ISO 20977-2018 石灰材料--干法和湿法筛分粒度分布的测定 Liming materials — Determination of size distribution by dry and wet sieving
This document specifies two methods for the determination of the particle size distribution of liming <br />materials.<br />Method A (the dry sieving method) is applicable to all liming materials except wet and paste-like <br />products. Method A is not applicable if blinding, caking, electrostatic charges or agglomeration occur <br />after drying.<br />Method B (the wet sieving method) is applicable to products which are susceptible to blinding, caking, <br />electrostatic charges or agglomeration after drying. Method B can be used to determine the primary <br />particle size distribution of granulated products. Method B is not applicable to burnt lime and liming <br />materials containing water-soluble constituents....
