This paper presents the problems encountered in the suppression of vibration in machines with a low degree of rigidity, especially when the vibration is to be suppressed in only part of a facility, as the oscillatory motion of the remaining equipment in the team is its normal working movement. An example of such a device is a vibrating sifter, this being a machine with a percussive (shock) way of operating. The nature of vibrations in this type of equipment depends on the foundation’s rigidity as well as the rigidity of the screen itself. Both may undergo change during operation of the machine, due to cracking of structural elements as a result of the impact of the force causing the movement of the screened material.
