Tubular Screw Feeders
The modular tubular screw feeder system is highly versatile offering numerous solutions for conveying powdery or granular materials. Tubular screw conveyors and feeders are manufactured in carbon steel with a suitable surface finishing. Also, 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 number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, tubular screw conveyor and feeder systems are equipped with a gear motor that suits the application.
In addition, the tubular screw conveyor and feeder 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 in the 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.
