Our
Screw Conveyor
Tubular Screw Conveyors and Feeders have been specially designed to meet the requirements of the food industry. Manufactured from stainless steel, this screw conveyor line offers a high grade of surface finishing. 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. Tubular Screw Conveyors and Feeders are made up of a tubular trough equipped with inlet and outlet spout, an end plate at each tube end, helicoid screw flighting continuously welded on a centre pipe with drive shaft coupling bush, a drive end bearing assembly complete with air or gas-purged shaft seal, as well as a tube cover plate complete with screw fixing quick pin coupling locator for support of the screw at the end opposite the drive unit. Furthermore, Screws are equipped with a gear motor appropriate for the application.
