1. STEEL CORD CONVEYOR BELT
|
Steel cord conveyor belts are suitable for high strength, long distance, and heavy load transportation of materials, which are widely used in coalmines, mines, ports, metallurgy, electricity, chemical industries, etc.
1. High tensile strength: The belts are suitable for large span, long distance transportation of materials.
2. Small elongation in use: The belts need only a very short take-up stroke distance.
3. Small diameter of drive pulley: The carcass 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 smaller.
4. 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 service life.
5. Even tension of steel cords: Out of our advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run deviation.
6. Good troughability: As the carcass has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from escaping.
7. Good troughability: As the belt body has no transverse skeleton, it is easy to from a deep trough, so the belts can load more materials and prevent the materials from escaping.
8. Inspection of the belt with X-rays: Users can take X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.

IW conveyor belt is suitable for ore handling, quarries, coal and ore terminals which requiring impact resistant and anti-tear properties; metallurgical sintering and coke plants requiring high temperature resistant properties; and bucket wheel machine handling which requiring high flexibility. SW conveyor belt is suitable for vertical conveying materials, which is widely used in metallurgy, chemical industries, cement, electricity, grain, etc.
1. Structure of special materials provides excellent anti-tear properties
The IW/SW steel mesh structure will make the conveyor belt meet great anti-tear properties which can effectively prevent against being pierced.
2. Excellent impact resistant performance
The IW/SW steel mesh uses elongation type steel in warp and high elongation steel in weft. The outstanding extension of the material will absorb more impact energy and thus provide excellent impact resistant performance.
3. Various cover types
Various types of rubber cover can meet different conditions. High temperature resistant rubber cover has excellent performance in conveying materials under high temperature conditions. But the conveying distance is better to be less than 2km.

2. Solid Woven CONVEYOR BELT
|
It's mainly used for conveying materials in underground coalmines, which can be divided into PVC type and PVG type. For the PVC type, both the top and bottom cover is PVC rubber cover, with the coating rubber thickness of ≥0.8mm and at a slope angle of <16°; For the PVG type, both the top and bottom cover is rubber blends PVC, with the coating rubber thickness of 1.5~4.5mm,and at a slope angle of <20°.
The belt, with great flame resistant and anti-static properties, can fully satisfy the requirements of MT914-2008. The belt uses high strength, low elongation, high quality polyester filament in warp, and high strength, moderate modulus nylon filament in weft. So that the fabric has advantages like high strength, low elongation, light carcass, free of separation of plies, shock resistant, anti-tear, good troughability and so on.
PVG type is covered with covers mainly composed of rubber, which further improves the troughability, resistance to wetness and slip, resistance to low temperature, elongation and wear resistance of the belt. Thus it can not only enhance the slope angle of conveying but also elongate life of belt.
