Trough Screw Conveyor
A horizontal conveyor with the flow area open to view, for powders that need looking at, cleaning out, or simply checking on between shifts.
Type U or V trough
Direct chain or belt drive
Horizontal or slightly inclined
Anti-wear coating option
Trough profile
U-shaped or V-shaped, chosen on how the material flows
Drive
Direct, chain or belt, chosen on speed and torque
Orientation
Horizontal, or slightly inclined to suit the layout
Best for
Cohesive, dusty or build-up prone powders needing regular access
An Open Trough, So You Can See What the Material Is Doing
Cosben Engineering manufactures trough screw conveyors designed for reliable handling of powders and bulk materials in industrial environments. These systems are commonly used for horizontal material transfer and can also be configured for slight inclinations depending on plant requirements.
The open type screw conveyor design provides easy access to the material flow area, making it suitable for applications where inspection, cleaning, and maintenance are required on a regular basis. This makes it a practical solution for handling powders that may be slightly cohesive, dusty, or prone to buildup.
Used across industries for materials such as cement, fly ash, sand, dolomite, gypsum, and biomass, the system ensures stable conveying performance while maintaining operational flexibility. Whether applied as a horizontal screw conveyor or part of a larger trough screw conveyor system, it integrates easily with feeders, hoppers, and downstream equipment.

Key Features & Benefits
Five reasons an open trough is specified instead of a closed tube.
01
Designed for Powder & Bulk Material Handling
Handles materials such as cement, fly ash, microsilica, sand, dolomite, gypsum, and similar bulk solids.
02
Flexible Trough Configuration
Available in U-shaped and V-shaped trough designs to suit different material flow characteristics.
03
Accessible Open Design
The open trough auger conveyor structure allows easy inspection, cleaning, and maintenance.
04
Stable Horizontal Conveying
Optimized for use as a horizontal screw conveyor with consistent material movement.
05
Low Maintenance Operation
Designed for long service life with minimal downtime in industrial environments.

Salient Features
The five build decisions taken before a conveyor is cut, from trough profile to drive.
- Drive Options. Can be configured with direct drive, chain drive, or belt drive systems depending on speed, torque, and installation constraints.
- Trough Design Selection. U or V-shaped troughs selected based on material flow properties and discharge requirements.
- Robust Construction. Fabricated using durable materials, with optional anti-wear coatings for abrasive applications such as coal or biomass conveying.
- Precision Manufacturing. Built with tight tolerances to ensure smooth, vibration-free operation over long periods.
- Versatile Installation. Suitable for horizontal and slightly inclined installations depending on process layout.
