Each source of noise and vibration is described in a systematic way rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration.Exciter Mechanisms Vibration Types. Exciters are the main vibration source of the screens. They generally comprise a housing, bearing, shaft and an eccentric mass. The vibration results from the rotation of the eccentric mass about the exciter shaft. Generally, power is transmitted from the drive motor to the vibrator assembly via a V-belt.

Cam and follower is used to give to and fro motion for vibrating screen. Vibrating screen performance has steadily improved by using multiple level screens. Lots of vibrating screening system developed recently. Some systems like eccentric shaft, slider crank mechanism, centrifugal mechanisms.Noise is defined as any loud, discordant or disagreeable sound or sounds. commonly, in an environmental context, noise is defined simply as unwanted sound. Certain activities inherently produce sound levels or sound characteristics that have the potential to create noise. The sound generated by proposed or existing facilities may become.
