Hebei BAO’s NN Conveyor Belts are engineered with both warp and weft fibers made of Nylon, providing exceptional resistance to impact, fatigue, and damage. While featuring a higher working elongation than EP, NN belts offer superior flexibility and excellent resistance to groove formation and mechanical damage. This makes them perfectly suited for applications involving frequent heavy material drop heights, sharp impact, and installations with shorter radius curves. NN belts are a highly durable and cost-efficient option for tough environments.
Key Features
- Extremely High Impact Resistance
- Excellent Transverse Flexibility
- Good Resistance to Acids
- Superior Tear and Rip Stops
- High Tensile Fatigue Resistance
- Simple and Quick Splicing
Applications & Industries
Quarry and Stone Crushing
Designed to absorb heavy impact from dropped rock and aggregate materials effectively.
Fertilizer Production
The nylon carcass offers better resistance to mild acids and corrosive chemical dust.
Mobile Crushing Plants
Superior flexibility allows NN belts to navigate the frequent twists and turns of mobile systems.
Iron Ore and Slag
Handles sharp, abrasive material impacts efficiently, reducing belt wear and replacement frequency.

FAQs
1. Why should I choose an NN belt over an EP belt?
Choose NN if your primary concern is high-impact resistance and flexibility, as NN absorbs impact better due to its higher working elasticity.
2. What is the main drawback of NN belts?
The main drawback is a higher working elongation (stretch) compared to EP, meaning they may require more frequent take-up adjustments, especially on new belts.
3. Are NN belts better for portable or mobile conveyors?
Yes, the superior transverse flexibility of NN makes it ideal for portable or mobile conveyors that require frequent re-routing and have small diameter pulleys.
4. How is the rubber compound different for NN belts?
The rubber compound for NN belts is often formulated to enhance anti-tear properties and impact dampening, complementing the nylon carcass strength.
