Vertical Screw Conveyor


Cosben specializes in the design, manufacturing, and supply of vertical screw conveyors engineered for the efficient upward transportation of dry powders and bulk materials. Built to handle demanding vertical conveying applications, our screw systems offer reliable performance, minimal footprint, and dust-free operation—even in space-constrained industrial environments.

These conveyors are specifically designed to transport materials at a 90° vertical angle, making them ideal for transferring powders between floors, into silos, or to elevated process machinery. Our vertical screw conveyors are used across industries such as cement, construction, chemicals, and material processing.

Key Features & Benefits:

  • Vertical Transport Efficiency: Engineered to move bulk powders vertically at 90°, ideal for applications where floor space is limited.
  • Dust-Free Operation: Fully enclosed tubular design ensures clean and contamination-free material handling.
  • Heavy-Duty Construction: Built using state-of-the-art manufacturing and precision machinery for long-term, high-performance use.
  • Compact Footprint: Saves floor space while maintaining high conveying efficiency, ideal for plants with vertical layout challenges.
  • Customizable Design: Available in a range of diameters and lengths to suit your plant's requirements.

Salient Features

  • Material Compatibility: Suitable for conveying materials such as cement, fly ash, micro silica, sand, dolomite, gypsum, stucco, and other free-flowing dry powders.
  • Screw Design: Precision-welded continuous flight on central pipe, optimized for vertical lifting with minimal power loss.
  • Robust Drive Assembly: Integrated with high-performance flange-mounted reduction gearbox and TEFC (Totally Enclosed Fan-Cooled) 4-pole squirrel cage induction motor for consistent output.
  • Support Bearings & Sealing: Includes end bearings and custom sealing protection to ensure longevity and minimize wear during vertical movement.
  • Flexible Electrical Setup: Motors are offered in custom voltage and frequency configurations to match region-specific standards.
