The Detector Assembly uses the cryogenic (low-temperature) agent, liquid nitrogen, for cooling. Because of its low temperature (–196°C [–321°F)]), liquid nitrogen may burn the skin. When you work with liquid nitrogen, use the following precautions: NOTE: Please adhere to your company’s safety guidelines for handling liquid nitrogen.
CryoMill - Cryogenic grinding was never more convenient or efficient Some sample materials have properties which make size reduction at ambient temperature impossible. If, for example, very elastic materials need to be ground or volatile components have to be preserved for further analysis, it is essential to carry out cryogenic grinding.
Avant le broyage, refroidissez le mortier de porcelaine / zirconium et les pilons d'un système de broyage ( par exemple, CryoGrinder), ainsi que l'échantillon, en les mettant dans un flacon Dewar contenant de l'azote liquide (~ 500 mL). Attention: Suivez les procédures de sécurité organisationnelles lors de l'utilisation d'azote liquide.
paramètres optimaux de broyage ont été établis à 15 heures de broyage avec une vitesse de rotation de 300 RPM et un ratio massique de balles sur poudres de 24 : 1 pour la poudre préalliée. Dans le cas du mélange avec le magnésium pur, les paramètres optimaux ont été fixés à 15 heures, 300 RPM et 32 : 1.

Cryogenic grinding with liquid nitrogen is an effective means of obtaining ultra-fine and uniform particle size, while improving product quality and stability as well as production rates. Cryogenic grinding systems combine high-performance fine grinding with cryogenic cooling, helping …
A cryogenic experiment or system is normally dominated by the need to get something cold and keep it cold, with other elements of the design subservient to that. Generally, the need to operate at cryogenic temperatures makes even an otherwise simpleexperimentcomplicated,andthecolderyouneedto go, the harder life generally gets.
Cryogenic conditions also had the advantage to correct the negative milling effect of high moisture content (~20%) by freezing absorbed water and then removing its plasticizing effect. However, due to the limited gains obtained, cryo-milling was not considered worthwhile for straw fine milling, considering the investments and functioning costs.
