Dosing screw conveyor powder distribution system

Complete system for transport and distribution of powder from big-bags in an offshore application. The dosing screw conveyor delivers material to a number of following transporttion screw conveyors.

How shall I design the a system of dosing screw conveyor followed by transportion screws?

1. Be sure that the dosing screw rotor is 100% filled during the operation
2. Design the dosing screw conveyor to cover the full range of material flow you need
3. Design the following screw conveyors with a higher capacity compared to the dosing screw conveyor. The more speed you can give the transportion screw conveyors, the lower filling degree and a more smooth delivery of material to the final destination

Can I control the material flow in a dosing screw conveyor precisely?

1. Yes, but you must know the density of the transported material precisely.
2. Always have in mind that a screw rotor moves a volume, and the density is needed to calculate the material flow

Special features in the actual project

• Complete delivery with full documentation (drawings, material certificates and test run certificates)
• System FAT approved before delivery

FAQ – Dosing Screw Conveyor Powder Distribution System

1. Purpose of a dosing screw conveyor system

A dosing screw conveyor system is designed to transport and distribute powder from big bags in demanding environments such as offshore installations. The dosing screw ensures a stable and controlled feed to the following transport screw conveyors, creating a smooth and reliable material flow through the entire process.

2. How to design an efficient dosing and transport setup

For optimal performance, the dosing screw must operate at a 100% filling degree. It should be dimensioned to cover the full required flow range, while the following transport screws must be designed with higher capacity. Higher speed in the transport screws results in a lower filling degree and a more stable delivery to the final destination.

3. How precisely the material flow can be controlled

Precise flow control is possible, but only when the density of the powder is known accurately. A screw conveyor moves a fixed volume, so the density is essential for calculating the actual mass flow. Correct material data is therefore crucial for achieving accurate dosing performance.

4. Key advantages of the system

The system is delivered with full documentation, including drawings, material certificates and test‑run certificates. It is FAT‑approved before shipment, and BEMA’s extensive experience with combined dosing and transport systems ensures high reliability and excellent handling of powder and powder‑like materials. BEMA has the experience to design systems where you combine dosing followed by transportation of the material. Specially powder and powder liked material are well suited for this transportation process.
