Process to grind thermoset or thermoplastic materials - U ...
Cryogenic processes can also use "dry ice" (i.e., solid CO 2) or compressed CO 2 to embrittle the feed material prior to grinding. However, like liquid nitrogen, a great amount of energy is required to compress the CO 2 gas into "dry ice". These additional costs tend to limit the use of cryogenic grinding to high value materials.
Organic sea buckthorn powder - BERTRAND
Cryogenic grinding is used primarily when grinding at room temperature would lead to problems. This would be the case with the sea buckthorn berry due to its relatively high oil content. And since the berries already are shock frozen from the harvesting process, cryogenic grinding eminently presents itself to the production of sea buckthorn powder.
