Testing sieves are a cost-effective quality control product for particle size analysis. Stainless steel test sieves are known for being durable with non-corrosive properties which are not altered by water and are preferable for wet sieving such as food applications, aggregates, mining, and pharmaceuticals. Brass sieves are more cost efficient but less durable. Test sieves are commonly used for separating, fractioning, and particle size measurement of fertilizers, coffee, construction materials, plastics, soils, cement clinker and more. They are often used in many industries, from agricultural, chemicals, construction, to pharmaceuticals.
