Screw Conveyors and Transfer Screws

Screws Conveyor Transfer for Powder and Granule Transport

What is a Transfer Screw or Screw Conveyor?

Also known as Archimedean screws, these screw conveyors are mechanical transport systems used to move dry, powdered, or granulated materials. With a modular design, they are suited for demanding industrial environments such as food processing, chemical, construction, and recycling industries.

Common applications

• Food processing: Conveying flour, sugar, spices, and similar products.
• Chemicals: Tubular screw conveyors for abrasive or corrosive chemicals.
• Construction: Tubular conveyors for cement, sand, and lime.
