ABSTRACT:
Apparatus for enhancing the feeding of particles includes a hopper having a central axis, walls of the hopper being concentric with the hopper axis above an outlet of the hopper; a sensor for sensing a desired flow of particles from the hopper; a shaft rotatably mounted on the hopper axis; a paddle connected to the shaft and extending from approximately 0.125 inch to approximately 0.250 inch from at least a lower portion of an inside surface wall of the hopper, the shaft being rotated at approximately 1 radian per second in response to a drive signal; the drive signal being momentarily activated in the presence of an external activate signal when the flow of particles falls below the desired rate, the drive signal being active for a period of time sufficient to cause the paddle to move through an angle of about 90.degree. about the hopper axis. The paddle is mechanically agitated during feeding of the particles, the paddle vibrating only during activation of the external signal, with a displacement of from 0.01 inch to 0.1 inch when contacting the particles.
