细度模数 meaning in English

fineness modulus
fineness moldulus
modulus of fineness
size modulus

This machine can triturate wet or all kinds hard grade of ore and ofther material , especially can make many sizes sands
适用于湿法细碎，粗磨各种硬度的矿石及其他物料，特别适用于人工造沙过程中调节细度模数。
Through reiterative study over years by the author , a new principle to express the relation between aggregate particles size and the surface area was proposed , that is the specific granularity , which could solve the problem of lack of correlation of fineness modulus to the specific surface area of the sand
摘要经多年反复研究，发现了集料粒度与表面积关系法则，提出了以“比粒度”表述砂石粒度的新方法，解决了以“细度模数”表述砂子细度的不足之处，即解决了细度模数与不同细度砂子的比表面积没有相关性的问题。
