Screw conveyor

Designed for diagonal or horizontal transport of loose materials. As a universal device it is used in feed factories, but also in other industries including the production of compost, pellets and others.

 

Screw conveyors

The screw conveyors are offered in two versions depending on the shape of the housing:

  • Trough conveyors type “U” in which the unscrewed covers allow you to clean the conveyor or remove any blockages.
  • Tubular conveyors with closed, tight construction.

 

The conveyors consist of the following components:

  • high efficiency drive gear motor with flexible coupling,
  • segments of troughs (pipes) 0.5, 1 and 2m long,
  • intermediate bearing.

 

Optional equipment such as:

  • overflow cover with sensor,
  • rotation sensor
  • inlet and outlet connectors.

Depending on the needs, the conveyors can be made of ordinary steel – painted, galvanized or stainless steel.

 

Different applications with different flight & pitch 

Conveyors are most often made with a 1/1 screw pitch (pitch / diameter). Such a jump is the most universal and suitable for transporting most materials.

Conveyors with a screw pitch of 0.7 / 1 are recommended for conveyors that work at an angle and raise material.

Variable pitch screw conveyors used in feeders to achieve a uniform flow and to block the free flow of material.

For viscous materials  single flight ribbon is recommended. The open space between the ribbon and the shaft eliminates the accumulation of material.

TESTMER manufactures screw conveyors with flight/pitch  adapted to the type of conveyed material and its parameters.
