They are made up from a tubular trough that is 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 a coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft sealing unit (one of the bearing assemblies incorporated in the drive unit), a number of intermediate hanger bearings depending on the overall length of the screw conveyor.
Furthermore, ES Screw Conveyors are equipped with a gear motor that suits the application.
ES Screw Conveyors are of the medium-heavy-duty type.
Function of ES Cement Screw Feeders
ES Screw Conveyors are used for feeding or conveying of cement and filler dust in concrete batching plants, cold filler dust in asphalt mixing plants, as well as cement and similar materials in building materials processing plants.
