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) any

Cryogenic grinding: an independent voice

Grinding processes using liquid nitrogen fall into two types: temperature-controlled grinding and true cryogenic grinding. In the first type, the liquid nitrogen is injected directly into the mill, where it acts as a heat transfer medium rather than a refrigerant. Liquid nitrogen injection rate is controlled by a sensor that
