Sieving & Fractioning

Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:
  • the strength of concrete depends on the particle size of the cement
  • the taste of chocolate is influenced by the fineness of the cocoa
  • the flow characteristics and solubility of washing powders depend on the fineness and particle shape of the basic materials

RETSCH sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analysis.

Test Sieve Retsch

Test Sieves

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.

Evaluation Software

Evaluation Software

EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects, due to the fact that the software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data.
