Abstract

"PRODUTOS DE CAULIM E SUA PRODUçãO". Método de produção de um material particulado de caulim adequado para uso como carga melhorada de SC incluindo as etapas de : (a) preparar uma suspensão de alimentação aquosa de caulim; (b) tratar o caulim da suspensão de alimentação por moagem por atrito em um vaso de moagem usando grânulos de meio de moagem; (c) transferir uma suspensão aquosa do caulim moído na etapa (b) a um classificador de tamanho de partícula e separar o caulim da suspensão em uma fração grosseira e uma fração fina; (d) retornar uma suspensão aquosa da fração grosseira produzida na etapa (c) para o vaso de moagem para ser adicionalmente moída por atrito; e (e) extrair uma suspensão aquosa da fração fina produzida na etapa (c) como uma suspensão de produto; em que o caulim da suspensão de alimentação da etapa (a) é tal que não mais que 30 % em peso tem um tamanho de partícula inferior a 2 <109>m e não mais que 30 % em peso tem um tamanho de partícula superior a 10 <109>m e em que o caulim da suspensão de produto produzida na etapa (e) tal que não mais que 10 % em peso tem um tamanho de partícula superior a 10 <109>m e não mais que 10 % em peso tem um tamanho de partícula inferior a 0,25 <109>m.
