23、度可以以其粒徑為量度單位，亦可以以研磨篩上對(duì)應(yīng)的孔數(shù)作為測(cè)量單位。所謂目數(shù)，是指物料的粒度或粗細(xì)度，一般定義是指在1英寸（inch ） *1英寸（inch ）的面積內(nèi)有多少個(gè)網(wǎng)孔數(shù)，即篩網(wǎng)的網(wǎng)孔數(shù)，物料能通過(guò)該網(wǎng)孔即定義為多少目數(shù)：如200目，就是該物料能通過(guò)1inch*1inch內(nèi)有200個(gè)網(wǎng)孔的篩網(wǎng)。以此類(lèi)推，目數(shù)越大，說(shuō)明物料粒度越細(xì)，目數(shù)越小，說(shuō)明物料粒度越 大。 bigtoothh | 2009-08-24 11:15:59 目數(shù)編輯本段一、物理學(xué)術(shù)語(yǔ)顆粒目數(shù)的定義所謂目數(shù)，是指物料的粒度或粗細(xì)度。一般定義是指在1英寸*1英寸的面積內(nèi)的篩網(wǎng)，物料能通過(guò)該篩網(wǎng)，篩網(wǎng)的孔數(shù)即定義為目數(shù)。

24、如 200目，就是該物料能通過(guò)1英寸*1英寸內(nèi)有200個(gè)網(wǎng)孔的篩網(wǎng)。以此類(lèi)推，目數(shù)越大，說(shuō)明物料粒度越細(xì)；目數(shù)越小，說(shuō)明物料粒度越大。篩分粒度就是顆?？梢酝ㄟ^(guò)篩網(wǎng)的篩孔尺寸，以 1英寸（25.4mm）寬度的篩網(wǎng)內(nèi)的篩孔數(shù)表示，因而 稱(chēng)之為目數(shù)。各國(guó)標(biāo)準(zhǔn)篩的規(guī)格不盡相同，常用的泰勒制是以每英寸長(zhǎng)的孔數(shù)為篩號(hào)，稱(chēng)為目。例如100目的篩子表示每英寸篩網(wǎng)上有100個(gè)篩孔。篩孔尺寸與標(biāo)準(zhǔn)目數(shù)對(duì)應(yīng)篩孔尺寸：4.75mm標(biāo)準(zhǔn)目數(shù)：4目篩孔尺寸：4.00mm標(biāo)準(zhǔn)目數(shù)：5目篩孔尺寸：3.35mm標(biāo)準(zhǔn)目數(shù)：6目篩孔尺寸：2.80mm標(biāo)準(zhǔn)目數(shù)：7目篩孔尺寸：2.36mm標(biāo)準(zhǔn)目數(shù)：8目篩孔尺寸：2.00mm標(biāo)準(zhǔn)目數(shù)：
