cryogenic grinding question
Frequently asked questions | Cryogenic/freezer grinding ...
Does cryogenic grinding eliminate water (dry) in the material? No, it doesn't. Water contained in a material is frozen, so it will remain after grinding. However, just for your information, in grinding at room temperature, water may be decreased by heat generated from grinding.

OGL Toll Grinding and Cryo grinding FAQ - AAAmachine
Cryo grinding is effective for grinding flexible and organic materials—such as commercial food products and many polymers—that embrittle only at cryogenic temperatures. Cryo grinding is not an efficient milling technique for materials that are already brittle at ambient temperatures, or ones that will not embrittle when transitioned to cryogenic temperatures.

Grinding - Powder Plastic Europe
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).
