Cement Screw Conveyors are manufactured from carbon steel with suitable surface finishing and powder coating. They are made up from a tubular trough equipped with at least one inlet and outlet spout, a welded flange at each tube end, helicoid screw flighting welded on a centre pipe with coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft seal (one of the bearing assemblies is integrated into the drive unit), and a number of intermediate hanger bearings depending on the overall length.  Screw Conveyors and Feeders are equipped with a gear motor that suits the application. Screw Conveyors and Feeders are used for conveying or feeding cement and materials similar to cement mainly in concrete batching plants but also in other building materials processing plants.
