With the introduction of an in-house developed transfer point seal for belt conveyors, the German manufacturer Schulte Strathaus can now offer integral solutions for conveying systems.
André Hanke, general manager of the Starclean division of F. E. Schulte Strathaus GmbH & Co. KG (Fess Group), explains the special character of the new transfer point seal. Its unique design is based on the use of two different kinds of polyurethane. Hard polyurethane is used for guiding the material and softer polyurethane for the secondary dust seal. During conveying, the dust seal applies light pressure on the belt to prevent dust emissions. The relative softness of the material employed results in low wear on the belt and thus increased belt lifespan. Another feature is that the seal can be adjusted when necessary. “That not only guarantees a further increase in lifespan, but also ensures a continually high level of dust emission prevention throughout its working life”, says Hanke.
