Conveying and dosing systems
1. Mechanical conveying and dosing systems
Different raw materials require different conveying and dosing methods. We offer a wide range of conveying and dosing systems to ensure maximum flexibility.
We always design the required conveying and dosing systems specifically for your raw material. This way, you can be sure that conveying and dosing is guaranteed, even under the most diverse influences, such as seasonal changes (warm/cold).
MECHANICAL DOSING SYSTEMS
Screw Conveyors/Dosing Screws & Vibrating Feeders
Technical Specifications:
| Execution | Tubular screw or trough screw |
|---|---|
| material | Stainless steel, normal steel, aluminum or plastic |
| diameter | 30mm – 500mm |
| Pressure shock resistant | up to 10 bar overpressure possible |
ATEX: All screws can be manufactured to ATEX standards upon request, e.g., for Zone 20/21 (custom designs available).
Compactor screws:
Special shapes – Compactor screw (example)
The product can be compacted during transport/dosing.
Cooling Screws
Special Shapes – Cooling Screw
(Example)
The product can be cooled/heated during transport/dosing.
Conveyor Belts/Dosing Belts
Technical Specifications:

2. Pneumatic conveying and dosing systems
A suction or pressure conveying system is often the better/more cost-effective solution for conveying or dosing products from A to B. These systems can also be used as dosing systems. Here, comparable accuracy values can be achieved as with a conventional dosing system.
Technical data:
| Ausführung | Suction conveying or pressure conveying |
|---|---|
| material | Stainless steel, normal steel, PE or RUBBER |
| Performance | 10kg/h to 20t/h |
| Conveyor path | 1m to 300m, depending on the product |
Suction scales
With a suction scale, products can be conveyed and metered simultaneously.
This is a space-saving and flexible solution for feeding raw materials, for example, into a mixing process.

3. Dense phase conveying
FÖRDER_DYNAMIC Schüttgutanlagentechnik GmbH is a separate division of B&K, which specializes in pneumatic dense-phase conveying for a wide variety of products. Dense-phase conveying is a pneumatic conveying principle used to transport large quantities of raw materials from point A to point B while handling them as gently as possible.

Conveyor Conveying:
Filling of the conveyor is initiated by opening the filling and venting flap. The conveyor fills quickly, as the displacement air can escape unhindered through the separate venting opening. Once the filling level is reached (level switch), both flaps close again, with limit switches monitoring the precise closing position. The conveyor is pressurized with compressed air, and the material is forced into the conveyor at the highest possible density, thus achieving a highly economical conveying process. After conveying is complete, the air pressure drops, and the supply air is automatically shut off. The conveyor is now ready for the next conveying cycle.
To achieve higher capacities, conveying can also be carried out via a high-pressure rotary valve.
Testing Center
To test product destruction or conveying performance of your products, B&K has its own in-house test facility with a conveying length of approximately 110m. This can be tested both as a conveyor system and as a rotary valve system.
Contact our team to arrange a possible product trial at our facility.
Sender Design
Each standard sender can be designed or customized to meet even the most challenging conveying requirements. The sender containers are also available in various materials and oversized sizes upon request.
