Take-Up Space for Rubber Conveyor Belt
Item | Elastic Elongation % | Permanent Elongation% | Take-UP Space% |
Steel Cord Conveyor Belt | 0.02-0.06 | 0.08-0.14 | 0.2 |
NN Conveyor Belt | 0.3-0.6 | 1.3-1.8 | 2.4 |
EP Conveyor Belt | 0.2-0.5 | 0.5-1.0 | 1.5 |
3)Good trough ability.Flexible and suitable for the idler with straight run.
4)Good performance,long service life.The single-layer structure,good resistance to flexural fatigue and strong rubber adhesion to the steel cords enable the ST conveyor belts to run at a higher speed than fabric belts.
5)Strong splice,excellent splice efficiency can be obtained by the overlap splicing method.
6)Internal inspection possible.Any damage can be identified though methods such as X-ray photography and to take appropriate measures.
7)Cover rubber,filled with ST or fiber,the rip resistance improved.
