Conveyor Idler
Technoroll delivers complete conveyor solutions for modern mining and heavy industry. From Steel Rollers Low Friction to advanced composite rollers — including HDPE Glass-Filled, UHMWPE, and HDPE FRAS — our solutions are engineered to support modern mining by improving material flow, extending service life, and reducing maintenance costs. Precision-engineered Frames and heavy-duty Pulleys ensure stability, efficiency, and safety across demanding operations. Supported by official TKDN certification, Technoroll combines the proven strength of steel with the innovation of composites to deliver maximum productivity and reliability for today’s mining challenges.
Every Technoroll product prioritizes long-term reliability and efficiency, supported by four key advantages:
- Low Friction – The non-contact seal system ensures smooth rotation with minimal friction.
- Extreme Durability – Premium materials such as HDPE glass-filled, UHMWPE, FRAS composite, and high-grade steel provide strength and extended service life.
- High Safety – FRAS materials with anti-static and self-extinguishing properties offer protection in high-risk environments.
- Precision Engineering – Finite Element Analysis (FEA), robotic welding, and dynamic balancing ensure stable performance with minimal vibration.
