FLAME RETARDANT STEEL CORD CONVEYOR BELT FOR COAL MINING
Product Property
The Flame-retardant steel cord rubber conveyor belt for coal mining underground is used for the higher strength, less elongation galvanized steel cord, whose top and bottom surfaces are covered with flame-resistant and anti-static rubber material. The configuration is moulded in invariable tension. It can convey materials in flame-resistant and anti-static enviroments after being vulcanized. This belt has excellent performances, such as fire-resistant, high strength, less enlogation and good flexibility and throughability. It is suitable for conveying materials at the occasion of long distance, high speed, large loading, and high strength in fire-resistant antistiatic enviroments, such as coal mining underground.
