Spiral conveyors

Spiral conveyors

A spiral conveyor is a screw conveyor application, in which the actual screw conveyor is comprised of a spring spiral surrounded by an outer pipe made of wear-resistant polyamide (Nylon).

The powder material being conveyed is forced to the centre of the spring spiral, whose high rotation speed moves the material. Although a spiral conveyor can also be installed in an arc, the bend will cause wear if the conveyor is heavily used.

These conveyors offer a light construction and are economical. They are extremely well suited for small conveying capacities (0.5-4 m³/h) and if conveying distances are relatively short (1-13 m).


  • Light, simple construction
  • Reliable operation
  • Long conveying distances are possible (1-20 m)
  • Easy to clean
  • Enclosed, dust-free, hygienic
  • Economical
  • Suitable for use with almost all types of powdered and granular material
  • Also suitable for dosing applications


  • Conveys material from sacks into the process flow
  • Conveys material from stock into the process flow
  • Dosing into weighing tanks
