Hopper with horizontal extraction screw conveyor

Hopper with Horizontal extraction screw conveyor, 6 m3 volume designed and manufactured by BEMA. The extraction screw are only used to empty the hopper. It you combine a horizontal extraction screw together with a hopper, you can use the extraction screw as a dosing screw conveyor. The hopper with the extraction screw conveyor is design completely with supports ready to be put in place at the customer site. The support of the hopper is delivered with reinforcement plates take up the material pressure from the material inside the hopper. The hopper is delivered as a complete machine

What to clarify when you need a hopper with an extraction screw conveyor

1. Define the size of the hopper
2. Describe the material and ensure that it is suitable for screw conveyor transport
3. Define the flowrate in which you want to take the material out of the hopper

With this information BEMA can propose a design suitable for the actual application. See another example of a BEMA hopper with an extraction auger here. Hoppers in combination with a screw conveyor makes it possible to close the transport solution completely. This is relevant in the cases where you want to avoid emissions to the external environment. Compared to other solutions this is a very clear advantage in using a screw conveyor. Designing hoppers in combination with screw conveyors require engineering capabilities. In BEMA we can support you in this process and ensure you get a good and well workable solution. When contacting BEMA, kindly send us the above required informations, and we shall give you an appropriate answer.

FAQ: Hopper with horizontal extraction screw conveyor

1. What is a hopper with a horizontal extraction screw conveyor?

A hopper with a horizontal extraction screw conveyor is a complete bulk‑handling solution designed to store materials and extract them efficiently using a horizontally mounted screw. The extraction screw’s primary purpose is to empty the hopper, but when combined as a system, it can also function as a dosing screw conveyor, enabling controlled and consistent material flow.

2. What are the key benefits of this hopper‑and‑screw configuration?

This solution allows the transport system to be fully enclosed, which is especially valuable when emissions to the external environment must be avoided. Compared to open or semi‑open alternatives, the screw conveyor provides a cleaner, safer, and more controlled handling method for powders, granulates, and other bulk materials.

3. What information is required to design the correct hopper solution?

To ensure the hopper is engineered correctly, BEMA needs three essential details:

• The required hopper size
• A description of the material and confirmation that it is suitable for screw transport
• The desired flow rate for material extraction With this information, BEMA can propose a design tailored to the specific application.

4. How is the hopper constructed?

The hopper is delivered as a complete machine, including support structures with reinforcement plates designed to withstand internal material pressure. It arrives ready for installation at the customer’s site, ensuring a smooth and efficient setup process.

5. When is this type of hopper the ideal choice?

This solution is ideal when controlled dosing, enclosed transport, and reliable material extraction are required—particularly in industries where environmental protection and engineered flow control are critical.
