To strengthen the screening efficiency of traditional vibrating screens, a new type of vibrating screen, namely the composite vibrating screen, has been proposed based on the Lissajous vibration synthesis theory. The working principles of composite vibrating screens have been explained. Numerical simulations of the sieving processes for such composite vibrating …

This motion creates extremely high levels of vibration, but only at a specific frequency. This is known as the operating or shaking frequency.

Sommerfeld effect of first kind occurs in various kinds of other systems, such as rotor dynamic system [12–15], slider crank mechanism [16], cam-follower and Scotch yoke mechanisms [17,18], cart-pendulum system, portal frame and stick-slip motion on conveyor belts [19], nano-scale dynamic visco-elastic absorber and nonlinear electromechanical ...
by the eccentric mechanisms and the gears used to drive them. Each eccentric mechanism uses two rotating un balanced shafts that are supported on two bearings each. One shaft of the irst eccentric mechanism is driven by an electric motor by a belt. This shaft is directly coupled to one of the shafts in the second eccentric mechanism.The
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.
Vibrating mechanism includes heavy duty eccentric shafts rotating within large, oversize bearings; Eccentric shafts with a variable weight counterweight system creating circular; throw action; Two bearing or four bearing, circular throw screens; Crowned or flat decks; Crown bars with rubber liners and lined vibrator tubes; Pivoting motor bases
