China Fire-Resistant Steel Cord Conveyor Belt

Characteristics and uses:
Fier-resistant steel cord conveyor belt has the merits of conveying materrials at the occasion of high strength
,long distance,and large load as common steel cord conveyor belt.However,it also has the properties of filre-
resistant and anti-static,and it is suitable for fire resistant and anti-explosion applications, especially suitable
for conveying materials under coalmine wells.
