Process screens / sieves

Process screens and sieves are perforated or mesh barriers that separate particles by size, either by passing material through a defined aperture during milling or by grading a sample into fractions for analysis. On Questpair, 95 percent of the listings are used, drawn from a catalogue of 234 items across 9 verified suppliers and distributors. The range spans new, used and refurbished screens, with prices from EUR 22 to EUR 8.178. Aperture size, material and the equipment the screen fits determine which one a laboratory needs. Sieve analysis, also called particle size distribution, underpins the laboratory work these components serve, from quality control on a milled powder to grading a sample before further processing.
