Product Description

Steel Cord Tear Resistant Conveyor Belt China

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.

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 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.
 

Physical Properties of Rubber Cover (before aging)

Grade	Tensile Strength/Mpa ≥	Breaking Elongation/% ≥	Abrasion Loss/mm^3≤
H	24	450	120
D	18	400	100
L	15	350	200
Note:Grade H-used for transporting sharp, abrasive materials which can damage belts badly.Grade D-used for transporting highly abrasive materials.Grade L-used for transporting medium-abrasion materials.

After-aging properties of rubber cover(70ºC×7d):

Tensile strength and breaking elongation are both not lower than 75% of before-aging values.
 

Adhesion

a. Adhesion between rubber cover and belt core: ≥12N/mm.
