RDF (Refuse Derived Fuel) shredder blades are heavy-duty industrial cutting tools designed for processing highly abrasive and heterogeneous waste streams. Materials such as municipal solid waste, plastics, textiles, packaging residues, and light metal fractions create far more aggressive wear and impact loads compared to standard shredding applications.
For this reason, RDF blades must deliver an optimal balance of high toughness and superior wear resistance through advanced metallurgy and controlled heat treatment.
Yalman Knives RDF shredder blades are engineered for single-shaft and twin-shaft industrial shredders, providing extended service life under demanding alternative fuel production conditions.
Application Area: RDF production plants, recycling facilities, alternative fuel preparation lines
Processed Materials: Plastics, textiles, packaging waste, rubber, light metal mixtures, municipal waste fractions
Steel Grades: Alloyed tool steels optimized for toughness–wear resistance balance
Heat Treatment: Vacuum heat treatment with controlled tempering
Hardness Range: Optimized HRC levels depending on application
Manufacturing Process: Precision post heat treatment machining
Design Compatibility: Fully interchangeable with OEM designs or performance-enhanced geometries
In RDF lines, blades do more than cut. They are continuously exposed to:
Impact loads
Abrasive particles
Constant mechanical stress
Occasional foreign metal contamination
Under these conditions, low-quality or poorly heat-treated blades typically suffer from:
Premature edge chipping
Rapid wear
Crack formation
Frequent blade replacements
Yalman RDF shredder blades are manufactured with a carefully controlled toughness–hardness balance, ensuring resistance to breakage while maintaining strong wear performance.
✔ Longer service life
✔ Reduced unplanned downtime
✔ Stable cutting performance
✔ Lower blade cost per processed ton
✔ Reliable operation under heavy load
