Cryogenic Grinding is the act of cooling or chilling a material and then reducing it to a small particle size. DNA is extracted from human teeth with the help of cryogenic grinding for PCR (Polymerase Chain Reaction) and RFLP (Restriction Fragment Length Polymorphism) based forensic analysis.
cryogenic grinding German translation – Linguee
During the cryogenic grinding process, the rubber granules are embrittled with liquid nitrogen and afterwards pulverized by means of impact crushing between counterrotating pin discs. Beim CryogenMahlverfahren wird Gummigranulat mit flüssigem Stickstoff versprödet und anschließend durch Prallzerkleinerung zwischen gegenläufig rotierenden Stiftscheiben pulverisiert.
(DOC) cryogenic grinding | nikhil gowda
Cryogenic grinding involves cooling a material below its embitterment temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture.
Cryogenic Grinding | AGA Industrigaser
Cryogenic Grinding Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. Waste materials can be separated by exploiting the coldness of liquid nitrogen.

Cryogenic grinding
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.
