Abstract
An apparatus to effect optimum delivery of dry bulk material from a hopper includes a device to provide vibratory stimulus to the hopper. The device for providing vibratory stimulus includes a device to identify the resonant frequency of the hopper and its contents at any time and to automatically continuously vary the frequency of the vibratory stimulus to maintain this frequency at, or close to, the resonant frequency of the hopper and its contents.

An apparatus for effecting optimum delivery of dry bulk material from a hopper, comprising:
- means for providing vibratory stimulus to a hopper;
- means for identifying a resonant frequency of the hopper and contents of the hopper;
- and,
- means for automatically continuously varying a frequency of the vibratory stimulus for maintaining said frequency of the vibratory stimulus at, or close to, the resonant frequency of the hopper and its contents.
A method for effecting optimum delivery of dry bulk material from a hopper, comprising the steps of:
- providing vibratory stimulus to a hopper;
- identifying a resonant frequency of the hopper and contents of the hopper;
- and,
- continuously varying a frequency of the vibratory stimulus to the hopper for maintaining the frequency of the vibratory stimulus to the hopper at, or close to, the resonant frequency of the hopper and the contents of the hopper.
