Products Description
Guoxin RS-1500 Shredder processes mixed plastics into 50mm RDF fuel rods.
RDF (Refuse-Derived Fuel) production requires a stable, uniform, high-calorific fuel to ensure reliable downstream use in cement kilns, power plants, and industrial boilers.
An RDF shredder solution is a core subsystem designed to process combustible waste into consistent RDF fuel with controlled particle size.
This page explains how RDF shredders work, how to select the right configuration, and what factors affect investment costs, providing you with a complete and reliable RDF shredding solution.
Double-Shaft Shredder
What Is an RDF Shredder?
An RDF shredder is a heavy-duty waste shredding system designed to process high-calorific waste into uniform fuel. Depending on the material toughness and required output size, we offer two primary drive systems:
- Double-Shaft Shredder: Best for primary shredding of bulky mixed waste. High torque, low speed, and excellent for breaking down tough materials.
- Single-Shaft Fine Shredder: Ideal for secondary shredding to reach final output sizes (<50mm). Features a pusher system for consistent feeding and high-precision cutting.
It is typically installed after MSW or construction waste sorting, or after MBT systems, to produce uniform RDF suitable for energy recovery.
Our industrial RDF shredding machines feature high-torque double-shaft or single-shaft designs with hardened alloy blades, ensuring stable processing of tough materials like plastics and textiles
In many waste-to-energy projects, RDF shredders are integrated with a complete RDF production line to produce alternative fuel for cement plants.
RDF Shredder in the RDF Production Line
In a standard RDF production line, the shredder plays a critical role:
• Receives pre-sorted combustible fractions
• Reduces material size to the RDF specification
• Improves fuel homogeneity
• Enhances calorific value consistency
• Ensures stable downstream combustion or co-processing
Typical RDF output size: 30–80 mm, depending on end-user requirements.
An RDF shredder is not an isolated machine, but a key processing unit within a complete RDF production line. Its primary function is to reduce combustible waste to a controlled particle size suitable for downstream screening, separation, and RDF forming processes.
In practical projects, RDF shredders must be selected based on waste composition, moisture content, required RDF output size, and overall plant capacity to ensure stable fuel quality and long-term system reliability.
RDF Shredder Capacity and Typical Throughput
RDF shredders used in waste-to-energy and cement fuel preparation projects are typically designed for medium to large industrial capacities.
Typical RDF shredder capacities include:
• 5–10 tons/hour for small RDF preparation facilities
• 10–20 tons/hour for municipal waste sorting plants
• 20–50 tons/hour for large waste-to-energy preprocessing systems
The actual system capacity depends on waste composition, moisture content, and required RDF particle size. Projects producing alternative fuel for cement kilns often require a stable output of 30-80 mm to ensure efficient combustion.

RDF Shredder Solution Configuration
A complete RDF shredding solution may include:
• Feeding hopper & conveyor system
• Primary low-speed, high-torque shredder
• Secondary shredder (optional)
• Screening system for size control
• Dust suppression & fire prevention system
The configuration is customized based on waste composition and RDF standards.
The RDF shredding system is designed as an integrated solution, combining primary shredding, secondary size reduction, and material conditioning to ensure stable RDF quality for downstream energy recovery applications.
High-Performance RDF Fine Shredder for Cement Plants
For cement kiln co-processing, our RDF fine shredders ensure the final fuel meets strict caloric and size requirements (under 50mm). This combustible mixed waste shredder solution is optimized for textiles and film plastics.
Why Use a Dedicated RDF Shredder?
- Stable RDF particle size
- Reduced equipment wear downstream
- Lower fire risk compared to high-speed shredders
- High throughput with low operating cost
- Reliable long-term operation
- Low Maintenance Cost & High Durability
To reduce the long-term RDF shredding cost, our machines are equipped with:
-
Hardened Alloy Blades: Reversible design to double the service life.
-
Shock-Absorbing Gearbox: Protects the drive system from unshreddable metal contaminants.
-
Quick-Change Screen: Allows operators to switch RDF output sizes (e.g., from 80mm to 30mm) in under 30 minutes.
