Storing and homogenising bulk material, in particular of inhomogeneous raw materials, such as limestone or coal, is done with the aid of scraper systems of varying design in the bulk material handling industry. Here KettenWulf offers a wide selection of drive and conveyor chains designed specifically for the extreme environmental conditions, such as high shock loads, abrasive and corrosive media, heat and dust. For use in abrasive and corrosive media KettenWulf has developed various sealing systems specifically for the respective application. These seals protect the link area against ingress of dirt, moisture and other media. Service life can be extended with simultaneous reduction of the required maintenance. We also offer scraper chains with external rollers on ball bearings. These rollers are lubricated for life by special sealing elements and can thus be operated maintenance-free. Another advantage of this production method is the option to replace the roller subject to heavy loads under operation independently of the scraper chain and thus further reduce the maintenance effort. In combination with one of the above-mentioned sealing systems the link areas of the scraper chain and the rollers can be protected optimally against harmful environmental influences increasing the service life and reducing maintenance.
Long life chains in all areas
KettenWulf special chains and sprockets enable fault-free operation in the most varied storage systems for bulk material storage, for example in: bridge scrapers, portal scrapers, semi-portal scrapers, side reclaimers and round mixing beds.
