Purpose:
General purpose flame-retardant steel cord conveyor belt is suitable for material conveying in coal washing plant, power plant and non coal underground mining. It is suitable for conveying massive, granular and powder materials in high strength, long distance and large volume.
Structure:
General purpose flame retardant steel cord conveyor belt is composed of upper covering layer, lower covering layer, steel wire rope, adhesive layer and side glue.
Features:
This product has the characteristics of general flame-retardant, high tensile strength, impact resistance, good elasticity, high wear resistance, small elongation, good adhesion between rubber and steel wire rope, even tension of steel wire rope, good slotting performance, etc. it is suitable for conveying massive, granular and powdery materials under the occasions of high strength, long distance and large transportation volume.
