Title: Improvements in or relating to the production of sodium aluminate
IPC: C01F7/08
Filed: 1927-01-11
Abstract: 264,823. Aluminum Co. of America, (Assignees of Barnitt, J. B.). Jan. 21, 1926, [Convention date]. Sodium aluminate having a high content of water-soluble alumina is obtained by igniting at the surface a uniform layer of an intimate mixture of fuel, aluminous material, and sodium carbonate, and causing the fuel to burn rapidly through the mass, whilst the latter, which is preferably moistened to avoid dust and to make it porous, is maintained in a relatively quiescent state. The process may be carried out in the known form of apparatus shown in Fig. 1 comprising guides 1 - - 4 which are engaged by rollers 6 on cars 5 fitted with grate bottoms, which are propelled by a continuously rotated sprocket 10. A hopper 7 delivers the mixture to the cars to form a layer, say five inches thick, which is then ignited at the surface by gaseous or liquid-fuel burners 8, combustion of the fuel being completed by creating a downdraft by means of a suction box 11 connected by a pipe- 12 to a blower 13. The speed of the cars is so arranged that combustion of the fuel is completed during the passage of the cars over the suction box, and the sodium aluminate, which is obtained in a porous, granular condition, isdumped as the cars move downwardly over the guide 3. Crushed coal or coke, or sawdust, or shavings may be used as fuel.
