摘要: 为了更好地了解选煤厂浮选入料特性,对多座采用不同工艺流程的选煤厂的浮选入料小筛分试验数据进行了整理,并采用数理统计原理进行统计,结果表明:其分布特点及粒度符合罗辛—拉姆勒(R-R)方程式的分布规律,由此可预测任一粒级的产率。在缺乏煤质资料的条件下,可为建设新选煤厂提供参考依据。

Abstract: Abstract:This paper maily introduces rules of partical size and ash of flotation materias,concludes distribution characteristic s in different tecnological process,and verifies that the partical size with obvious relationship to R-R formula is in accordance with the regulation of the equation.Therefore,prediction of productive rates of any partical sizes is feasible.
