Stainless Steel Tubular Screw Conveyors

Description

The modular Hydroscrew Tubular Screw Conveyor system is highly versatile. TX Screw Conveyors are manufactured in stainless steel with a suitable surface finishing grade appropriate for the application. Manufacture of the fabricated components is carried out on machines that guarantee a perfectly smooth surface due to which material residue is reduced to the minimum. TX Tubular Screw Conveyors are made up from a tubular trough that is 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 a coupling bush at each end, two end bearing assemblies complete with adjustable shaft sealing unit, 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 that is suitable 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.

Function

The TX Tubular Screw Conveyor system offers a variety of solutions for conveying or feeding powdery or granular materials. TX Tubular Screw Conveyors are suitable for applications in which any contamination of the material handled has to be strictly avoided and in which absolute cleanliness and perfect resistance to corrosion is 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.
