A、Usage
Steel cord conveyor belts are widely used in high strength , long distance and heavy load transportation of
materials, and they are also used ini high strengh and short distance transpostation of materials on specail
occasions.
B、Characteristics
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 belt body has a layer of longitudnally arranged steel cords as its skeleton,
and thus is flexble and fatigue - resistant. Therefor, drive pulley of smaller diameter can be used to make the
equipment smller
4. High adhsion between rubber and steel cord: The steel cords are coated with zinc on their surface, and also
the rubber has the property of good adhesion with steel cords , Therefore the rubber is tightly adhered to the
steel cords that is shock resistant and hard to peel off, which make the belt long life.
5. Even tension of steel cords: Out of our advanced techniques in manufacturing , the steel cords are very equably
arranged and have the same tension ,so the belts are well balanced in running and difficult to run away.
6. Good throughability: As the belt body has no transverse skeleton, it is easy to form a deep trough , so the beltscan load more materials and prevent the materials from escaping.
7. Inspection of the belt with X-rays: Users can use X-rays to inspect damages of the skeleton , the steel cords onthe conveyor machines to prevent accidents. |
| Technical parameters： |
