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.
