【摘要】 本文提出一种湿法制备技术利用珍珠岩尾矿制备珍珠岩抛光磨料。与传统干法工艺相比 ,珍珠岩抛光磨料产品产率从 3 0 %提高到 70 %以上 ,颗粒粒度百分之百小于 15 0 μm ,而 0 -4 4μm粒级含量不到 10 %。粒度分布更加合理 ,完全满足玻壳行业及相关行业的要求。湿法制备珍珠岩抛光磨料是珍珠岩加工业充分合理利用珍珠岩尾矿的十分有效的利用途径。更多还原

【Abstract】 A wet preparation method was suggested to produce perlite abrasive grits from perlite tailings. The ouput rate of the abrasive grits by the new method increased to 75% compared to 30% by traditional dry process. The grit size was absolutely smaller than 150μm and the 0-44μm grade presented less than 10%, thus making the grit size distribution more reasonable and could meet the requirements of TV glass shell polising.更多还原
