Screw conveyors – compact bulk material conveyance with integrated process technology

Screw conveyors are used to discharge and transport nearly all bulk materials including fibrous and paste-like products. They move bulk material with a rotating, spiral conveying screw in a trough or a tube trough.
The advantages of screw conveyors are low susceptibility to failure, low costs, low space requirement and dust-free transport.

They also offer the possibility to feed and remove flexibly transported goods along the conveyor line. Various designs are available for steep inclined and vertical conveying as well as for work processes such as mixing, stirring, washing, sieving, heating and cooling.

Performance specifications for all designs

  • dustproof and product sealed
  • gas and water tight
  • pressure surge protected
  • robust design
  • design in accordance with Atex (dust explosion classes)
  • low space requirement
  • low maintenance requirement
