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 assembly via a V-belt transmission. The speed of the screen (frequency ...
