Micronizing, Milling & Cryogenic Milling | ACU | Brenntag
Cold Grinding with the pin mill (Cryogenic Milling) Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus, the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.
