Vibratory Movement of the Friable Material in the Conditions of Combined Vibrations of the Working Member

The reasons of occurrence of non-working fluctuations in the vibratory machine are considered. The mathematical model of movement of the loaded resonant vibratory feeder is worked out and by means of mathematical modelling is shown influence of spatial non-working fluctuations on the character of the vibratory movement of the material. It is shown, that the combination of some non-working fluctuations with working resonant fluctuations an increase of speed and intensity of movement of the material is reached which is a constructionally realizable problem.
