摘要
采用激光粒度测定仪、筛分和 SEM研究了磷石膏的颗粒级配和二水石膏晶体的形貌 ,测定了不同粒径磷石膏中杂质的种类和含量 ,测试了不同粒径磷石膏的性能。结果表明 :磷石膏的颗粒级配、形貌与天然石膏存在明显不同 ,磷石膏中的杂质含量随粒径不同而存在差异。
With a laser apparatus for particle measurement and by the means of dressing by screen and SEM, the grading and the crystal morphology of phosphogypsum and natural gypsum were studied. The properties of phosphogypsum, the categories of impurity and their quantities in phosphogysum with different particle grading were investigated too. Experimental results show: the grading and morphology of phosphogypsom differ obviously from natural gypsum′s, and the quantity of impurity is various with different grading of phosphogypsom.
