Screw Conveyors


  • GM Steel Fabricators produce a range of screw conveyors in standard modules to allow full flexibility for any required installation. Screw diameters range from 150mm to 400mm.
  • Casings are normally in mild steel but stainless steel can be used for particular requirements.
  • For minimum maintenance, drive units are mounted directly onto the shaft end thus eliminating problems of chain wear. Screw speed is nominally 100rpm for all sizes.
  • The basic unit comes in 3m lengths and includes:
    • One inlet and one outlet
    • An overflow flap with safety switch.
    • End bearings
    • A direct drive motor reducer unit.
  • Extension modules come as required up to 3m in length. These are supplied with:
    • Intermediate bearing
    • Intermediate shaft
    • Support foot
  • As specialists in screw conveyors, GM Steel can supply a wide range of optional extras for your installation. These include:
    • Additional inlets
    • Additional discharges
    • Discharges with sides
    • Special materials
    • Increased thickness for abrasive materials
