Computersimulation von Wendelförderern mit Hilfe der Diskrete Elemente Methode (DEM)

Abstract

Spiral conveyors are mainly used in clarification plants for screenings and sludges, in waste recycling and disposal, in the timber industry (wood splints and chips), in the food industry and agriculture (seeds), in the cellulose, paper and construction industry (plaster), etc.. In modern closed loop recycling management and cleanup operations (processing of dumpsites, etc.) spiral conveyors are of special importance and an important link within the logistic chain of a waste recycling plant. The lecture describes this role and presents the results of experiments. Furthermore, it deals with the DEM simulation of spiral conveyors and points out the chances and possibilities opened up by an improved design of spiral conveyors.
