1T/H RDF Pellet Machine for Thermal Energy in India

Feedstock and Raw Materials

The client’s feedstock consists of mixed municipal solid waste and industrial residuals, reflecting Chennai’s urban landscape. Materials include:

• Paper and cardboard from commercial zones
• Plastic packaging such as PET bottles and low-density polyethylene bags
• Wood scraps and non-recyclable biomass residues
• Small quantities of organic waste and textiles

These materials are first pre-shredded into 50–70 mm pieces to ensure smooth feeding into the pelletizer. The client requires pellets with a diameter of 8–12 mm, optimized for consistent combustion in industrial boilers for thermal energy applications. Uniform pellet size ensures efficient energy output, reduces ash accumulation, and facilitates easier storage and handling.

These parameters matched the client’s target output, allowing them to produce sufficient RDF pellets daily while maintaining consistent pellet density and calorific value. The dual-machine configuration also provides flexibility to adjust production schedules based on feedstock availability or operational requirements.

Equipment Functions and Applications

The MZLH420 RDF pellet machine is designed for versatility in processing mixed municipal and industrial waste. Its applications in India include:

• Thermal energy generation for industrial boilers: RDF pellets produced are burned as a reliable, high-energy fuel in nearby manufacturing facilities.
• Urban waste valorization: Converts non-recyclable municipal waste into high-value RDF pellets, reducing landfill volume and promoting sustainable waste management.
• Supplementary fuel for high-temperature industrial processes: Pellets can also serve as auxiliary fuel in cement plants or other thermal energy-intensive industries.

The RDF fuel pellet making machine’s robust rollers, ring die, and forced feeding system allow it to handle variable feedstock densities without bridging or clogging. The uniform pellet size improves combustion efficiency, reduces ash content, and minimizes handling and storage issues. This ensures that energy generation is stable, reliable, and environmentally compliant.

Shipping and Installation

The two RDF pellet machines were shipped via sea freight from Qingdao Port, China, arriving at Chennai Port, India. RICHI Machinery provided full logistical support, including pre-shipment inspection, custom clearance documentation, and technical assistance for offloading.

RICHI engineers were on-site for installation, commissioning, and operator training. Die and roller adjustments were carefully calibrated to achieve 8–12 mm pellet diameters, ensuring the client’s boilers could utilize the RDF pellets efficiently. Operators were trained in daily maintenance routines, troubleshooting, and quality monitoring, enabling smooth startup and immediate productivity. The support ensured minimal downtime and efficient integration with existing waste processing systems.

Technical Advantages and Features

• Versatile feedstock handling: Capable of processing paper, plastics, wood, and biomass simultaneously.
• Adjustable pellet diameter: Ranges from 4 mm to 12 mm, suitable for diverse industrial boilers and thermal energy systems.
• High pellet density and calorific value: Ensures optimal energy output for thermal applications.
• Reliable and durable construction: Heavy-duty rollers and high-quality ring die prevent premature wear and ensure long-term operation.
