  • Patent number: 4274785
    Abstract: In the disclosed method and apparatus, an anode scrap pile is formed by piling anode scraps to be of a predetermined height. The anode scrap pile is conveyed to a substantially U-shaped inclinable chute having a rectangular bottom and parallel side walls rising from the opposed long edges of the bottom, the distance between the opposed side walls being slightly greater, preferably about 5 cm, than the height of the pile. The pile is then pushed with cylinders in toward the bottom of the above-mentioned inclinable chute which has the open side between the side walls directed in the horizontal direction and the side walls positioned horizontally so as to receive the anode scrap pile. The inclinable chute into which the anode scrap pile has been pushed is rotated with a cylinder so that the bottom of the chute is downward and the side walls of the chute are in the vertical direction.
