Ore, Rock & Aggregate Screening (Complete Guide)
Screens with a circular motion are the most common type. The vibration is circular because of a single eccentric shaft mechanism. This movement would not move the material forward, unless the screen is inclined in the direction of the material flow. This in turn means that the screening efficiency is not quite as good as a horizontal screen.

Eccentric (mechanism)
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 center). [1] Eccentric sheave, with strap and eccentric rod fitted. It is used most often in steam engines, and used to convert rotary motion into linear reciprocating motion to drive a sliding …

Screening Machines Comparison
The eccentric vibrating screen relies on the high-speed rotation of the eccentric drive shaft to make the screen vibrate, so it is called the eccentric vibrating screen. The eccentric shaft directly drives the screen frame to make a trajectory movement in the vertical plane with an amplitude equivalent to twice the eccentricity.
