China Steel Cord Conveyor Belt for Long Distance Transportation

Steel cord conveyor belt
Usage:
Steel cord conveyor belts are widely used in high strength,long distance and heavy load transportation of
materials,and they are also used in high strength and short distance transportaion of materials on special
occasions.

Characteristic:
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 bely body 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 qood adhesion with steel cords.Therefore,the rubber is tighrly adhered to
the steel cords and is resistant to shock and difficult to drop,so the rubber belts are long in 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 awry.
6.Good troughability:As the belt body has no transverse skeleton,it is easyv to from a deep trogh,so the belts
can load more materials and prevent the materials from escaping.
7.Good troughability:As the belt boby 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 X-rays to inspect damages of the skeleton steel cords on the
conveyor machines to prevent accidents from happening.
