Vibrating Screen Working Principle

Near each end of the shaft, an eccentric portion is turned. The shaft is counterbalanced, by weighted flywheels, against the weight of the screen and loads that may be superimposed on it. When the shaft rotates, eccentric motion is transmitted from the eccentric portions, through the two bearings, to

Eccentric (mechanism) Wikipedia

In mechanical engineering, an eccentric is a circular disk (eccentric sheave) solidly fixed to a rotating axle with its centre offset from that of the axle (hence the word "eccentric" out of the centre). It is used most often in steam engines, and used to convert rotary into linear reciproing motion to drive a sliding valve or pump ram.
