cryogenic grinding with liquid nitrogen

Cryogenic grinding involves cooling a material below its embrittlement 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.

Cryomill - the perfect mill for cryogenic grinding - RETSCH

The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
