0.3–0.5 T/H RDF Pelletizer for Municipal Solid Waste in Malaysia

Feedstock and Raw Materials

The client’s RDF feedstock mainly consists of municipal solid waste, including:

• Household waste such as cardboard, paper, and plastic films
• Small quantities of wood scraps and food packaging residues
• Non-recyclable plastics like PET bottles and low-density polyethylene packaging

To prepare the feedstock for pelletizing, the waste is shredded into particles of 40–60 mm, which ensures smooth feeding into the granulator. The goal is to produce pellets with a diameter of 6–10 mm, suitable for combustion in industrial boilers. Consistency in pellet size is essential for reliable fuel feeding, optimal calorific output, and minimal residue in furnaces.

This capacity was aligned with the client’s current waste processing requirements while leaving room for future expansion. The two-machine setup allows one pelletizer to continue production while the other undergoes preventive maintenance or troubleshooting, ensuring uninterrupted operations and consistent fuel output.

Equipment Functions and Applications

The MZLH350 RDF pelletizer in Malaysia is engineered to handle a wide range of municipal waste, producing dense, uniform pellets. Its main applications in Malaysia include:

• Industrial boiler fuel: The pellets provide stable combustion and consistent heat output for factories and energy plants.
• Waste-to-energy transformation: The granulator converts non-recyclable municipal waste into high-value fuel, reducing landfill volume.
• Supplementary energy for high-temperature industrial processes: Pellets can serve as auxiliary fuel in cement kilns or other high-temperature operations.

The machine’s reinforced rollers and ring die system guarantee uniform compression, while the forced feeding mechanism prevents bridging, even with heterogeneous feedstock. Its operation produces pellets with high calorific value and minimal dust emissions, ensuring safe and efficient handling. The design also reduces maintenance requirements and allows operators to easily monitor pellet quality and production performance.

Shipping and Installation

The two RDF pelletizers were shipped from Qingdao Port, China, to Port Klang, Malaysia, via sea freight. RICHI Machinery provided full logistical support, including:

• Pre-shipment inspection and quality verification
• Detailed documentation for customs clearance
• Technical guidance for offloading, placement, and assembly

Upon delivery, RICHI engineers assisted with installation, calibration, and commissioning. Special attention was given to adjusting die settings to produce the target 6–10 mm pellet diameter, ensuring compatibility with the client’s industrial boilers. The engineers also trained operators on daily maintenance, troubleshooting, and pellet quality control, ensuring immediate operational efficiency. This comprehensive installation and training support maximized plant uptime and operational safety.

Technical Advantages and Features

• Versatility: Capable of processing mixed-density municipal waste, including plastics, paper, and small wood fragments.
• Adjustable pellet size: Pellets can range from 4 mm to 12 mm in diameter, catering to multiple industrial applications.
• Stable operation: Heavy-duty construction, precision rollers, and high-quality dies ensure long-term reliability.
• High pellet density: Dense pellets enhance calorific value and reduce fuel consumption.
• Energy-efficient design: Optimized mechanical layout minimizes electricity usage while maintaining throughput.
• Operator-friendly control: Feeding rate, die selection, and pellet size can be easily adjusted for consistent results.
• Low-maintenance operation: Easy access to dies and rollers allows quick replacement and preventive maintenance.
• Environmental compliance: Minimal dust emissions and consistent pellet quality help meet local environmental regulations.

The client selected RICHI RDF pelletizer due to its proven reliability in RDF processing, robust construction, and strong after-sales support, which together mitigate operational risks and support long-term operational efficiency.

Client Feedback

After four months of operation, the client provided the following feedback:

“RICHI’s RDF pelletizers have transformed our municipal solid waste processing. We are now producing consistent pellets daily, and our industrial boilers run more efficiently than ever. The machines handle mixed waste effortlessly, and the technical support from RICHI made installation and training seamless.
