Abstract
The invention concerns a detachable assembly for spot feeding alumina to a tank for the production of aluminum. A fixed hopper is made integral with horizontal metal girders which form at least part of its side walls. The hopper is provided with a bottom aperture for discharge of alumina therethrough. An impervious metal case is positioned vertically in said hopper with the upper part of the case open and substantially at the level of the upper part of the hopper. The case has two substantially parallel vertical branches, the first branch opening, at its lower portion, outside the hopper, and the second branch opening, at its lower portion, inside the hopper, in the immediate vicinity and on the axis of the aperture for the discharge of alumina.
