IAC - Vibrating Hoppers

These are one of the most important and versatile flow assisters.  They are used to enlarge the storage bin opening and to cause flow by breaking up material bridges.  Two basic types of vibrating hoppers are common: the gyrating kind, in which vibration is applied perpendicularly to the flow channel, and the whirlpool type, which by providing a combined twist and lift to the material, causes bridging to break.
