What is a Screw Conveyor?

Screw conveyors are mechanical conveying systems that allow efficient transportation of small particles such as dust, granules, chips, sand in industrial facilities. closed-structure screw conveyors prevents loss of material and allow dust free transportation.

Operating Principle

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

Sample Applications:

  • Chip conveying systems in factories
  • Grain and feed transportation in agricultural facilities
  • Cement and sand transfer in construction

Advantages

  • Closed System Design: Provides dust-free, clean and safe transportation.
  • High Efficiency: Provides maximum carrying capacity with minimum energy.
  • Flexible Operation: Can carry horizontally, inclined and vertically.
  • Long-Lasting Use: Robust structure reducing the need for maintenance.

Screw Conveyor Types

Type Description
Horizontal Screw Ideal for surface level, horizontal transportation.
Vertical Screw Ideal for transporting materials to a height.
Inclined Screw Ideal for transporting materials on an incline.
