摘要
对安徽某地天然重质碳酸钙进行超细分级试验研究 ,结果表明 ,采用磨矿 分级组合工艺 ,产品粒径细、粒度分布范围窄 ,且设备投资小 ,生产运行成本低 (比传统磨矿工艺节省 3 9元 /t) 。
The result of experimental study on superfine classification of GCC from a deposit of Anhui province indicated that,the particle size of product by grinding classificating composite technique is fine,and its particle size distribution is narrow,the investment of installations is less,the cost of production is lower and will be 39 yuan/t less than the traditional grinding techniquce.This technique comes to practice will open a new way for wet superfine technique of GCC.
