High-Torque Single Shaft Shredder for Flexible EPDM & Tartan Flooring Rework
‘
The Challenge: Shredding Highly Flexible, “Elastic” Rubber Slices
A factory specializing in tartan and rubber flooring required a heavy-duty solution to shred EPDM slices (50x300x15mm). EPDM is a notoriously difficult material to process; its extreme flexibility and “tenacious” structure allow it to stretch rather than cut in standard shredders. This engineering challenge often causes conventional machines to jam or experience “wrapping” around the rotor, preventing the efficient size reduction needed for material recovery.

The Solution: Reinforced Single-Shaft Shredder with HARDOX Cutting Technology
We engineered a specialized Industrial Single Shaft Shredder designed to overcome the elastic resistance of high-grade rubber:
We engineered a specialized Industrial Single Shaft Shredder designed to overcome the elastic resistance of high-grade rubber:
- HARDOX Anti-Friction Knives: To ensure a clean “shear” rather than a “stretch,” the rotor is equipped with specialized HARDOX steel knives. These ultra-hard, wear-resistant blades maintain their edge even when processing abrasive rubber compounds, ensuring a consistent cut through 15mm thick slices.
- High-Torque Rotary Action: The single-shaft design utilizes a high-torque drive system and a hydraulic pusher ram to force the flexible EPDM against the rotating knives. This prevents the material from “bouncing” and ensures a steady throughput for the tartan flooring production line.
- Engineering Excellence: By solving this unique “flexibility” challenge, we provided a machine that excels where several other types of shredders fail, offering a reliable path for the recycling of production scrap.

The Result: Efficient, Non-Jamming Rubber Reclamation
The HARDOX-equipped rubber shredder transformed the plant’s waste management. The facility can now successfully down-size its EPDM offcuts into uniform granulate, facilitating a 100% circular manufacturing process for their high-performance athletic and playground surfaces.
