Zusammenfassung:An apparatus for electrolytic surface treatment of bulk goods includes a tank for the acceptance of the treatment bath, an arrangement for connecting the goods to be treated to at least one pole of an electrical source, an electrode disposed in the bath connected to the other pole opposite the one pole, a vibratory conveyor having a helically ascending conveyor track and an arrangement for receiving the goods from the end of the conveyor track and returning them to the beginning of the track by a return device so that they will pass through the bath at least one more time. The arrangement for receiving includes a switch arrangement for selectively shifting the goods discharged from the end of the track between the return device and a discharge station. The apparatus is particularly suitable for electro-deposition of aluminum from an aprotic, oxygen-free and water-free, aluminum-organic electrolyte.
