Multifunctional Fuel Pellet Production Line in Poland

RICHI MACHINERY

Project Highlights

The 25t/h multifunctional fuel pellet production line in Poland integrates waste sorting, shredding, drying, pelletizing, and emissions control into a unified production system. The facility utilizes modular workshops, allowing flexible allocation of RDF and biomass production lines within existing industrial buildings.

Key features include:

• Dual production system: RDF fuel rods + biomass fuel rods
• High-capacity shredding, crushing, and pelletizing equipment
• Fully enclosed conveying and dust collection systems
• Thermal drying system using natural gas indirect heating
• Integrated environmental protection systems (dust, wastewater, odor control)
• Centralized material handling and automated logistics flow

This configuration ensures that the 25t/h biomass pellet plant can process diverse feedstocks while maintaining stable output quality and compliance with European environmental standards.

Client Background and Investment Motivation

The operational project is established in Poland due to access to stable waste streams and strong demand for alternative fuels in the European energy market.

Poland has been actively transitioning toward renewable energy and alternative fuels, particularly in industrial heating and cement/power generation sectors. The availability of:

• Industrial waste (textile scraps, wood waste)
• Construction and demolition waste
• Municipal solid waste fractions
• Agricultural residues (straw, wood chips, husks)

makes it an ideal location for a multifunctional fuel pellet production line in Poland.

The client’s goal was to build a flexible platform capable of:

• Converting heterogeneous waste into standardized fuel products
• Supplying RDF to power plants and cement kilns
• Producing biomass pellets for boilers and heating systems
• Achieving stable long-term revenue through diversified feedstock sourcing

Production Process Flow

RDF Fuel Rod Production Process

1. Raw Material Receiving & Feeding: Municipal solid waste (MSW) or similar combustible waste is delivered to the plant and unloaded into the receiving area. Materials are then fed into the system via enclosed conveyors or loaders. Initial manual sorting may be applied to remove large impurities or hazardous materials.
2. Primary Shredding: The raw waste is transported via enclosed belt conveyors into a primary shredder. This step reduces large and bulky materials into smaller pieces (typically 100–300 mm) suitable for further processing.
3. Secondary Shredding: The pre-shredded materials are conveyed to a secondary crusher for further size reduction. The output size is typically reduced to 30–80 mm to ensure better uniformity.
4. Screening and Separation: The crushed materials pass through a screening system. Oversized particles are returned to the crusher for reprocessing. At this stage, ferrous metals are removed using magnetic separators, and lightweight/non-combustible fractions may be separated using air classification systems.
5. Drying: The processed materials are transported to a rotary drum dryer through enclosed conveyors. The drying system reduces moisture content to approximately 10%–20%, using hot air generated from a combustion system. This step ensures the material is suitable for densification.
6. Fine Size Reduction: Depending on the material composition, a fine crusher or hammer mill may be used to further refine particle size, improving pelletizing consistency.
7. Pelletizing / Densification: The dried and sized RDF material is fed into a pellet mill or briquetting machine. Under high pressure, the material is compressed into solid fuel pellets without or with minimal binder addition.
8. Cooling: Fresh pellets are discharged at high temperature and are conveyed to a counterflow cooler. This step reduces temperature and stabilizes pellet structure to prevent deformation.
9. Final Screening: The cooled pellets are screened to remove fines and broken particles. Rejected fines are recycled back into the pelletizing system.
10. Storage and Packaging: Qualified RDF pellets are conveyed to storage silos or sent to an automatic packaging system for bagging or bulk loading.

Biomass Fuel Rod Production Process

1. Raw Material Receiving & Storage: Biomass raw materials such as wood chips, sawdust, straw, or agricultural residues are delivered and stored in the raw material yard or bins.
2. Feeding System: Materials are fed into the biomass pellet production line via loaders, screw conveyors, or chain conveyors depending on plant layout.
3. Crushing / Size Reduction: Raw biomass is processed through a hammer mill or wood crusher to achieve a uniform particle size (typically 3–5 mm). This improves pelletizing efficiency and final pellet quality.
4. Drying: If the raw material moisture content is too high, it is sent to a rotary drum dryer. The moisture is reduced to approximately 10%–15% using a hot air system.
5. Material Conditioning: Before pelletizing, materials may pass through a conditioning process where moisture or steam is added. This helps improve material plasticity and activates lignin for better binding.
6. Pelletizing: The conditioned material is fed into a ring die biomass pellet mill. Under high temperature and pressure, the biomass is compressed into cylindrical pellets, relying on natural lignin as a binder.
7. Cooling: The freshly produced pellets are transported to a counterflow cooler to reduce temperature and increase hardness and durability.
8. Screening: Pellets pass through a vibrating screen to separate fines and broken pellets. The separated fines are recycled back into the biomass pellet press.
9. Packaging / Storage: Qualified pellets are stored in silos or packed into bags (e.g., small bags or ton bags) for shipment and sale.
