Bin activators “BAV” from Brabender Technologie are vibratory discharge bottoms for silos and bins and are indispensable wherever difficult to handle bulk materials have to be discharged. Particularly if silo diameters are large but outlet cross sections are small, dry solids with flow characteristics from poorly flowing to floodable and with particle sizes from fine to coarse are discharged in an equally dependable manner. The working principle (vibrating discharge cone with intergrated baffle support supended from a silo-welded flat ring by horizontally flexible hanger arms) promotes uniform mass flow and first in – first out discharge without bridging, ratholing, material compaction or particle deterioration. The product line includes models with diameters from 600 to 3000 mm for small-size bins to huge silos. Brabender bin activators are available made of mild steel or stainless steel. Options include pressure-resistant, temperature-resistant and explosion-proof versions.
