U-Trough Screw Conveyor
U-trough screw conveyors move grain, feed and similar granular products over short and medium distances, horizontally or at a low incline, with a rotating screw flight inside a U-shaped trough. The removable top covers simplify maintenance and cleaning, and multiple inlets and outlets allow controlled dosing and distribution.
What Is a U-Trough Screw Conveyor and How Does It Work?
In a U-trough screw conveyor the screw flight rotates inside a covered U-shaped trough and pushes the product toward the outlets. Because several inlets and outlets can be positioned along the trough, the product can be distributed to different points. The removable covers make inspection, cleaning and maintenance of the trough quick and easy.
Key Features
- U-shaped trough with removable covers for easy maintenance access
- Multiple inlets and outlets for distribution along one line
- Speed options suitable for dosing and controlled feeding
- Available in different diameters, lengths and capacities
Applications
- Silo bottom collection and distribution lines
- Process feeding in feed and flour mills
- Dosing and mixing lines
- Feeding points of dryers and cleaning machines
Integration with Plant and Automation Systems
The U-trough screw conveyor connects directly to hoppers, silo gates, weighing units, mixers and dryers. Motor control and level sensors are wired to the automation panel so the line runs in sequence.
Engineering and Selecting the Right Product
Product flowability and abrasiveness, line length, incline, number of outlets and target throughput determine the screw diameter, pitch, sheet thickness and motor power. U-trough conveyors are preferred for horizontal and low-incline lines; tube conveyors for steep inclines.
Frequently Asked Questions
