Bunkers with Filling capacity from 5 to 750 litres
Storage and dosing bunkers are used to store large quantities of bulk material and feed it in a metered manner to a downstream vibrating conveyor.
With FMB storage bunkers, the autonomy of a system can be increased many times over.
As a specialist in the field of vibration technology, we develop storage bunkers either as individual components for integration into customer systems, or complete feeding solutions with integrated bulk material storage and material dosing.
Depending on the size and weight of the material to be conveyed, the desired storage volume, and the dosing behavior of the workpieces, our storage bunkers can be designed in different sizes and drive concepts.
Drive variants of our storage and dosing bunkers
Vibration bunker with micro-throw technology:
The storage and dosing bunkers in sizes BVB-5 to BVB-150 are driven by our linear vibratory drives of type BSR and thus work in the same way as linear vibratory conveyors on the micro-throw principle.
This means that the material being conveyed is repeatedly conveyed a little further during the conveying process and in doing so performs a micro-throw movement.
Vibration bunkers with micro-throw technology are standard systems on the market.
Vibration bunker with sliding conveyor technology:
The low-frequency drive of the storage and dosing bunkers BVB-300 to BVB-750 is special because it works using the sliding conveying method.
This means that the material to be conveyed no longer lifts off the conveyor surface of the bunker trough during the conveying process, but instead slides forward very quietly. Since the acceleration due to gravity is not exceeded by the system, it is an absolutely low-noise and gentle method of vibratory conveying of mass parts.
FMB's vibrating bunkers with sliding conveyor technology are unique on the market!
Advantages of the FMB storage bunker with sliding conveyor technology:
- Effective filling capacity of up to 750 litres
- Load weight of up to 2,000 kg
- Special control electronics for maintaining a constant conveying speed even with large differences in load weight
- Very low noise level even in continuous operation
- Gentle conveying of sensitive workpieces
- Extremely low wear levels due to tough polyurethane coating
- Energy-savings due to automatic power control

Vibrating hopper
A vibrating hopper essentially comprises the following components:
- Vibratory drive (micro-ejection or low-frequency feeder technology)
- Control unit (phase control device or control electronics)
- Hopper bowl 5 to 750 litres
- Coating (according to goods to be conveyed)
- Base
Belt conveyor hopper
A belt conveyor hopper essentially comprises the following components:
- Drive powered by electric motor
- Transport belt
- Hopper bowl 5 to 750 litres
- Base
Depending on the size of the bunker and the loading weight, different drive sizes and drive concepts are used to drive our vibrating bunkers:
- Storage and dosing bunker type BVB-5 to BVB-50:
Linear oscillating drive type BSR-2 with micro-throw technology - Storage and dosing bunker type BVB-50 to BVB-150:
Linear oscillating drive type BSR-3 with micro-throw technology - Storage and dosing bunker type BVB-300 to BVB-750:
Low-frequency drive type BBR-12/4 with sliding conveyor technology
For belt bunkers / inclined belt bunkers of types BB/SBB, either three-phase or direct current gear motors are used.
Appropriate control units are required for regulating the linear vibrating drives of the storage hoppers. They can be used to adjust the conveying speed and in many cases have a cut-off switch activated by filling level. Depending on the size of the storage hopper, we employ tried and tested techniques, with either phase control or frequency control units.
The hopper bowls come in standard sizes and have a sturdy welded construction. Their production and coating depends on the application in hand. Hopper bowls for the pharmaceutical sector are made of stainless steel type 1.4404 and can be supplied with a finish produced by glass-bead blasting or electrolytic polishing.
The coating of the hopper bowls matches the material to be conveyed and not only reduces noise but also prevents wear and protects the material being conveyed. In most cases, the coating material is polyurethane in thicknesses ranging from 3 – 10 mm.
