose pallet fragments), the density can reach 1.1~1.3t/m³, and the energy density is about 4200~4800kcal/kg (close to medium-quality coal); and the particle shape is regular and not easy to absorb moisture, so it can be stored in ordinary warehouses. There is no scattering or dust during transportation, and the logistics cost is more than 30% lower than that of loose biomass. 

(2) Stable combustion and precise temperature control:

When pellet fuel burns, the flame is uniform and the heat release is stable. It will not flicker like loose straw. It is suitable for scenarios that require a stable heat source (such as industrial boilers, drying equipment, and home heating stoves). When paired with a dedicated pellet burner, it can achieve automatic feeding and temperature control, and the operation difficulty is lower than that of traditional fuels.

2. Economic advantage: cost control

(1) Low raw material cost:

Waste pallets belong to the category of "waste recycling" and the purchase price is much lower than that of raw materials such as logs and corn stalks, which directly reduces the production cost of pellet fuel.

(2) The use cost is lower than fossil energy:

From the perspective of terminal use cost, the unit heat cost of pallet pellet fuel is about 1.2 to 1.5 times that of coal, but much lower than natural gas (about 1/2 to 2/3 of natural gas) and liquefied gas (about 1/3 to 1/2 of liquefied gas). For industrial heat use (such as food processing, building material drying), commercial heating and other scenarios, long-term use can significantly reduce energy expenditure.
