Steel Cord Flame Resistant Conveyor Belts are suitable for
conveying materials in flame resistant and anti-explosion
occasions, especially in underground coalmines.
Characteristics
Except the advantages of conveying materials at the occasion of
high strength, long distance and large load as the steel cord
conveyor belt, the steel cord flame resistant conveyor belt shall
meet the safety requirements blow.

Flame resistance for mines: suitable for conveying flammable and
combustible dangerous materials. The average value of burning test
shall be less than 10s, and the single value shall be less than
15s. Besides, it has to pass the drum friction test and tunnel
propane combustion test.
