Mining industry is a kind of natural habitat for SIG and its items, as a matter of fact, it has been supplying rubber conveyor belts all over the world since its day one.
This is mainly due to its wide products range in terms of different carcass construction possibilities and rubber compounds such as abrasion, heat, and fire resistant as well.
The use of rubber conveyor belts in mining industry commonly accomplished two functions:
To summarize, rubber conveyor belts for mining industry must handle material to improve and to optimize extracting process, meanwhile they enable end users to cover long distances without using trucks. Two main advantages emerge:
Conveyor belts for mining industry are products requiring an extremely detailed design as many aspects must be analysed and considered to provide customers with the most suitable product matching with their requirements.
The first issue to be tackled is the one about above ground or underground application: as a matter of fact, it is crucial to clarify this aspect to understand if strict safety laws in terms of specific rubber quality must be followed or not.
In case it dealt with an underground installation, it would be compulsory to guarantee that in case of fire explosion the belt would not be an active fire source propagation.
Afterwards, the second aspect to be analysed is the one concerning belt type construction: based on the overall length of the conveyor system, to reduce problems connected to elongation, technical department will have a key role in suggesting whether the belt must be textile or steel cord.
Normally, if you must handle materials for more than 500 meters, it is recommended to rely on a steel cord belt that guarantees low elongation combined with an excellent longitudinal flexibility.
As claimed at the beginning of this paragraph, it is fundamental to determine if the concerned application will be an above-ground or underground one: if the second case was confirmed, to match with strict safety requirements, no other rubber quality than flame resistant ones would be accepted (for more detailed explanation, please read below).
In 2014, the European Union adopted specific laws concerning industrial materials and spare parts installed inside areas where there is a close connection between surrounding atmosphere and explosives. These laws named ATEX must be respected in industrial plants where the above-mentioned connection could cause a potential fire explosion that would be seriously harmful/dangerous for all workers, threatening their lives.
For this reason, on underground site, it is compulsory to rely on one only possible rubber compound to manufacture a conveyor belt.
This specific compound must be a fireproof product (matching with V degree of DIN 22102 laws) because it avoids the belt from burning and from triggering centres of fire.
During the years, SIG has managed to establish its brand as a benchmark in mining industry since it has supplied an incredible number of mines all over the world, handling different many different products, but always satisfying customers’ expectations.
