NN Conveyor Belt
 
The carcass is NN fabric (both warp and weft is nylon fabric). Same with that of  EP belt, NN belt also with the advantage of light in weight, high modulus, impact resistant, low elongation, good flexibility, good troughability, anti-heat, anti-humidity and avoid insect damage, it is suitable for long-distance, heavy-impact and heavy-abrasion material conveying.
 
Application
  • Bulk handling, baggage handling, cement works, coal, foundries, wood working, sand pits, steel industry.
Advantage
  • High resistance to tension
  • Impact resistance
