Pneumatic vibrators
BRECON High Frequency External Vibrators are the right choice for wet-cast compaction and specific requirements.
BRECON high frequency vibrators generate amplitudes from 6.000 r.p.m. for standard wet-cast applications and up to 9.000-12.000 r.p.m. for specific requirements like e.g. in large concrete pipe forms.Wet cast concrete only consolidates at frequencies between 4.500 and 6000rpm with a proper quality. Just the right frequency guarantees a perfect compaction without the risk of disaggregation. With a variable drive it is possible to determine the optimum frequency where the concrete consolidates in shortest time and with highest density.
The ideal frequency for each mixture can be adjusted by frequency inverters that are indispensible for operating high frequency vibrators. The highest quality can be reached with our Synchronous External Vibrators.

Possible applications for BRECON
pneumatic external vibrators:
Dry Cast Concrete
Dry cast concrete compaction is a extreme rough applications, ideal for BRECON high quality vibrators to unfold their full potential and high reliability.
Wet cast concrete compacting
Wet cast concrete offers through its liquidity an enormous flexibility, being suitable for realizing almost any kind of elements. Due to this, pre-cast plants using wet cast concrete have to adapt the compaction constantly to new elements, designs and sizes, usually in small custom-made series.
Loosening and breaking up
BRECON external vibrators are also used for the collapse of bulk material arches in silos or other containers in which the bulk materials (e.g. sand, lime, cement, coal, cereals etc.) are kept before her further processing. The friction between the material particles is reduced by the vibration caused by the external vibrator and the adhesive forces between silo wall and bulk material are overcome. There are two kinds of bulk material arches: Bridge and shaft formation.
