This is a project about an RDF granulator for wood and plastic waste in South Korea. The client operates a medium-sized commercial RDF plant that transforms industrial and municipal solid waste into uniform, high-density pellets suitable for industrial boiler fuel.
RICHI Machinery recently delivered a set of RDF granulators for wood and plastic waste in South Korea to a private waste-to-energy facility located near Incheon. The client operates a medium-sized commercial RDF plant that transforms industrial and municipal solid waste into uniform, high-density pellets suitable for industrial boiler fuel. With South Korea’s strict environmental regulations and increasing focus on renewable energy, the client identified a strong need for a reliable solution to convert heterogeneous waste streams into consistent fuel pellets.
Previously, the client relied on manual shredding combined with small-scale compression systems. This setup caused frequent operational downtime, inconsistent pellet size, and low calorific value in the final product. To upgrade their process, the client opted for two standalone MZLH420 RDF granulators, forming the initial stage of a larger planned RDF production line. These machines were chosen specifically for their adaptability to mixed wood and plastic waste, providing a flexible, high-quality solution without requiring an entire line investment upfront.
Purchasing these machines as standalone units allowed the client to test and optimize the RDF pellet process with current feedstocks before committing to a full-scale automated production line. This decision also reduced initial capital expenditure while enabling rapid installation and operation. The project reflects the client’s strategic focus on operational efficiency, sustainability, and regulatory compliance, while preparing for future expansion of their RDF capabilities.
Name:
RDF granulator
Country:
South Korea
Date:
2025
Capacity:
1T/H
Model:
MZLH420
Main Motor Power:
90 kW
Raw Materials:
wood offcuts, plastics
Pellet diameter:
6–10 mm
The client’s RDF feedstock primarily consists of industrial wood offcuts, laminated wood panels, shredded plastics, and packaging films sourced from local manufacturers and recycling centers. Key components include:
Before processing, the materials are manually sorted and shredded into particles approximately 30–50 mm in size to ensure smooth feeding into the RDF granulators. The client’s goal is to produce pellets of 6–10 mm in diameter, optimized for industrial boiler combustion. Uniform pellet size is critical to maintain a stable burning rate, prevent clogging, and improve energy efficiency, while also reducing dust and minimizing wear on downstream equipment.
| Main Motor | Arch Breaker Feeder | Forced Feeder | Ring Die Diameter | Pellet Diameter | Production Capacity |
|---|---|---|---|---|---|
| 90 kW | 3 kW | 1.5 kW | 420 mm | 6–10 mm | 1.0–1.2 T/H per machine |
The dual-machine setup ensures continuous operation, with one unit able to run while the other undergoes routine maintenance or troubleshooting. This arrangement also allows gradual optimization of the production process, testing different feedstock ratios and operational parameters to achieve the highest quality RDF pellets.
The MZLH420 RDF granulator is specifically designed to handle heterogeneous wood and plastic waste while producing uniform, dense pellets. Its main applications in South Korea include:
The machine’s design allows for consistent pellet density, reduced dust emissions, and minimal operational interruptions. Its heavy-duty rollers and ring die system ensure uniform compression, while the forced feeding mechanism prevents bridging and blockages, even with mixed feedstocks. The equipment also contributes to safer handling of combustible materials, reducing the risk of fires or operational hazards.
The RDF granulators were shipped from Qingdao Port, China, via sea freight to Busan Port, South Korea, the primary commercial shipping hub for industrial equipment imports. RICHI Machinery provided complete logistical support, including:
Upon arrival, RICHI engineers supervised the setup, ensuring that the machines were correctly aligned, the dies and rollers calibrated, and operators trained in daily maintenance, safety protocols, and pellet quality control. The commissioning process also included adjusting die sizes to produce the target pellet diameter of 6–10 mm, ensuring optimal fuel performance in the client’s boilers. The professional installation support also ensured that the plant met local safety and environmental compliance standards.
The client chose RICHI fuel pellet machine due to its proven track record with RDF applications, robust construction, and comprehensive technical support, which reduces operational risk for commercial facilities in South Korea. Additional benefits include lower energy costs, enhanced operational safety, and reduced environmental impact.
After three months of continuous operation, the client provided feedback:
“The RDF granulators from RICHI exceeded our expectations. They handle mixed wood and plastic waste without clogging, and the pellet quality is consistent every day. We can now run our industrial boilers at full capacity without interruptions. RICHI’s team provided excellent installation support and practical training for our staff, which made the transition smooth. The dual-machine setup ensures one machine can operate while we maintain the other, which keeps our production steady.”
The client highlighted that the consistent pellet diameter and density directly improved boiler efficiency, reduced maintenance costs, and enabled better energy planning, confirming the machine’s commercial value for medium-scale RDF operations.
The RDF granulator for wood and plastic waste in South Korea project demonstrates RICHI Machinery’s commitment to delivering versatile, durable, and high-performing RDF solutions for commercial energy facilities. The client achieved several benefits:
RICHI’s RDF granulators provide a cost-effective, energy-efficient solution for commercial clients aiming to transform waste into a valuable energy resource.
With professional installation, operator training, and ongoing support, clients can trust RICHI Machinery to maximize productivity, reliability, and fuel quality for a wide range of RDF applications. This project exemplifies RICHI’s dedication to sustainable energy solutions, operational efficiency, and customer satisfaction in diverse industrial contexts.
