Vibration Aerators combine the injection of compressed air (working pressure up to 6 bar) and the generation of light vibrations on the silo wall. They represent a gentle alternative to the application of a compressed air hammer or compressed air interval tapper, as they have a considerably lower structural load. Existing silos can be easily converted to Vibration Aerators. For particularly high demands, the VBSI version is equipped with a stainless steel shaft. Our Vibration Aerators have FDA approval and are therefore approved for use with foodstuffs.
Vibration Aerators are used for material flow improvement and aeration of powders and granules. They combine material aeration with additional light vibrations of the silo wall and are a gentle alternative to compressed air knockers and pneumatic hammers, as they have a considerably lower structural load.
Installation of the Vibration Aerators is relatively simple. A hole is drilled in the wall of the silo or hopper, the Vibration Aerator is pushed through, tightened with a nut, and the compressed air supply is connected. Done!
Compressed air is discharged directly into the material via the silicone lip that rests against the inner wall of the silo. A variation of the working pressure changes the vibration strength of the silicone lip. Due to clocked operation and the maximum required working time of 5 seconds, the air consumption is extremely low.
Due to the design, damage to the silo wall is excluded even with abrasive products. The Vibration Aerators have a robust design and are self-cleaning. Additional non-return valves are not required, as the working pressure (2 to 6 bar) means that no product can get under the supple silicone lip. This is made of a silicone rubber that complies with BfR and FDA regulations for contact with food. Thus, its use in the food sector is permissible.
Products successfully tested with VBS: Cement, sand, lime, calcium carbonate, sugar, flour, additives, diatomaceous earth, talc, filler, dolomite, soda ash, feldspar, pellets, limestone, stoneware atomized, etc.
For special requirements a version with stainless steel shaft (type VBSI), a metal detectable version (type VBSI-MD), a miniature version for small hoppers and radii (type VBSM/VBSMI) as well as a version for external mounting (type VBE) are available.
Field of application
The Vibration Aerators are suitable for the following applications:
- Emptying aid for containers
- Maintaining material flow and releasing product jams
The Vibration Aerators are operated with 2 to 6 bar compressed air. The frequency of vibration can be increased/decreased by throttling the air supply.
The operating temperature is -40°C to +170°C.
