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
The company was founded in 1915 by F. Kurt Retsch. A few years later he registered his first patent in grinding technology: a mortar grinder that became famous worldwide as the “RETSCH Mill”.
This innovation replaced tiresome manual grinding with hand mortars which was the standard in laboratories at the time and earned RETSCH an excellent reputation in the international science and research community.
Today RETSCH is the leading solution provider for size reduction and particle sizing technology with subsidiaries in the US, China, Japan, India, South Africa, France, Italy, Benelux, Russia, UK and Thailand and an export share of 80%.
RETSCH’s philosophy is based on customer orientation and leading edge technology. This is reflected in instruments whose high-quality components are designed for perfect interaction. RETSCH products not only guarantee representative and reproducible results for grinding and particle analysis but also allow for easy and comfortable operation.
Since 1990 RETSCH has been part of the continuously growing VERDER group and formed the core of the group’s Scientific Division
