Abstract
A volumetric dry solids materials feeder comprises a supply hopper, a feed trough disposed below the hopper, and an auger disposed in the feed trough to feed out the material. The trough is anchored to a vibration base, on which is mounted a vibratory mechanism. A vibration transfer spring connects the vibration base to a bracket secured to the hopper. Upon activation, the vibratory mechanism vibrates the vibration base and thus the trough at a predetermined frequency, while the spring transfers the vibration to the hopper. The spring lessens the amplitude of the transferred vibration and changes the frequency thereof, so as to minimize interference (primarily harmonic problems) between the vibration of the hopper and trough.
