In practice, these devices have been in use for over 100 years in the market, showcasing their enduring significance [17]. The driving mechanism is crucial for a variety of material processing industries, such as mining and quarrying. Essentially, most vibrating screens operate with a shaft that has two eccentric masses attached, one on each side.

The main feature of the Vibrating Screen is the patented mechanism. In operation, the screen shaft rotates on two eccentrically mounted bearings, and this eccentric motion is transmitted into the screen body, causing a true circular throw motion, the radius of which is equivalent to the radius of eccentricity on the eccentric portion of the shaft.
