Vibra Screw heavy-duty bin dischargers for large silos combine a shallow upper section with a steeper lower cone; the compound shape eliminates bridging and packing at the discharge outlet, as well as the need for secondary baffles. The dischargers are available in diameters from 7 to 12 ft. and in carbon and stainless steel.
