摘要： 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.

摘要： Apparatus for transferring powdered ore from a storage tank to a bin associated with an electrolytic cell. The cell defines a chamber containing an electrolyte and includes means for transferring ore from the bin to the chamber. The apparatus comprises a fluidizing conveyor for conveying powdered ore from a storage tank to the bin, a first vent interconnecting the conveyor and bin and a second vent interconnecting the bin and chamber. In a preferred embodiment, a source of pressurized gas causes ore to flow through the conveyor, and the apparatus further comprises a pressure switch for closing the source in response to a buildup of fluid pressure in the conveyor. Another preferred feature is a fluidizing pad inside a conduit connecting the storage tank to the conveyor.

摘要： The invention relates to the feeding of finely divided particulate matter in a fluidized state from a source to a plurality of discharge points wherein discrete quantities of particulate matter are discharged by suitable feeding devices. In more detail, the invention comprises a primary air activated gravity conveyor and a plurality of secondary air activated gravity conveyors leading away from the primary conveyor to direct particulate matter to the feeding units associated with each secondary conveyor. The primary and secondary conveyors are maintained full of fluidized particulate matter at all times.
