ABSTRACT:
An aerating or fluidizing device is located adjacent the gravity discharge opening of a hopper. The device is in the form of a flexible, resilient member fixed so that a marginal edge normally contacts and defines an interface with an associated surface. Air under pressure is fed to the interface in such fashion as to cause the marginal edge of the resilient member to flutter and allow the air to escape in randomly directed "puffs." The fluttering movement combined with the intermittent puffs of air causes pulverulent material to be agitated, aerated and/or fluidized as it passes to the discharge opening.
