  • Vibratory conveyor
    Patent number: 5056652
    Abstract: The invention discloses a vibratory conveyor arranged so that the vibrations have a substantially greater horizontal than vertical movement. More particularly, the vertical acceleration of material carried by the material-carrying member is less than the acceleration of gravity and therefore the material conveyed does not physically leave the surface of the material-carrying member. The result is a smooth flow of material from one end of the material-carrying member to the other.
