What is a Screw Conveyor?

Screw conveyors are mechanical conveying systems that provide efficient transportation of small particle materials such as dust, granules, sawdust, sand and similar in industrial facilities. These closed-structure conveyors prevent material loss and allow dust-free transportation.

Working Principle

Screw conveyors operate with the movement of a helix structure wrapped around a rotating shaft. Materials are pushed forward by the rotational movement of the helix wings. This process allows transportation in horizontal, inclined or vertical directions.

Sample Applications:

  • Sawdust transportation systems in factories
  • Grain and feed transportation in agricultural facilities
  • Cement and sand transfer in the construction sector

Advantages

  • Closed System Design: Provides dust-free, clean and safe transportation.
  • High Efficiency: Provides maximum transportation capacity with minimum energy.
  • Flexible Operation: It can carry horizontally, inclined and vertically.
  • Long-Lasting Use: Its robust structure requires low maintenance.

Screw Conveyor Types

Type Description
Horizontal Screw Ideal for horizontal transportation at surface level.
Vertical Screw Used when it is necessary to carry materials to a height.
Inclined Screw Allows materials to be carried at a certain incline.
