Fire-resistant steel cord conveyor belt has the merits of conveying materials at the occasion of high strength,long distance,and large load as common steel cord conveyor belt. However,it also has the properties of fire-resistant and anti-static,and it is suitable for Fire resistant and anti-explosion applications. Especially suitable for conveying materials under coalmine wells.ST1250 Steel cord conveyor belt
Features and Advantages
1. Lower unit cost of transportation
Fewer conveyors and splices, shorter take-ups, and reduced belt inventory add up to significant cost savings right up front.
Longer belt life, life-long splices, excellent belt training, and reduced downtime save you even more down the road.
2. Small diameter of drive pulley:
The belt body has a layer of longitudinally arranged steel cords as its skeleton,and thus is resistant to flex fatigue.Therefore, drive pulley of smaller diameter can be used to make the equipment more compact.

High adhesion between rubber and steel cord:
The steel cords are coated with zinc on their surface, and also the rubber used has the property of good
adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop,so the rubber belts are long in life.
Steel cord rubber conveyor belt is widely used for coal, mine, port, metallurgy, power station, chemical industry for high strength, long distance and heavy load materials conveying.
