石灰材料 用干湿筛选法对粒度分布的测定

Calcium-/Magnesium-Bodenverbesserungsmittel. Bestimmung der Korngr??enverteilung durch Trocken-und Nasssiebung Liming materials. Determination of size distribution by dry and wet sieving Amendements minéraux basiques. Détermination de la distribution granulométrique par tamisage par voie sèche ou par voie humide

适用范围:This European Standard specifies two methods for the determination of the particle size distribution of limingmaterials.The dry sieving method (method A) is applicable to all liming materials except wet and paste-like products.Method A is not applicable, if blinding, caking, electrostatic charges or agglomeration occur after pre drying.The wet sieving method (method B) is applicable to products which are susceptible to blinding, caking,electrostatic charges or agglomeration after pre drying.Method B can be used to determine the primary particle size distribution of granulated products.Method B is not applicable to burnt lime and liming materials containing water-soluble constituents.
