Cryogenic grinding - Wikipedia
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size.For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liquid ...

the hopper to the grinding mill. Liquid nitrogen sprays onto the material as it moves along the conveyor, resulting in a high heat transfer coefficient on the pellet surface. This rapid cooling makes the material brittle and easier to grind by a variety of impact-type mills. C. Cryogenic grinding and tunnel freezer – for large materials
Cryogenic grinding: an independent voice
Grinding processes using liquid nitrogen fall into two types: temperature-controlled grinding and true cryogenic grinding. In the first type, the liquid nitrogen is injected directly into the mill, where it acts as a heat transfer medium rather than a refrigerant. Liquid nitrogen injection rate is controlled by a sensor that
