Bin with horizontal screw conveyor

Bin with horizontal screw conveyor manufactured for recycled material. The size of the bin is approximately 12 m3 with screw a horizontal screw rotor in the bottom. When designing this type of bin, it is important that the material do not bridring. If there is a risk of bridging you shall look for live screw bottoom – see an example here.

Advantage of having a horizontal screw conveyor in the bottom of the bin

• The screw conveyor can be used as a dosing screw rotor
• By adding a frequency inverter to the electrical motor, you can control the output

In the actual case the bin acts as a plain storage for recycled material. It is emptied when it is filled checked manually by the production employoees.

What to consider when designing the bin?

1. The size of the bin
2. The rate in which you want to empty it
3. The flowability of the product
4. The abrasivity of the product

In this case BEMA has manufactured the screw rotor with HARDOX screw flights. This increases the lifte time of the screw rotor, if the material is abrasive. Other examples of a hopper with a horizontal screw conveyor BEMA has many years of experience in designing bins with screw conveyors. A good design requires respect for the engineering, because there are more parameters to take into consideration. We recommend you to contact BEMA as early as possible in the desing process to get the best possible result.

FAQ – Bin with Horizontal Screw Conveyor

1. What is the purpose of a bin with a horizontal screw conveyor

This type of bin is designed for storing and discharging recycled materials efficiently. The horizontal screw rotor at the bottom ensures controlled emptying and can function as a dosing screw when combined with a frequency inverter for adjustable output.

2. When is a horizontal screw conveyor the right choice

A horizontal screw is ideal when the material flows easily and does not tend to bridge. If bridging is likely, a live screw bottom is recommended instead. The solution is well‑suited for applications where stable discharge and predictable flow are required.

3. What factors must be considered during design

Key considerations include bin size, desired emptying rate, material flowability and abrasiveness. These parameters determine the screw dimensions, motor setup and whether special materials or reinforcements are needed. Proper engineering ensures long‑term reliability and efficient operation.

4. How durability is ensured for abrasive recycled materials

For abrasive products, BEMA manufactures the screw rotor with HARDOX flights to extend service life. This significantly increases wear resistance and reduces maintenance needs, making the system suitable for demanding recycling environments.

5. Why involve BEMA early in the project

Designing bins with screw conveyors requires careful engineering, as multiple parameters influence performance. BEMA’s long experience ensures that each solution is tailored to the material, capacity and installation conditions. Early dialogue helps secure the best technical and practical result.
