The Brabender Bin Activator "BAV" is a vibratory discharge aid ensuring a constant bulk solids flow even in case of poor flowing bulk ingredients and if silo diameters are large but outlet cross sections are small.
The bin activator consists of a discharge cone with an integrated baffle support, which is supended from a silo-welded flat ring by horizontally flexible hanger arms. An unbalance motor generates a horizontal circular vibration of the suspended part and induces active mass flow of the bulk solids and reliable discharge through the annular gap between the silo cone and the baffle support, which carries the bulk material column, thus relieves the outlet and prevents block-ups.
The highly flexible, seamless PUR transition sleeve between the flat ring and the discharge cone ensures optimum vibration isolation from the silo.
The dust-tight transition sleeve between the flat ring and the discharge cone is secured by a safety connection offering high overpressure and underpressure proofness already with the standard version. In addition, the high flexibility of the sleeve material ensures optimum vibration isolation from the silo and reduces the undesired transmission of vibration into the silo to almost none. The sleeve is made of endless polyurethane without seams.
Bin activator models available cover diameters from 600 to 1800 mm, thus offering suitable units for bins ranging from small-size hoppers to large silos, which may be made of mild steel, stainless steel, aluminium or plastics.
The Brabender Bin Activator "BAV" can be supplied made of of either mild or stainless steel. Explosion-proof versions are available.
