Benefits of Cryogenic Grinding Pulva

The cryogenic grinding process has many names, including freezer milling, freezer grinding, cold grinding and cryomilling. Cryogenics is one of three toll grinding techniques — dry and wet grinding being the other two. Cryogenic grinding is unique because it is reserved for situations where the materials cannot be reduced by dry or wet milling.

Toll Processing by OGL: Cryo grinding (cryogenic milling) solves all ...

Cooling soft, oily, or flexible materials with OGL liquid nitrogen to 320° F (196° C) embrittles them, so they can be ground to ultrafine particle sizes, often below 50 micron (250 mesh). 1. Ultrafinely ground particles offer superior liquid dispersion and penetration. 2. Wet, oily, or soft materials can be ground at cryogenic temperatures.
