A vibratory conveying apparatus for conveying material. The apparatus includes a bed (26) upon which material is conveyed, a counterbalance (16) supported on a plurality of isolation springs (34), a plurality of inclined drive springs (22) extending between the bed (26) and the counterbalance (16), and a plurality of stabilizers (24) for controlling movement of the drive springs (22) along their central axes. A first pair of vibratory motors (12), each having rotatable eccentric weights, are attached to the counter balance (16). The eccentric weights rotate in phase with one another to vibrate the bed (26) at a vibration frequency.
