Biomass Pellet Production Line In Poland

RICHI MACHINERY

overview

This is a biomass pellet production line in Poland project. On November 11, 2022, an investor active in the clean energy market in Eastern Europe contacted us.

This customer is not a large manufacturer, but a project initiator with many years of experience in greenhouse agriculture and small electric heating plants. He hopes to invest in clean energy facilities in Rhodesia and Poland to provide green solutions for greenhouse heating and power plant energy supply.

After the COVID epidemic, he realized that the global energy supply chain is highly vulnerable, so he paid special attention to biomass pellet fuel. With the concept of “self-sufficiency and conforming to green development”, he inquired about two production capacity options of 1.5t/h and 3.5t/h at the same time for flexible decision-making.

After docking with many equipment manufacturers, he chose our company on July 13, 2023 and finalized the “3-4t/h biomass pellet production line in Poland” contract with a total price of 142,660USD, planning to serve green energy projects in northern Poland.

The identity of the customer is very clear: he understands greenhouse and biomass boiler systems and is familiar with local raw material supply. He hopes to achieve a one-stop closed loop of “raw materials-pelleting-fuel” by building his own production line, reducing the cost of purchasing energy and improving energy utilization efficiency.

Raw material structure: diverse choices other than wood

When making pellet fuel, northern Poland has abundant forest waste, but the customer is also engaged in agricultural projects and can provide the following raw material resources:

• Softwood sawdust and shavings: sawdust from forest processing plants with fine particle size;
• Hardwood chips and branches: including shell chips, fallen branches, etc., with relatively high moisture content;
• Corn straw chips: seasonal agricultural waste, which is used for mixing after slicing to increase calorific value;
• Uncarbonized straw or wheat straw: from local agricultural cooperatives;
• Rapeseed straw and peanut shells (a small amount): further increase carbon/energy value;

The mixed use of these raw materials not only provides the market with high calorific value fuel, but also can flexibly utilize the supply in different seasons, significantly reducing production costs. It should also be pointed out that the moisture content of agricultural straw is high, which needs to be precisely controlled during the drying stage.

Process structure: Highly adaptable horizontal layout process

This biomass pellet production line in Poland adopts a typical horizontal layout design, combining the characteristics of wood, agricultural straw, and shell mixed raw materials, optimizing the configuration, and the overall operation is efficient and flexible.

The process flow of this biomass pellet plant in Poland is as follows:

Raw material crushing → hot air drying → MZLH520 granulation → countercurrent cooling → vibration screening → automatic packaging

1. Raw material crushing
   The mixed raw materials enter the three-stage crushing system: first crushed by a drum crusher, and then enter the hammer crusher to refine to a particle size suitable for granulation (≤5mm). This step ensures that raw materials of different materials are mixed evenly and improves the quality of the finished product.
2. Drying treatment
   Use a cyclone hot air dryer to control the moisture content in the range of 8–12%. Agricultural straw has a high moisture content, and intelligent PID temperature control is required to avoid over-drying and dust and reduce granulation resistance.
3. Granulation process
   The core equipment is the MZLH520 ring die biomass pellet mill machine, which can still granulate stably under high humidity and mixed raw materials, and the ring die aperture can be replaced to meet the requirements of different particle specifications. With variable frequency feeding, the output capacity is guaranteed to be 3-4t/h.
4. Cooling stage
   The countercurrent cooler is used to ensure that the temperature of the pellets drops rapidly without cooling and breaking the pellets, thereby improving their hardness and stability.
5. Screening and packaging
   The high-speed vibrating screen removes non-standard particles and dust, and the automatic packaging machine completes the packaging in 25kg bags, which is convenient for transportation and subsequent use.

Revealing the adaptability of multiple raw materials

Although this biomass pellet production line in Poland focuses on biomass pellets, with the MZLH520 and pretreatment system design, it can also flexibly produce:

• Single sawdust pellets: high-end heating;
• Active carbon pellets: pelletizing after carbonization of incineration residues;
• Oil palm shell and fruit shell pellets: improve combustion calorific value;
• Straw and sawdust mixed pellets: create low-cost fuel;
• Organic fertilizer pellets: deviate from the direction of thermal energy and are used for agricultural infrastructure.

This adaptability gives customers a high degree of flexibility in their biomass pellet production line in Poland, allowing them to quickly switch products according to market demand.

Polish market prospects: energy choice behind green energy resolution

In recent years, Poland has accelerated the pace of coal removal and promoted renewable energy, especially in agriculture and greenhouses. The government’s “Clean Energy Subsidy Program” (Czysta Energia Program) provides subsidies for biomass boilers and self-use pellets.

At the same time, in order to reduce carbon emissions and the pressure of increasing energy costs, local greenhouse planting and fruit planting areas are very suitable for self-operated pellet production lines.

Poland is adjacent to the German and Czech markets, and has a strong demand for high-quality pellets, which can be exported to neighboring countries to enjoy higher prices and premium markets. When the customer signed the contract, he hoped to enter the Central European market.

For this reason, we configured the unified ring mold specifications and export packaging standards to enable it to pass the CE certification and relevant EU energy efficiency standards.

It is particularly worth mentioning that there are abundant forests and agricultural waste in rural areas of Poland. The use of pellet processing not only provides fuel, but also reduces the air pollution caused by combustion, which is highly consistent with the government’s environmental protection goals. This project was rated as a “rural green development model” locally and received publicity support from the local council.
