ABSTRACT:
An upper hopper is adapted to receive bulk material. A lower hopper is disposed under said upper hopper and adapted to receive bulk material from the upper hopper and to deliver said bulk material. A substantially cylindrical, rigid connecting ring is disposed between and resiliently connected to said upper and lower hoppers and defines a flow path between them. A plurality of blades which are angularly spaced apart in a horizontal plane are supported by said connecting ring at fixed points thereof and extend substantially radially in said flow path. At least two vibration machines are mounted on said connecting ring and operable in the same sense of rotation to impart sinusoidally varying, angular oscillations to said connecting ring.
