Vibra-Jet™ Bin Aerator Model K Series 683

Vibra-Jet™ Bin Aerator
Model K Series 683

Restores material flowability at low cost

The Model K Vibra-Jet bin aerator, when installed on any storage silo, bin or hopper, can be extremely versatile and effective in getting dry bulk materials, like fine cement, to gravity feed more reliably at a very low cost. Materials which tend to pack, bridge or hang up can be made to flow freely and instantly upon demand.

Balances the natural negative pressures during discharge

Model K Vibra-Jet bin aerators installed at strategic locations on a discharge cone of a storage silo, bin or hopper direct high or low pressure compressed air along the bin wall to reduce the coefficient of friction which exists between the bin wall and the stored material. The compressed air, which is injected in short high-pressure bursts, fully balances the natural negative pressures created during the normal discharge process. By controlling the compressed air pressure and volume, materials once thought to be difficult to handle now gravity feed easily, quickly and automatically.

Maximizes performance and energy

Because every material is unique to itself, the Model K Vibra-Jet bin aerator has the extreme flexibility to throttle the compressed air as required to handle almost any dry bulk solid material which is finer than 20 mesh (800 micron), regardless of its bulk density. This feature also maximizes process performance and minimizes the compressed air demand, plus it reduces the overall energy requirements.

Three seals extend life and reliability

Some unique construction features have been designed into the Model K Vibra-Jet bin aerator to prevent backfeeding and truly set it apart from all other types of bin aerators available. This is extremely important because as the very fine dry bulk materials become fluidized and more flowable they can, under certain circumstances, backfeed into the air source. To prevent this from happening, the Model K Vibra-Jet bin aerator has incorporated three seals. A primary seal at the outer edge and a secondary seal next to it provide an almost impermeable wall to prevent material from trying to backfeed under the gasket. Then, a third and final seal backs up the other two to provide additional assurance against possible backfeeding, even under the most severe of applications. This provides added reliability and extends the life dramatically.
