A screw conveyor is used within bulk handling installations for the controlled transport of bulk materials and bulk solids. The principle is based on the Archimedes screw, where a rotating screw moves the product through a tube or trough. Screw conveyors are applied for horizontal transport, inclined transport and vertical transport.

Characteristics of screw conveyors:

Multiple inlet and outlet points possible
Execution in tube or trough
Suitable for controlled transport over short to medium distances
Possibility for accurate dosing with an integrated dosing screw

Functions of screw conveyors

A screw conveyor can fulfil several functions within a process line.

Transport: horizontal, inclined or vertical
Dosing of bulk material
Mixing of product streams
Conditioning of product by cooling or heating
