Flyash Screw Conveyor

Screw Feeders are manufactured in carbon steel with a suitable surface finishing. Screw Conveyor are made up from a tubular trough that is equipped with at least one universal inlet and one universal / cylindrical 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. Furthermore, Tubular Screw Feeders are equipped with a gear motor that suits the application.FunctionTubular Screw Feeders are highly versatile and offer a variety of standard solutions for handling powdery materials. Depending on the characteristics of the material, different feeder models are available in asphalt plants for handling filler dust or additives.ApplicationTo inject a mixture of cold and hot filler from the filler weigh hopper into the twin shaft mixer, the Screw Feeder should be installed next to or in front of the mixer. It has to feed the mixer quickly and homogeneously with filler to guarantee a high quality of the asphalt.
