Foundry owners, in particular, could write a book about it: Any change of direction of the sand during pneumatic transport may turn into a problem spot, especially when it comes to the use of impact absorber or flow diverter. Caking or swirling not only interrupt the steady transport of the sand, but also cause increased wear in these areas and – owing to the feed pressure - additional energy consumption. At last, there is an end to this. The drawn ceramic bends manufactured by Th. Scholten eliminate offsets, staggered edges or jolting. The sand can be transported without any obstacle and caking or swirling is a thing of the past. The wear protection specialists from Wülfrath assure the customer of a continuous nominal bore diameter without segment bends, with radii and flanges manufactured to customer requirements. Even a radius below 500 mm poses no problem.
