· Vibratory feeders utilize both vibration and gravity to move material forward. The force of gravity influences these parts to shift direction, causing them to move down or laterally. Simultaneously, vibration is employed to trigger the material’s movement. In response, the material on the feeder moves in imperceivable tiny hops or jumps.

Željko V. DESPOTOVIĆ, Aleksandar PAVLOVIĆ, Jelena RADAKOVIĆ. Abstract— Vibratory screens are machines that, when subjected to the mechanical vibration, carry out the separation of material mixtures to granulation, or to fractions. The number of fractions depends on the number of storeys on a vibrating screen.
