Description
Our Shafted Screw Conveyors are robust systems designed for efficient material handling. These conveyors consist of an Archimedean screw, created by welding a helicoid screw flight to a central shaft. This shaft is driven by a power transmission gear motor, enabling the screw to rotate within a trough. The trough transports material that is loaded through one or more hoppers and directed to one or more outlet spouts, which may be equipped with sliding valves if needed.
The screw is supported by end bearings, which include sealing units when necessary, and may also have a number of intermediate hanging bearings, depending on the conveyor’s overall length.
Trough designs vary and can be tubular, “U” shaped, or “V” shaped, catering to different material handling needs. The power transmission to the screw can be direct, with the gearbox output shaft directly connected to the screw flange, or it can involve a gear motor-chain-flanged shaft system.
Shafted screw conveyors are particularly suitable for transporting a variety of materials, including bulk, granular, and dusty substances, particulate matter, and generally any small-sized bulk materials. They are versatile in their operation, capable of working at angles ranging from 0° to 90°.
Manufacturing materials for these conveyors can include a combination of stainless steel (grades 304 or 316) and high-strength carbon steel. For specific applications, Simeco can provide alternative materials such as AISI 904 or Duplex stainless steel.
Applications of shafted screw conveyors span across various industries, including:
- Concrete production
- Paper mills
- The food industry
- Slaughterhouses
- General industrial plants
To meet diverse operational needs, these units can be equipped with a control panel upon request, available in either electromechanical or PLC-controlled formats.
