Specialists for transfer points of conveyor systems

摘要

Anyone who, like the graduate engineer Wilfried Duennwald, looks back on many years of working as a miner in a manager­ial position knows the potential problems at transfer points of conveyor systems first-hand. It makes no difference in which industry the continuous conveyor technology trans­ports bulk materials. It also makes no difference whether it works underground or open pit. Spillages or dust emissions are a nuisance for all industries. In order to be able to con- tain both of these problems permanently and at the same time without an exponential increase of the maintenance ef­forts for the skirtings of the transfers used for this purpose, Wilfried Duennwald brooded intensively over various techni­cal principles. This basic self-study of the options included a strict exclusion procedure. What would have been the point of developing a further, basically similar technical solution to the ones already in place? The inventor's own specifications were therefore also concerned with elimi­nating the well-known unfavorable side effects of existing systems.
