3.0毫米的筛子

筛孔尺寸和标准目数对照表 - 百度文库
所谓目数,是指物料的粒度或粗细度,一般定义是指在1英寸*1英寸的面积内(斜体部分有误)有多少个网孔数,即筛网的网孔数,物料能通过该网孔即定义为多少目数:如200目, 筛分粒度就是颗粒可以通过筛网的筛孔尺寸,以1英寸(25.4mm)宽度的筛网内的筛孔数表示,因而称之为“目数”。 筛子的目数和孔径对照表 目数粒度对照表筛子的目数和孔径对照表 - 百度文库对于200mm直径的筛子,物料密度在1200kg/m 3 以下取25g,1200~3000kg/m 3 时取50g,3000kg/m 3 以上时取100g。 一般认为筛分法的分析下限是50μm,用微目筛下限可扩大到10μm。标准筛 - 百度百科
