Schulte Strathaus wins competition for best scraper
Dissatisfied with the quality of scrapers on their new conveyor belt system, the danish recycling company Afatek organised a competition. Five internationally renowned manufacturers took part. The winner is the German firm Schulte Strathaus (Fess Group).
Afatek processes slag. 235 000 tons are processed annually at the recycling companies headquarters in Copenhagen harbour. Waste in Denmark is sorted in various fractions. Even after sorting and incineration, valuable residue can be found in the residual slag. And that is exactly what Afatek salvages. The plant with 52 conveyor belts is housed in a 70 m long, 30 m wide and, at its highest point, 11 m high tent. And in there, says Rysgaard, “it has to be clean”. Unfortunately, that was not the case with the newly delivered conveying system. “We wanted equipment which met our demands. And we organised the competition to find it.” Afatek process slag with different humidity. That is a challenge for scrapers. The test took place with
Rysgaard gave two reasons for Schulte Strathaus outstanding performance in comparison with the other competitors. Firstly, the German manufacturer chose the belt with the widest variety of material, with granulation ranging from 0 – 50 mm. The other competitors chose belts with finer material. But he considers the segmented pressure roller system employed by Schulte Strathaus to be the main reason for their excellent results. This ensures that the metal carbide strip is always correctly aligned to the belt. Rysgaard: “This pressure roller system is a very good solution particularly when belt tension varies, as in our case.” And that is why, continued the project manager, “Schulte Strathaus won the competition.” Now Afatek wants to retrofit the German manufacturer’s Starclean scrapers where ever it makes sence and is possible.
