Products Description
Refuse-Derived Fuel (RDF) production requires a stable, uniform, and high-calorific output to ensure reliable combustion in cement kilns, power plants, and industrial boilers. As the core subsystem of a Waste-to-Energy (WtE) line, the RDF shredder must process heterogeneous combustible waste into consistent fuel with a controlled particle size.
Core Technology: Single-Shaft vs. Double-Shaft
Depending on the material toughness and required output, we configure the solution using two primary drive systems:
-
Double-Shaft Shredder: Engineered for Primary Shredding of bulky mixed waste. It utilizes high torque and low speed to break down tough materials like tires and large plastic containers.
-
Single-Shaft Fine Shredder: The preferred choice for Secondary Shredding to reach final fuel specifications (<50mm). Features a hydraulic pusher system for consistent feeding against the rotor.
Technical Role in the RDF Production Line
The shredder is not a standalone machine but a strategic unit typically installed after MSW sorting or MBT (Mechanical Biological Treatment) systems. Its primary functions include:
-
Particle Size Homogenization: Reducing material to 30–80 mm based on end-user requirements (e.g., pneumatic injection for cement burners).
-
Material Liberation: Improving fuel homogeneity to ensure stable downstream combustion and consistent calorific value.
-
System Protection: Reducing equipment wear on downstream conveyors and air-lock feeders.
RS Series Specifications (2026 Models)
Our RS series shredders are engineered for high-availability, 24/7 operation in industrial environments.
| Model | Capacity (TPH) | Main Power (kW) | Output Size (mm) |
| RS-1200 | 5 – 10 | 75 – 90 | 30 – 50 |
| RS-1500 | 10 – 25 | 110 – 132 | 40 – 80 |
| RS-2000 | 25 – 50 | 160 – 200 | 50 – 100 |
Optimized for OPEX: Durability & Maintenance
To ensure long-term system reliability and lower the Total Cost of Ownership (TCO), our industrial RDF shredders integrate:
-
Hardened Alloy Blades: Reversible design to double the service life before requiring replacement.
-
Shock-Absorbing Gearbox: Protects the drive system from catastrophic failure when encountering unshreddable tramp metal contaminants.
-
Quick-Change Screen: Allows operators to adjust output sizes (e.g., switching from 80mm to 30mm) in under 30 minutes to meet different offtaker standards.
Selection Factors for Project Owners
The investment in an RDF shredding system is project-based. When requesting a technical configuration, the following factors are critical:
-
Waste Composition: Ratio of film plastics to textiles (affects blade geometry).
-
Moisture Content: High moisture affects throughput and requires specific pusher logic.
-
End-User Requirements: Different cement plants have strict limits on particle size and chlorine content.
-
Integration Scope: Whether the unit is a standalone machine or part of a full EPC turnkey line.
FAQ
-
Q: Can the RS-1500 handle high-moisture MSW fractions?
-
A: Yes. By adjusting the high-torque parameters and using anti-clogging screen designs, the RS-1500 maintains stable throughput even with the high-moisture waste typical in tropical regions.
-
-
Q: What is the typical blade life when shredding mixed plastics?
-
A: Depending on the abrasive content (e.g., sand/grit), our hardened alloy blades typically offer 500+ hours of operation per edge before requiring rotation.
-
-
Q: Is the system compatible with cement kiln co-processing?
-
A: Absolutely. Our fine shredders are specifically optimized to produce the <50mm fraction required for efficient calciner combustion.
