Aumund, Rheinberg, Germany, points out that the mechanical demands on steel-cord bucket elevator belts are fundamentally different to those of belt conveyors. During more than 30 years the company has continuously refined belt bucket elevator technology and offers nowadays the strongest and most effective solutions worldwide for vertical transport of bulk materials. The belt of a bucket elevator needs to provide high tensile strength, a low net weight and low elongation, while simultaneously running in good alignment. This is achieved by a specialised production process and above all by high transverse rigidity.
 

Last year the company replaced an existing bucket elevator at India’s largest and most modern cement plant belonging to the Ambuja Cement Group with a high performance Aumund belt bucket elevator. This has a lift height of more than 170m, a conveying capacity of more than 650t/h of raw meal (15,600t daily capacity), operating 24 hours, 7 days a week. The bucket elevator belt has to be optimally designed for its attachments like buckets, rubber seals and endless splices in order to function as a reliable complete system in daily operation, even after many years. Such belts provide strength up to 4200N/mm for lift heights of more than 200m. The exceptional quality of these Aumund steel-cord belts is successfully on trial daily with 3600 reference installations worldwide. www.aumund.com
