标准筛的目数与粒径的换算表.doc

标准筛的目数与粒径的换算表泰勒标准筛制：泰勒筛制的分度是以200目筛孔尺寸0.074mm为基准，乘或除以主模数2的平方根（1.141）的n次方（n1，2，3），就得到较200粗或细的筛孔尺寸，如果用副模数2的四次方根（1.1892）的n次方去乘或除0.074mm，就可以得到分度更细的一系列目数的的筛孔尺寸，下面列表的筛孔尺寸是采用副模数来分类的。目数筛孔尺寸网丝直径目数筛孔尺寸网丝直径ma(mm)d(mm)ma(mm)d(mm)320.4950.3001150.1240.097350.4170.3101500.1040.066420.3510.2541700.0890.061480.2950.2342000.0740.053600.2460.1782500.0610.041650.2080.1832700.0530.041800.1750.1423250.0430.0361000.1470.1074000.0380.025筛网目数及标准筛的网孔尺寸对照表分样筛 200x50mm 43只为壹套 材质为：铜框、镀铬框、镀锌框 筛孔目数筛孔目数mm目mm目4.050.180853.260.170902.580.1501002.0100.1351101.6120.1251201.43140.1111301.25160.1051401.00180.1001500.90200.0971600.80240.0911700.71260.0881800.63280.0801900.60300.0762000.56320.0702200.50350.0652400.45400.0632500.40450.0572600.355500.0552800.315550.0543000.300600.0483200.25065无孔筛底盖0.220700.20080目数粒度对照表目数粒度um目数粒度um目数粒度um5 390014010416001010 2000170891800816 11902007420006.520 8402306125005.525 710270533000530 5903254435004.535 5004003840003.440 4204603050002.745 3505402660002.550 2976502170001.2560 2508001980150110013120 124130011分样筛200x50mm 10只为壹套 材质为：铜框铜丝网、镀铬框铜丝网、镀锌框铜丝网筛孔目数mm目0.90200.45400.3600.20800.151000.1251200.1051400.0971600.0881800.076200无孔筛底盖标准筛 200x50mm 10只为壹套 材质为：镀铬框筛孔目数mm目0.9200.45400.28600.180800.1541000.1251200.1051400.0981600.091800.074200无孔筛底盖新标准石子筛 300x70mm 12只为壹套 有冲框和镀铬规格孔径（mm）铁板园孔2.5铁板园孔5铁板园孔10铁板园孔16铁板园孔20铁板园孔25铁板园孔31.5铁板园孔40铁板园孔50铁板园孔63铁板园孔80铁板园孔100铁板园孔底盖砂石筛 200x50mm 8只为壹套 有冲框和镀铬规格孔径（mm）铁板园孔10.00铁板园孔5.00方孔铜网2.50方孔铜网1.25方孔铜网0.63方孔铜网0.315方孔铜网0.160方孔铜网0.080方孔铜网底盖分样筛 200x50mm 43只为壹套 材质为：铜框、镀铬框、镀锌框 筛孔目数筛孔目数mm目mm目4.050.180853.260.170902.580.1501002.0100.1351101.6120.1251201.43140.1111301.25160.1051401.00180.1001500.90200.0971600.80240.0911700.71260.0881800.63280.0801900.60300.0762000.56320.0702200.50350.0652400.45400.0632500.40450.0572600.355500.0552800.315550.0543000.300600.0483200.25065无孔筛底盖0.220700.20080筛网目数及标准筛的网孔尺寸对照表分样筛 200x50mm 43只为壹套 材质为：铜框、镀铬框、镀锌框 筛孔目数筛孔目数mm目mm目4.050.180853.260.170902.580.1501002.0100.1351101.6120.1251201.43140.1111301.25160.1051401.00180.1001500.90200.0971600.80240.0911700.71260.0881800.63280.0801900.60300.0762000.56320.0702200.50350.0652400.45400.0632500.40450.0572600.355500.0552800.315550.0543000.300600.0483200.25065无孔筛底盖0.220700.20080目数粒度对照表目数粒度um目数粒度um目数粒度um5 390014010416001010 2000170891800816 11902007420006.520 8402306125005.525 710270533000530 5903254435004.535 5004003840003.440 4204603050002.745 3505402660002.550 2976502170001.2560 2508001980150110013120 124130011分样筛200x50mm 10只为壹套 材质为：铜框铜丝网、镀铬框铜丝网、镀锌框铜丝网筛孔目数mm目0.90200.45400.3600.20800.151000.1251200.1051400.0971600.0881800.076200无孔筛底盖标准筛 200x50mm 10只为壹套 材质为：镀铬框筛孔目数mm目0.9200.45400.28600.180800.1541000.1251200.1051400.0981600.091800.074200无孔筛底盖新标准石子筛 300x70mm 12只为壹套 有冲框和镀铬规格孔径（mm）铁板园孔2.5铁板园孔5铁板园孔10铁板园孔16铁板园孔20铁板园孔25铁板园孔31.
