FIRE-RESISTANT STEEL CORD CONVEYOR BELT FOR COAL MINING
Product Property
Steel cord conveyor belt is suitable for high strength, long distance, heavy loading transportation of materials, which are widely used in coal mineral, mines, metallurgy, electricities, ports, chemical industries, etc. It has the following characteristics:
1. High tension strength: the belts are suitable for large span, long distance transportation of materials.
2. Small elongation in use. the belts only need a very short take-up stroken distance.
3. Small diameter of driving pulleys.
4. High adhesion between steel cord and rubber cover. the steel cords are coated with zinc on the surface. the rubber cover is tightly adhered to the steel cords, , and is resistant to shock and difficulty to drop.
5. Stable tension of steel cords. the belts are balanced in running and dificult to run in deviation.
6. Good troughability. the belt can transport more materials and prevent the materials from escaping.
Fire resistant steel cord conveyor belt are of the same structure as normal steel cord conveyor belt. But it adapts the fire resistant rubber cover. This belt is suitable for the area of fire prevention, explosion-proof and spontanerous combustion and firing easily, which is mainly used to convey coal ming underground with long distance, large loading and high strength.
