Cryogenic processing refers to the use of liquid nitrogen to freeze tyre chips or rubber particles prior to size reduction. Most rubber becomes brittle or "glasslike" at temperatures below 80°C. Typically, the size of the feed material is a nominal 2inch chip or smaller. The material can be cooled in a tunnel style chamber, immersed in a
Cryogenic grinding has been successfully used to produce powder coatings, food products and pharmaceuticals as well as in recycling plastics materials and tires. Linde has over 30 years'' experience in cryogenic grinding; we gladly pass this knowledge on to customers by helping them choose new equipment and retrofit existing facilities.

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.

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.
