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 to provide an inert environment.

A cryogenic milling operation is very similar to a normal, ambient grinding operation. It can be set up in many different ways, but the basic components may include: the mill, a cryogenic conveyor, liquid nitrogen flow controls, a liquid nitrogen supply system, and then other supporting equipment common to normal, ambient grinding operations.

OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).

The cryogenic temperature range is defined as from −238 °F to −460 °F, which is absolute zero, the point where molecular motion is as close to theoretically possible to stopping completely. Temperatures above −238 °F can, therefore, not be considered cryogenic. Any treatments applied at such temperatures won't qualify as cryogenic ...

Cryo grinding is effective for grinding flexible and organic materials—such as commercial food products and many polymers—that embrittle only at cryogenic temperatures. Cryo grinding is not an efficient milling technique for materials that are already brittle at ambient temperatures, or ones that will not embrittle when transitioned to cryogenic temperatures.

Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (-78 °C) or liquid nitrogen (-196 °C) that are capable of embrittling the sample by cooling and making it break more easily. An additional advantage is that the volatile components of the sample can be ...
