With the innovative AirScrape conveyor sealing, spills and dust at transfer points in conveyor systems and belt damage are a thing of the past. Innovative and sustainable.
In the minerals and mining industry, contamination of conveyor systems and dust generation during operation are a well-known problem. Conventional conveyor skirtings at belt transfer points can help here, but even friction forces quickly wear them out; they lose their effect and also damage the belt of the conveyor during long-term use. This in turn increases the costs for maintenance or replacement. And it does not matter if you are think about a simple rubber, a single or a double skirting. The conventional belt sealing are working all to the same prrinciple, with more or less pressure to the belt. The new conveyor-skirting the AirScrape from ScrapeTec Trading Ltd. is quite different. It represents one of the rare innovations in this industrial sector, is virtually maintenance-free, increases the service life of conveyor belts and permanently saves cleaning efforts. Beyond the chute and conveyor belt, the AirScrape ensures more cleanliness. And finally it is a big gift in regards to Safety and Health care for the service and maintenance people.
If you see the AirScrape conveyor-skirting in use, you can quickly see the minimum distance between the individually adjustable sealing lip and the belt. Critical observers immediately suspect a permeability for material and dust. But this is exactly where the AirScrape's operating principle and thus its uniqueness lies. An intelligent lamella structure on the underside of the 2 m long seal skirting unit ensures that, thanks to the Venturi concept, a vacuum is created in the conveyor area on the belt. Nothing can escape through the millimeter-thick gap because the negative pressure allows air to flow in. There is a constantly airflow from the outside to the inside through that little gap between the belt and the AirScrape conveyor-skirting. This makes the AirScrape the first belt sealing that works without contact to the belt.
The AirScrape conveyor-skirting consists mainly of polyurethane, available in the standard version but also in other different qualities, for example in antistatic and flame-retardant, or food grade material, but also for high temperature. Due to its special resistance, the belt sealing AirScrape is theoretically maintenance-free. It can be used permanently without maintenance. Exceptional mechanical influences caused by the conveyed material can of course also affect the Conveyor-skirting the AirScrape. But in principle the investment is secured by the design. As far as costs of the AirScrape belt sealing are concerned, these are higher than for conventional belt seals. However, considering Total Costs of Ownership, the system pays for itself very quickly. Because the protection against soiling of the conveyor systems and wear of the belts will save considerable costs and also resources such as cleaning personnel. The AirScrape conveyor skirting also effortlessly meets the requirements of health and safety guidelines at work by greatly reducing dust generation and contamination.
In the end, everything that is omitted by using the AirScrape saves costs:
The conveyor-skirting AirScrape can be extended with the DustScrape in production areas with particularly strong dust generation. Support arches can easily be mounted to an existing AirScrape installation. A close-meshed, antistatic and resistant plastic fabric is then applied to it, retaining the dust in the belt area. This reduces the risk of deflagration and damage to the respiratory tract extremely. In future, DustScrape will also be available with an alternative stainless-steel mesh, which offers a further safety advantage due to its non-flammability.
The Conveyor-Skirting the AirScrape is another innovation of the developer Wilfried Dünnwald, who is always on the lookout for new solutions for problems in stripping technology and conveyor systems. His expertise was shaped by mining studies and 25 years of professional experience underground as a machine business unit manager. In addition, he has a special passion for the stone and earth industry. His company ScrapeTec develops the innovations and holds the patent rights. The distribution of the AirScrape, the DustScrape, as well as the TailScrape, lies with ScrapeTec Trading Ltd. and is thus in the hands of the developer, as managing partner of the company. Further products are being planned
