Among them, cryogenic grinding (also known as freezer grinding and cryomilling) is the act of chilling a material and then reducing it into a small particle size. A typical cryogrinding system principally consists of cryogenic precooler and cryogenic grinder (Ghodki, & Goswami, 2019 ).

Grinding at cryogenic temperatures creates ultra-fine particles in a very narrow distribution range. Coupled with our customizable sieving system, OGL can evenly classify materials to maximize the yield, stability, and performance of your product. Our sieving systems can be adjusted for a wide variety of application needs.

Cryogenic grinding involves the use of liquid nitrogen to chill pellets in advance of the grinding process. Once cooled, the pellets proceed through a mechanical mill. The use of liquid nitrogen to chill the pellets enables more effective size reduction. Cryogenic grinding can be mechanically difficult, requiring expertise to manage moisture ...
