US3900975A - Cryogenic grinding of copper - Google Patents

A process for abrasively grinding copper comprising (1) cooling the entire copper workpiece to a cryogenic temperature and (2) abrasively grinding the copper workpiece while it is at said cryogenic temperature. The workpiece is preferably immersed in liquid N2 during the abrasive grinding thereby preventing adhesive wear from occurring at relatively high metal removal rates.

Cryogenic Distillation - an overview | ScienceDirect Topics

Distillation processes uses cryogenic distillation to remove acid gases from a gas stream. The process is applied to remove CO 2 for LPG separation or where it is desired to produce CO 2 at high pressure for reservoir injection or other use. 9.8.1.2 Process Description. The process consists of two, three, or four fractionating columns.

Cryogenic Grinding | PDF | Cryogenics | Mill (Grinding)

CRYOGENIC GRINDING What is Grinding Grinding is a process of reducing the size of solid materials by mechanical action, dividing them into smaller particles. Perhaps the most extensive application of grinding in the food industry is in the milling of grains to make flour, but it isused in many other processes.

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.
