Steel cord conveyor belt

 

one purpose: 
Steel cord conveyor belt, for high strength, long distance, and mass transportation of materials occasions. In special circumstances, also apply to high-intensity, short-distance transportation of materials.

two. Features: 
1 High tensile strength: for single-span, long distance transportation of materials. 
2 Use a small stretch: tension required to trip short. 
3 driving rolls of small diameter: with a core layer of longitudinally by a skeleton made of wire rope, resistant to flex fatigue. It can be equipped with a smaller diameter roller, the device compact. 
4 rubber with good adhesion rope: the surface of galvanized steel wire rope, while the use of wire rope has excellent adhesion with the rubber, bonded together with rope, impact resistance, easy off blocks, long service life. 
5. Rope tension is even: As advanced manufacturing technology, arranged in uniform rope tension, running balance, easy to deviation. 
6 into the slot performance: with a core of non-horizontal frame, easy to form a deep trough, install more material, and to prevent scattering. 
7 available X-ray examination: the skeleton in the conveyor rope, used X-ray detection, to prevent accidents.
