In this research work, after allowing the experiment to run, we proved the possibility to dose sand in the sand feeding system with the effect of vibratory displacement. We set the disturbing frequency and amplitude, at which the maximum system performance is achieved. The sand consumption curves were obtained depending on the oscillation frequency, pulse shape, and tilt angle. A model proposed to describe the effect of vibrodisplacement in a sand feeding system. It was established that disturbances cause sand oscillations at multitude frequencies, coinciding with which resonance phenomena occur. In practice, it means the increase in consumption.
