Archimedean screw constructions are fascinatingly simple and effective feeding devices. However, their effectiveness depends crucially on the gap between the screw and trough. Incipient wear quickly results in significant performance loss. Metallic armoring to the screw does not always offer the best repair variant owing to the complex geometries encountered.
We have a solution for problems with wear on conveyor worms! Scope of application: Free-wheel conveyor (without pressure) Elevators Tubular screw conveyors Tray screw conveyors Screw dosing devices KSB Pumps in Test The elastomeric MetaLine coating technology is the winner of the pump coating test carried out by KSB Pumps (Germany). In comparison with 25 competitors our material technique with an up to 35 times higher wear resistance has won through! As the only (!) synthetic coating at all, MetaLine has been classified by KSB as a functional cavitation protection! The erosion resistance was even rated double as high as that of the KSB special material "Noridur"! MetaLine - Technical solutions in detail METALINE SERIES 700 MetaLine Series 700 coatings may protect pressure-less screw conveyors and trays against wear and tear. The feeding media should be at least 1.5 times the size of the clearance in order to prevent jamming between the blades and the elastomeric protective layer. Especially with molding sand processing this seamlessly sprayed on protective system has proven its worth.
MetaLine Series 700 – MetaLine Series 700 coatings can protect pressure-less screw conveyors and troughs against wear and tear. The clearance between the screw and the trough shall be at least 1.5 times as large as the conveyed material to prevent jamming between the wings and the elastomeric protective skin. Non-stick surface properties can prevent the build-up of hard sticky residues. This seamlessly sprayed protection system has proven its worth particularly in the preparation of casting sand.
