24、如 200目，就是该物料能通过1英寸*1英寸内有200个网孔的筛网。以此类推，目数越大，说明物料粒度越细；目数越小，说明物料粒度越大。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。各国标准筛的规格不尽相同，常用的泰勒制是以每英寸长的孔数为筛号，称为目。例如100目的筛子表示每英寸筛网上有100个筛孔。筛孔尺寸与标准目数对应筛孔尺寸：4.75mm标准目数：4目筛孔尺寸：4.00mm标准目数：5目筛孔尺寸：3.35mm标准目数：6目筛孔尺寸：2.80mm标准目数：7目筛孔尺寸：2.36mm标准目数：8目筛孔尺寸：2.00mm标准目数：
