筛分

Based on screening and sampling,properties of trass and trass concrete in Ximeng area of Inner Mongolia was studied.

通过筛分样,对内蒙古锡盟地区大量蕴藏的及混凝土进行了材料性能实验研究。

Based on single machine check test,small screening test,combustible withdraw rate calculation and flotator complete index calculation,prove that the flotation result is very well.

通过机的单机检试验、小筛分试验、可燃体抽出率的计算、机完善指标的计算,证机的效果良好。
