Standards for steel cord reinforced conveyor belts specifically address the considerations that are unique to them. Very durable due to their design, steel cord conveyor belts are thus used in environments and for payloads where the demands are high enough to warrant their use, therefore requiring thorough test methods that goes beyond what other conveyor belts are subjected to, in addition to

All conveyor belts follow several internationally accepted rubber cover rating systems, most countries follow the German DIN22102 Grade standard, and of course there are regional grade standards, for example, American countries are accustomed to following the RMA grade standard, other countries also have their own overlay standards, such as China’s GB/T7984, Australia’s AS1332, Japan’s

Conveyor belt elongation means that after a period of use, the length of the conveyor belt extends a certain length compared with the original length, which causes the actual length of the conveyor belt to not completely fit the conveyor, and the two are running between There are gaps at times, which affects the overall efficiency of the conveyor.
