Project Overview
-
Date: April 10, 2026
-
Location: Guoxin Group Manufacturing Workshop
-
Material: Mixed Plastic Film & Combustible Packaging Waste
-
Process: Two-Stage Shredding + RDF High-Pressure Forming
-
Objective: To verify the density and calorific consistency of RDF fuel rods produced from low-density film waste.
Primary shredding of plastic film for RDF production
Fine shredded plastic waste <30mm for fuel pellets
High-density RDF fuel rods from plastic film waste
The Process: From Loose Film to Solid Energy
Phase 1: Primary Shredding (Volume Reduction)
Plastic films are notorious for being “light and bulky,” making them difficult to feed directly into forming machines. Our Primary Shredder first reduces the large rolls and loose films into uniform strips.
-
Key Tech: High-torque, low-speed shearing to prevent the film from melting or wrapping around the blades.
Phase 2: Secondary Fine Shredding (Size Control)
To achieve high-density RDF, the material size must be strictly controlled. The primary shredded film passes through our Secondary Fine Shredder, reducing the particle size to <30mm.
-
Why this matters: Consistent particle size ensures even feeding into the RDF forming machine, preventing air pockets within the final fuel rod.
Phase 3: High-Pressure RDF Forming
The finely shredded material is then conveyed into the RDF Forming Machine. Under high pressure (without any chemical binders), the plastic fibers are compressed into high-density fuel rods.
-
Result: The final RDF rods exhibit high mechanical strength and are optimized for long-distance transport and stable combustion in industrial boilers.
Trial Results & Technical Highlights
-
Density Increase: The loose film was transformed into solid fuel, resulting in a significant density increase, making it an ideal coal substitute.
-
Stable Operation: The PLC-integrated control system ensured a smooth transition between the secondary shredder and the forming unit, even with fluctuating feeding speeds.
-
Customization: This trial run proved that our [RDF Shredding Solution] can be adjusted to meet specific diameter requirements for different burner systems.
