TU - Tubular Screw Conveyors

Project Description

Description - The modular TU Tubular Screw Conveyor system is highly versatile offering numerous solutions for conveying powdery or granular materials. TU Screw Conveyors and Feeders 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, helicoids 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 number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, TU Tubular Screw Conveyors are equipped with a gear motor that suits the application. TU Tubular Screw Conveyors come in a medium-heavy-duty design only. TU Screw Conveyors are available with ATEX, zone 22 certification.

Function - Depending on the characteristics of the material different models of conveyors or feeders are available in applications like concrete production (cement, fly-ash, filler dust, silica fume), asphalt production (hot and cold filler dust), premixed building materials (dry plasters, sand, cement, additives), glass processing (calcium carbonate, soda, sand, etc;), foundries (sand, bentonite), and many others.
