Fire Resistant Steel Cord Conveyor Belt For General Use - China

Fire Resistant Steel Cord Belt, Coal Mine Steel Cord conveyor Belt, Anti-Tear Steel Cord conveyor Belt Manufacturer

1 - Applications

Fire resistant steel cord conveyor belt is suitable for general uses, such as coal washing plants on the ground, power plants, and non-coal mines under ground.

It should meet requirements of electrical and fire safety properties.

2 - Physical Properties of Rubber Cover

Grade Tensile Strength/Mpa ≥ Breaking Elongation/% ≥ Abrasion Loss/mm3 ≤

H 20 400 200

D 18 400 120

L 15 350 200

Note: Grade H-used for highly-sharp working conditions.

Grade D-used for highly-abrasive working conditions.

Grade L-used for general working conditions.

After-aging properties of rubber cover(70℃×7d):

Change rate of tensile strength & breaking elongation: -25%~+25%.

3 - Adhesion

a.

Adhesion between rubber cover and belt core: ≥12N/mm.
