What are Cryogenic Gases And How To Handle It Safely?

Sep 24, 2020Cryogenic liquids are liquids that have a normal boiling point below –130F. They happen to be some of the most commonly used industrial gases that are handled, transported and stored in the liquid state at cryogenic temperatures. These include nitrogen, hydrogen, oxygen, helium, and argon. All of the cryogenic liquids can produce very large

Cryogenic Grinding

This is accomplished by techniques called cryogenic grinding. Cryogenic processing refers to the use of liquid nitrogen (−196C) to freeze tire chips prior to size reduction. The rubber is immersed in liquid nitrogen to reduce the temperature of the tire chip. The cooled rubber is then ground in an impacttype reduction device.
