Product description

A test sieve is an instrument which is used for the measurement of particle size. In its most common form it consists of a woven wire screen, with square apertures, rigidly mounted in a shallow cylindrical metal frame. For coarse sieving a perforated plate screen with square or round holes may be used in place of wire mesh. Square hole perforated plate sieves range down to 4 mm and round hole sieves down to 1 mm aperture. The sizes of solid particles from 125 mm down to 20 µm can be measured rapidly and efficiently by means of standard test sieves. Special sieves with apertures smaller than 20 µm are available, but it should be appreciated that the finer a screen is, the more easily will certain types of particulate solids tend to block or blind the apertures. Nevertheless, ‘micro’ sieving can be carried out down to 5 µm using special techniques. Particle size, as measured by test sieving, may be specified simply by quoting two sieve sizes, one through which the particles have passed, and the other on which they are retained

However, the most frequent use of test sieving is for measuring the size spread, i.e., the particle size distribution. Test sieving is not the only method available for particle size analysis, but it is certainly the most widely used and probably the most important.

The Steel Sieve is of impeccable quality. Multiple points of inspection are built into the manufacturing.The die-formed frame assures a proper fit, superior quality and performance, guaranteeing that the American Society for Testing Materials (ASTM) specifications are always met. Serialized to meet the highest grade quality assurance systems for traceability of measurement devices. The serial number is etched on each sieve, and contained in a bar-coded label, tracing vital information such as when sieve was manufactured and which lot of wire cloth was used to manufacture each sieve. Comes with a Certificate of Compliance applicable to ASTM E 11 specifications bearing the serial number of your sieve and the ship date. All safeguards are in place to support and ensure your quality assurance program
