GENERAL USE


Steel cord conveyor belts carry loose and lump materials on heavy duty conveyors over long distances and under severe conditions of use where require high tensile strength anf low elngation used in all industrial sectors such as cement industry, coal mines, power plants,

DATA FOR COVER GRADES OF STEEL CORD CONVEYOR BELT

Abrasion, Impact weather resistant and general use accroding to DIN 22131

Cover Tensile strength (MPa) Elongation (%) Abrasion loss (mm3) Hardness (Shore A) Use
Group Grade          
1 X ≥ 25 ≥ 450 ≤ 120 - For abrasion, impact and weather resistant
W ≥ 18 ≥ 400 ≤ 90 -  
2 Y ≥ 20 ≥ 400 ≤ 150 - For abrasion, impact and weather resistant
3 068 ≥ 15 ≥ 350 ≤ 150 60 ± 5 For general use
4 438 ≥ 15 ≥ 350 ≤ 150 67 ± 5

 

 


Beside their high tensile strength and low elongation, steel cord conveyor belts are reinforced with a special transverse anti-tear steel mesh with an aim to anti-tearing belt length during use.
