About Frewitt
Frewitt Fabrique de Machines SA, headquartered in Granges-Paccot (Switzerland), has been developing and manufacturing machines and systems for powder processing since 1946. The portfolio includes mills and milling platforms (including FlexMill, EasyMill) for size reduction, milling, sieving, cryogenic milling, nano milling and micronization – for dry and wet processes. In addition, Frewitt offers systems for dosing, handling (such as debridging, weighing, sampling, filling), high containment, filtration as well as conveying and homogenization of powders, granulates and suspensions. The company delivers turnkey installations for the pharmaceutical, fine chemical, food and battery industries, including anode and cathode processes. The Total-Care concept includes product and safety monitoring (e.g. Contact Detector, metal detector, temperature monitoring), after-sales service, validation and certification (ATEX/FDA), training as well as a technology center with demo machines. Contact materials are typically stainless steel AISI 316/316L or AISI 304/304L.
