Stainless Steel Tubular Screw Conveyors TX

TX Stainless Steel Tubular Screw Conveyors offer a variety of solutions for conveying or feeding powdery or granular materials. They are suitable for applications in which any contamination of the material handled has to be strictly avoided and where absolute cleanliness and perfect resistance to corrosion are required.
In particular, TX Tubular Screw Conveyors are used in environmental technology, in flour and animal feed milling, in food processing and packaging, in plastics and chemicals, as well as in the pharmaceutical industry.

Technical Features


The modular TX Tubular Screw Conveyor system is highly versatile. TX Screw Conveyors are manufactured from stainless steel with surface finishing grade suitable for the application. Manufacture of fabricated components is carried out on machines that guarantee a perfectly smooth surface which is why material residue is reduced to the minimum. TX Tubular Screw Conveyors are made up of a tubular trough equipped with at least one inlet and outlet spout, an end plate at each tube end, helicoid screw flighting welded on a centre pipe with coupling bush at each end, two end bearing assemblies complete with adjustable shaft seal, and a number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, TX Tubular Screw Conveyors are equipped with a gear motor appropriate for the application. Depending on the material to be handled, TX Tubular Screw Conveyors come in a light or medium heavy-duty design.
TX Screw Conveyors are available with ATEX, Zone 22 certification.
