Vibrating Grizzly Feeder works on the phenomena of Vibration. Here vibration means "to move back and forth rapidly." On a vibratory feeder, material is "thrown" up and forward so that it drops to the surface at a point further down the tray. This is the feeder's amplitude. The number of times per minute that it repeats is the frequency.

Where VRmax (=Vmax,OFF / Vmax,ON) is a conservative measure of the increase in the maximum feeders' vibration velocity considering the Off/On-bearing configurations. It is noted that the effect of the Off-bearing operation on the allowable feeder vibration velocities (left hand side of the velocity criterion) will be handled in a separate paper.
These components can be revealed by plotting vibration amplitude against frequency. The breaking down of vibra- tion signals into individual frequency components is called frequency analysis, a technique which may be con- sidered the cornerstone of diagnostic vibration measure- ments.
