Tube Screw Conveyor
Tube screw conveyors move grain and granular products horizontally or on an incline inside a fully enclosed tube by means of a rotating screw flight. The closed body limits dust emission and product loss, offering a compact and economical conveying solution at silo discharge, filling and machine feeding points.
What Is a Tube Screw Conveyor and How Does It Work?
In a tube screw conveyor, a screw flight driven by a motor-gearbox unit pushes the product along a fully enclosed tube. Product taken in at the inlet travels inside the tube and is discharged at the outlet into the target equipment. The closed cross-section protects the product from external influences and allows controlled conveying even on inclined or vertical runs.
Key Features
- Dust-free, loss-free conveying in a closed tube body
- Suitable for horizontal, inclined and vertical runs
- Available in different diameters, lengths and capacities
- Galvanised or painted body options for long service life
Applications
- Silo discharge and filling lines
- Machine feeding in feed and flour mills
- Mobile and fixed product transfer applications
- Truck and trailer loading points
Integration with Plant and Automation Systems
The tube screw conveyor connects directly to silo gates, hoppers, bucket elevators and weighing units. Its motor control is wired to the automation panel so it starts and stops in sequence with the rest of the line.
Engineering and Selecting the Right Product
The type and flowability of the product, line length, angle of incline and target capacity determine the tube diameter, screw pitch and motor power. The capacity drop on steep inclines is taken into account at the engineering stage.
Frequently Asked Questions
It can be used from horizontal lines up to vertical applications; because capacity decreases as the incline increases, the unit is sized accordingly.
The tube screw conveyor suits dust-free and inclined conveying thanks to its closed tube body, while the U-trough type with its removable covers suits horizontal lines that need maintenance access.
