Project with 2 pcs. 3 m3 silos with extraction screw conveyors.
The screw conveyor with storage bin manufactured in carbon steel is used as an intermediate storage for recycled parts. The stainless steel bin with screw conveyor is acting as a classifier – The screw conveyor takes slowely parts out of the bin after they have bin cleaned by the water in the tank. A double horizontal screw conveyor is a part of the project for further transport of the waste material The solution is manufactured for a cable recycling plant, where the different crushed cables are sorted into specific fractions. The screw conveyor with bins are part of the internal sort and transportation. The screw conveyor is bolted to bin via a flange connection. This makes it more efficient to transport over long distances.
The design of a storage bin with a screw conveyor really depends on the actual application.
Before contacting BEMA we recommend that you consider these questions and make a small sketch for us. This will make the design phase much more efficient, and ensures that the main details of the solution have been clarified from the beginning.

The conveyor is flange‑mounted directly to the bin, creating a sealed and stable connection that supports efficient material extraction and enables transport over longer distances without leakage or dust issues.
The solution can be built in carbon steel or stainless steel (e.g., 1.4301) depending on the application. Stainless steel is used when the bin contains water or requires corrosion resistance, such as when functioning as a clarifier or classifier.
Key parameters include bin size, filling method, support structure, transport optimization, material friction (risk of bridging), discharge point, and the required emptying rate of the screw conveyor. These factors define the geometry and mechanical configuration.
It provides controlled and continuous material flow, minimal moving parts, low maintenance needs, and a fully enclosed transport path that reduces dust and environmental impact. It is especially effective for internal sorting and waste‑material handling in recycling processes.
