AirScrape conveyor belt skirting, the first installation Case-Study.
Worldwide practical application experience and here the first installation of the first contact free conveyor belt skirting. Since installation nor friction, no wear, no maintenance, no dust, no spillage.
Already in 2012, in response to a specific operator requirement, Wilfried Dünnwald, inventor of this technology, developed the prototype of the AirScrape. The conveyor belt skirting system worked perfectly from the first minute, is still reliably in use today and was ultimately a major factor in the founding of ScrapeTec Trading GmbH.
The AirScrape systems installed on plants in various industries now protect about 1,000 belt transfers worldwide. Parallel to the interest in these units, the number of contractual partnerships is also growing. Trained specialists are on the road everywhere to ensure installation and service. Here is one selected example:
Germany: The solution was perfectly convincing for the operators of a dolomite processing plant, who regularly had to deal with dust and material losses at the transfer from the rotor crusher to the belt. Material spills in the ton range and enormous dust generation were an annoying standard. In addition, there were unfavorable side effects, such as belt wear due to the friction of the former sealing solutions. In contrast, the AirScrape installed in 2013 in the respective transfer was convincing right from the first test run. Even in the long term, the advantages speak for themselves: no spills, no time-consuming cleaning and no maintenance work. In the meantime, it has been proven that the service life of conveyor belts working with AirScrape has increased significantly and the service life of the belt rollers benefits from the dust reduction. The operators confirm even the statement of reduced energy costs for the conveyor systems. The AirScrape first used in Uehrde is still in fail-safe use today. After the DustScrape was introduced to the market, the company decided to equip further transfers with ScrapeTec’s solutions. In North Rhine-Westphalia, the company Inashco extracts marketable mineral recycling fractions from residual ashes of waste incineration in a peripheral branch of the company. The treatment process with different screening and cleaning stages was well coordinated, but also characterized by annoying material leaks at belts and transfers. As the ashes have a high moisture content due to the process, it was not clear to what extent the AirScrape would be able to prevent even such moist and sticky material from escaping. However, a corresponding test was surprisingly successful. In the meantime, the relevant transfers of the plant have been equipped with AirScrape systems. Those responsible confirm that the cleaning effort has been reduced from several hours of daily operation to only two hours per week. Since the introduction of the AirScrape, a good 90 % of the time that once flowed into cleaning duties is now available for productive work.
