Bin with lifting screw conveyor
Bin with lifting screw conveyor
Bin with lifting screw conveyor – 3 m3 bin with a Ø135 mm lifting screw conveyor. The screw conveyor acts primarely as an extraction screw conveyor for the bin. In this particular case, the bin is manufactured as an inverted pyramid. The inlet to the screw conveyor has a quite small area, which avoid blocking of the screw conveyor. Such a solution is only working well if the material flows easily.
What is the advantages of a bin with an extraction screw conveyor?
- You get the material out of the bin and lifted to the required height in one process.
- The screw conveyor can lift the material in a steep angle
- When you use a screw conveyor you can close the hole system and avoid emissions
Design of a bin with lifting screw conveyor depends strongly on the actual situation. It also depends on the material you put in the bin. In this case it must be easy flowing – otherwise there is a risk of bridge building with the selected design of the bin. The connection to the bin goes via a flange connection in the bottom of the bin. This makes it easy to uninstall the screw conveyor. This design has been done in cooperation with the customer who ships the solution all over the world.
Summing up on this solution, it has the following key points:
- It is used for storage and lifting of the material
- The inlet to the screw conveyor has a small area which require a smaller gear box
- The screw conveyor is easy to uninstall for easier transportation

FAQ – Bin with Lifting Screw Conveyor
1. What is a bin with a lifting transportation screw used for
A bin with a lifting screw conveyor is designed for both storage and vertical transport of material in one integrated process. The screw acts primarily as an extraction conveyor, pulling material from the bottom of the bin and lifting it to the required height. This makes the solution ideal for easy‑flowing materials that need controlled discharge and elevation.
2. Why is the inlet design important for performance
The inlet area to the screw conveyor is intentionally small to prevent blocking. This design works effectively only when the material flows easily, as poor‑flowing media may cause bridge building in the inverted pyramid‑shaped bin. The small inlet also allows the use of a smaller gearbox, reducing energy consumption.
3. What are the advantages of combining storage and lifting in one unit
The system enables material extraction and lifting in a single step, supports steep conveying angles and allows the entire setup to be closed to avoid emissions. This reduces the need for additional equipment and creates a compact, efficient and clean material‑handling solution.
4. How is the system designed for easy installation and maintenance
The screw conveyor is connected via a bottom flange, making it easy to uninstall for service or global transport. The design is developed in close cooperation with the customer, ensuring flexibility and straightforward installation across different sites and applications.
