Types of sieves
Datetime:2015-02-09 Hits:
Woven wire mesh sieves
Woven wire mesh sieves are according to technical requirements of ISO 3310-1.These sieves usually have nominal aperture ranging from 20 micrometers to 3.55 millimeters, with diameters ranging from 100 to 450 millimeters.
Perforated plate sieves
Perforated plate sieves conform to ISO 3310-2 and can have round or square nominal apertures ranging from 1 millimeter to 125 millimeters.The diameters of the sieves range from 200 to 450 millimeters.
American standard sieves
American standard sieves also known as ASTM sieves conform to ASTM E11 standard. The nominal aperture of these sieves range from 20 micrometers to 200 millimeters, however these sieves have only 8 and 12 inch diameter sizes.
Engineering applications
Gradation is usually specified for each engineering application it is used for. For example, foundations might only call for coarse aggregates, and therefore an open gradation is needed.
Forecast
Within the last years, some methods for particle size distribution measurement were developed which work by means of laser diffraction or digital image processing.
