【摘要】 本文采用振动磨制备磷渣超细粉,并对其进行了粉磨动力学的研究,导出了磷渣超细粉的粉磨速度方程。试验结果表明:磨后粉体的比表面积、特征粒径和均匀性系数与粉磨时间的对数或双对数呈线性关系。粉磨时间在0～30min时,粉磨效率较高,比面积增幅较快,而电耗增幅较缓。更多还原

【Abstract】 The grinding dynamics of phosphorous slag has been studied by vibration mill,and relational grinding rate equations of phosphorous slag have been derived.The results show that the specific surface area,characteristic diameter and uniformity coefficientof ground phosphorous slag powder are in lineal relation to logarithmic or log-log-arithmic of grinding time.When grinding time is from o to 30 minutes,grinding efficiency is higher and specific surface area has higher growth rate,and power consumption has lower growth rate.更多还原
