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.
Air Products' PolarFit® cryogenic grinding solutions can help you grind more effectively and efficiently, particularly for heat sensitive or tough-to-mill materials. Whether you have an existing cryogenic or ambient milling system that you need to upgrade, or plan to install a new system, we can help.
Cryogenic grinding is an innovative process that involves grinding plastic materials at extremely low temperatures to prevent melting. By subjecting the plastic to sub-zero temperatures, typically using liquid nitrogen or carbon dioxide, the material becomes brittle and can be easily ground down into a fine powder.

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).
