A tire shredder is not a waste disposal machine; it is a manufacturing plant. The defining specification of your shredder (Output Size, Cut Quality, Steel Separation) determines which market you can sell to.
Attrezzatura correlata: trituratore di pneumatici in gomma.
1. Tire Derived Fuel (TDF)
- Market: Cement Kilns, Pulp & Paper Mills, Utility Boilers.
- Spec: 50mm – 80mm Chips. Steel wire remains embedded (kilns melt it).
- Macchina: Primary Twin-Shaft Shredder.
- Economics: Lowest CapEx ($), High Volume, Low Margin.
- Critical Quality: Clean Cut. “Fuzzy” chips with exposed wire protruding cause handling issues in the kiln feed systems.
2. Tire Derived Aggregate (TDA)
- Market: Civil Engineering (Road embankments, Light Rail vibration damping, Septic fields).
- Spec: 100mm – 300mm Rough Shreds.
- Macchina: Rough Shredder (Primary).
- Economics: Local market driven. High bulk density reduces transport cost.
3. Crumb Rubber Modifier (CRM)
- Market: Rubberized Asphalt (RAC), Sports Turf, Molded Products.
- Spec: <1mm Powder. 99.9% Wire Free. 99.9% Fiber Free.
- Macchina: Primary Shredder -> Secondary Grater -> Granulator -> Milling.
- Economics: Highest CapEx ($$$$), Highest Margin.
- Separazione:
- Magnete a banda larga: Removes 90% of steel chunks.
- Drum Magnet: Removes 9% of fine wire.
- Air Gravity Table: Removes nylon fiber/fluff.
4. Recovered Carbon Black (rCB)
The frontier of tire recycling.
* Processo: Pyrolysis (heating chips in an oxygen-free reactor).
* Materia prima: Richiede 20mm Wire-Free Chips.
* Sfida: Any steel wire entering the reactor will clog the char discharge screw.
* Soluzione: 3-Stage Shredding with extreme magnetic separation.
