Temperature and friction sensitive substances are hard to mill as they are likely to become sticky during processing. Cryogenic milling uses liquid nitrogen to freeze substances to - 140°C, so they become brittle and fit for milling. Liquid nitrogen freezing is the most environmentally friendly one among cryogenic freezing methods.
- Milling to temperature sensitive and even elastic substances which are otherwise impossible to mill
- Milling of plastics into powder ranging from 800 to 200 microns.
- Suppressed recovery and recrystallization
- Fine grain structures and rapid grain refinement
- Environmentally friendly
