Retsch is the leading manufacturer of laboratory mills, jaw crushers and sieving equipment. With more than 100 years of experience, Retsch develops innovative solutions for neutral-to-analysis sample preparation and particle size analysis.

RETSCH sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analyses. Our sister company MICROTRAC is a technology leader, with an extensive global network and an unrivaled offering in particle characterization.

The well-proven RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the fabric of each test sieve is precisely joined into the frame and tautened.

Test Sieve: Diameter (English) Outer: 8 in. For Use With (Application) Ideal for cement clinker, chemicals, coffee, construction materials, fertilizers, fillers, flours, grains, Metals powders, Minerals, nuts, Plastics, sand, seeds, soils, washing powder etc.

The Air Jet Sieve AS 200 jet is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and deagglomeration. The option to store up to 10 SOPs and the automatic vacuum regulator (accessory) guarantees reproducible and meaningful results.

All sieving parameters – vibration height, time, and interval – are set, displayed and monitored digitally which makes operation of the AS 200 control very convenient and quick. Up to 99 standard operating procedures (SOPs) may be stored for routine analyses.

May 15, 2002 · Sieving is a practical and cost effective way to determine particle size distributions for coarser materials. Two accepted scales are the US Sieve and Tyler Mesh or equivalent scales. A table is provided that allows correlations between the two scales.

Jul 1, 2024 · Master sieve size chart with our easy guide. Learn how to navigate sieves, mesh sizes, and ASTM standards for precise particle analysis.

A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of ...

A molecular sieve is a material with pores (voids or holes), having uniform size comparable to that of individual molecules, linking the interior of the solid to its exterior. These materials embody the molecular sieve effect, the preferential sieving of molecules larger than the pores.
