VIBRATION DEVICE FOR AN APPARATUS FOR CONVEYING A METAL CHARGE IN A MELTING PLANT

摘要

Vibration device (10) for a conveyor apparatus which is able to convey a metal charge towards a container of a melting plant and which comprises at least an oblong bearing structure (20) having a conveyor channel (21) and supported by supporting elements which allow it to oscillate, or vibrate, at least in a longitudinal direction (X). The vibration device (10) is fixed to the bearing structure (20) and comprises at least a first pair of eccentric masses (35a, 36a) mounted off-axis on two corresponding bearing shafts (40, 41) able to rotate in synchrony with each other in order to feed in this way the metal charge on the conveyor channel (21) towards the container. A first eccentric mass (35a) is angularly out- of-phase by an angle (phi) other than zero, with respect to the second eccentric mass (36a) of the same pair of eccentric masses (35a, 36a).
