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).

The term ambient grading, used in the context of plastics particle reduction, applies to systems where the starting material is fed to the grinding mill at, or slightly below, the ambient temperature. In cryogenic grinding, the starting material temperature is reduced to well below -100°C just before grinding.
