The study of plastics in cryogenic environments started all the way back in the 1960s. The research was conducted by NASA, as they wanted to see how plastic would perform in environments below 150 degrees Celsius. They were invested in the findings because, at the time, NASA was looking for ways to improve the seals, pumps, valves, …
GAS APPLICATION. In order to grind tough and elastic materials with a high throughput into fine powder, an efficient cryogenic cold grinding system is required. The feed material must firstly be cooled with a suitable refrigerant such as e.g. liquid nitrogen to a defined temperature usually below the glass transition or softening temperature to ...

Cryomilling is a ball mill micronization process that is carried out at a low temperature (RETSCH, 2021). The grinding jar is cooled to ca. −196°C by liquid nitrogen supplied continuously ...
If this pre-cooled material is then ground in a mill, the sample shows brittle breaking behavior. Cryogenic grinding is also suitable for hard plastics even though this material is brittle at room temperature. For a successful size reduction process the temperature of the sample must not exceed the glass transition temperature.
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is …

Ultra-fine Particle Grinding. 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.
Finishing services such as fine, coarse, and cryogenic grinding services are also provided. Other services include packaging, repackaging, and screening. Suitable for sheets, …
Grinding spices: How does cryogenic grinding work? Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle.
