Single-screw feeder SU

motorizedlight-dutyfor granulates

Some powders or granular materials are so poorly flowing that they cannot be stored in silos with a circular outlet cone requiring storage in silos with a steeper cone and an oblong outlet opening. SU-type Screw Feeders match the shape of the silo outlet. The trough section is coupled to a tubular section for efficient material feeding towards further processing. According to the cross section of the silo outlet, SU-type Single Shaft Screw Feeders are available with standard U-shaped or with flared V-section trough. In a light-duty version, SU-Feeders are used for flour and materials with similar bulk density and properties. For animal feed and similar products a heavy-duty version is available. SU Screw Feeders are available with ATEX, Zone 22 certification. • Light or medium-heavy-duty carbon steel trough in modular flanged sections • Light or medium-heavy-duty carbon steel helicoid flighting welded on centre pipe • Open trough section with drilled WAM standard trough flange; round outlet with WAM standard drilled flange • Powder-coated • Robust cast iron body flanged end bearing assemblies with externally positioned bearings and manually adjustable packing gland seals • Splined or bolted shaft couplings • Drive unit mounted at inlet or outlet end • Direct drives in a compact version, with coupling transmission, or with chain or belt transmission • Maintenance-free intermediate cast hanger bearings with self-lubricating slide bushes
