The large two-pulley-machine for the official testing of the fatigue resistance of conveyor belts and their splices is capable of testing up to around St 14000 belts. Such dimensions are still up in the air though. This huge machine weighs 250 tons.
A new standard for conveyor belts used in underground coal mining of the USA has come into force in 2010.
Get to know an easy, cheap and efficient way to check whether the belt supplied is in accordance with the agreed fire safety requirements.
The ecological advantages of belt conveyors are becoming more and more important..A study of a Mining University reveals interesting facts.
International Mining reported in its October 2008 issue of a new Phoenocord St 10000. Five fully loaded A380 aircraft could be hung on a 2 m wide belt of this type and it would not break. The official tests of the dynamic splice strength at ITA Germany have been passed, and the belt is ready for use.
The strongest conveyor belts so far are operating in Chile.
Have you heard of conveyor belts that negotiate 3D curves? Pipe conveyor belts are getting increasingly interesting, but you must ascertain a reliable manufacturer.

New strongest conveyor belt?
We have got inquiries regarding an "St 8000", 2200 mm wide, which a manufacturer recently publicly claimed to be world's new strongest conveyor belt. It is said to have an actual breaking strength of 8365 N/mm.
The St 7800 mentioned under strongest conveyor belt, however, has a higher breaking strength of 8634 N/mm, following a safety requirement of the DIN standard.
The so-called St 8000 will probably be installed in 2013 only; the St 7800 was commissioned in 1999.
DIN 22101
The belt conveyor design standard DIN 22101 has been slightly revised in December 2011.
The contents are basically as in the 2002 issue.
Copyright violations Established belt manufacturers complain about an increasing number of copyright violations. Mainly emergent Indian and Chinese belt manufacturers are illegally copying illustrations from brochures and websites and use them for their own publications.
Although well-informed users of conveyor belts will detect such wrongdoings, it is an unprofessional behaviour which should be stopped.
