Bin with swivel screw conveyor

Bin with swivel screw conveyor manufactured to store drill cuttings for distribution to transport containers. The bin is a part of a complete transport system:

• Storing the cuttings intermediately
• Further delivery to transport containers
• Transport containers to be taken on-shore for further treatment

Main challenge in the project

1. Design of the swivel screw
2. Finding a soluton for safe handling when the swivel screw is turned
3. Finding a solution for combining the swivel screw with the bin

The swivel screw conveyor is inclined. To feed the swivel screw it is necessary to have a horizontal screw conveyor in the bottom of the bin. The swivel screw conveyor is supported in a single vertical point in which it can turn app. 120°. In this solution the bin has 3 different functions:

1. Storage of material
2. emptying to the swivel screw via a horizontal screw conveyor
3. Inclined transport to transport containers in different positions

All functions are solved by 3 independant components:

• The bin
• The horizontal extraction screw conveyor
• The inclined swivel screw

The independant components ensure a failure proof and very reliable solution. See another example of a swivel screw conveyor here. Bin design in combination with screw conveyors require skilled engineering to be succesfull. BEMA has engineering expertice to assist in the initial design phase. We recommend that you contact BEMA as soon as possible when the project is under planning. BEMA has solved different projects with swivel screw conveyors which you can find here on our web-site.

FAQ: Bin with swivel screw conveyor

1. Purpose of a bin with swivel screw conveyor

A bin with a swivel screw conveyor is designed to store drill cuttings and distribute them efficiently to transport containers. It forms part of a complete handling system where cuttings are stored temporarily, transferred safely and then transported onshore for further treatment. The solution ensures controlled flow and reliable material handling.

2. Main challenges addressed by the design

The system solves several engineering challenges: designing a swivel screw that can rotate safely, ensuring stable feeding when the screw is turned and integrating the swivel screw with the bin. These challenges are handled through a combination of horizontal and inclined screw conveyors that work together seamlessly.

3. How the system operates

The swivel screw conveyor is inclined and therefore requires a horizontal extraction screw at the bottom of the bin to feed it consistently. The swivel screw is supported at a single vertical point, allowing it to rotate approximately 120°, enabling discharge into containers positioned at different locations. This provides flexibility and operational efficiency.

4. Benefits of using independent components

The system consists of three independent components: the bin, the horizontal extraction screw and the inclined swivel screw. This modular approach ensures a failure‑proof and highly reliable solution, as each component can operate and be serviced independently without compromising the overall system.

5. BEMA’s engineering expertise

Successful bin and screw conveyor integration requires skilled engineering. BEMA provides expert assistance in the early design phase to ensure correct dimensioning, safe operation and optimal performance. Their experience with multiple swivel screw projects ensures a well‑engineered and proven solution.
