Raw material vibration screening device for building ceramic tile production

The invention discloses a raw material vibration screening device for building ceramic tile production. The screening device comprises a screening tank body, a vibration column body, a buffer assemblyand a screening assembly. The upper face and the lower face of the vibration column are connected with the upper face and the lower face in the screening tank through the buffer assembly correspondingly, so that the vibration column body can do linear vibration relative to the screening tank body, and the risk that the vibration of the vibration column body is transmitted to the housing of the screening tank body is reduced; the screening assembly is arranged on the outer surface of the vibration column body; the screening assembly comprises a coarse screening piece and a fine screening piece, wherein the inner rings of the coarse screening piece and the fine screening piece are both fixed to the outer surface of the vibration column body, and the outer rings of the coarse screening pieceand the fine screening pi
