Traditional particle analysis via conventional sieve analysis is an important analytical component across a broad spectrum of industrial sectors as well as numerous scientific fields. It is employed when detailed knowledge on the particle size distribution within a particular medium is desired – typically one of the most fundamental parameters to be determined when characterizing a material. Quality of the sieves can have a major impact on the reliability of such analyses.

Blau-Metall offers a palette of products – including Woven Wire Cloth Test Sieves and test sieves fitted with perforated plates featuring round, square and slotted apertures – suitable for all types of screening tasks: hand sieving, conventional screening analysis of aggregates, dry- and wet-sieving. Our precision-aperture technology and rigorous optical inspections using modern Image Dimension Measurement Systems guarantees our sieves meet the highest criteria of national and international standards such as ISO 3310.

Blau-Metall also offers individual sieve solutions tailored to the unique requirements of your sieving task.
