Cryogenic grinding - Wikipedia

Freezer milling is a type of cryogenic milling that uses a solenoid to mill samples. The solenoid moves the grinding media back and forth inside the vial, grinding the sample down to analytical fineness. This type of milling is especially useful in milling temperature sensitive samples, as samples are milled at liquid nitrogentemperatures. The idea behind using a solenoid is that the only "moving part" in the system is the grinding media inside the vial. The reason for this is that at liquid nitrogen temperatures (–196°C) anyCryo Milling | Material Milling | AVEKA,Cryogenic milling, or cryo-milling, is the process of using liquid nitrogen to lower the temperate of the material and/or the milling process. AVEKA ‘s cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns.
