  SCREW CONVEYORS & FEEDERS -- [ Tubular Screw Conveyors ]
Description :

The modular Tubular Screw Conveyor system is highly versatile offering numerous solutions for conveying powdery or granular materials. Tubular Screw Conveyors are manufactured in carbon steel with a suitable surface finishing. 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, a certain number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, Tubular Screw Conveyors are equipped with a gear motor that suits the application. Tubular Screw Conveyors come in a medium-heavy-duty design only.


Functions:

The light-duty version is mainly used for conveying of powders or granular materials in the production of pet-food, in the plastics industry, and in soap, washing powder and detergent processing. The medium-heavy-duty version is mainly used in animal feed milling, in wood processing, in the chemical industry, and in environmental technology for both municipal and industrial applications. The extra-heavy-duty version is mainly used in the cement / lime /gypsum, as well as in the mining industry. Depending on the application various types of screws, inlet and outlet spout models are available.

The Tubular Screw Conveyor system is highly versatile and offers a variety of standard solutions for handling of powdery or granular materials. Depending on the characteristics of the material different models of conveyors or feeders are available in applications like concrete production (cement, fly-ash, filler, silica fume), asphalt production (hot and cold filler), premixed building materials (plasters, sand, cement, additives), glass processing (calcium carbonate, soda, sand, etc.), foundries (sand, bentonite), and many others.
