Processo para o tratamento de resíduo de escória de alumínio processo para a produção de um agregado e sistema de forno |
摘要 |
<p>A process for treatment of aluminum dross residue (NMP) having available aluminum nitride (AlN) and/or free aluminum (Al) and/or aluminum chlorides (AlCl3) having a particle size within the range of 0.3 to 300 microns, i.e., "fines" to produce a high alumina lightweight aggregate is described. The process is characterized in that the NMP is fed into a rotating sealed kiln and heated to a temperature in the range of 1090 to 2200 DEG C (2000 to 4000 DEG F) while feeding oxygen or a mixture of oxygen and water into the kiln with less than about 20% of the total heat energy input for heating the NMP to a temperature between 1090 and 2200 DEG C (2000 and 4000 DEG F) being supplied from an external source. The process does not require prior agglomerization of the fines. <IMAGE></p> |
