Cryogenic Grinding | AGA Industrial Gases

To produce crumb rubber, it is necessary to reduce the size of the tire shred or chip. This is accomplished by techniques called cryogenic grinding. Cryogenic processing refers to the use of liquid nitrogen (−196°C) to freeze tire chips prior to size reduction. The rubber is immersed in liquid nitrogen to reduce the temperature of the tire chip.

Cryogenic grinding - Wikipedia

Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.
