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 temperaturesbecause they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. Cryogenic grin…CRYOGENIC CRUSHING OF MATERIALS - VIRGIL C. WILLIAMS,A cryogenic process for disintegrating materials such as metals, plastics, rubber, foodstuffs; wastes such as scrap iron, garbage, etc. The process is employed for materials which have decreased impact resistance upon refrigeration to low temperatures and recovers the refrigeration from the material after disintegration and employs this refrigeration in cooling of the material.What is Cryogenic Processing? - Controlled Thermal Processing,Cryogenic air separation process is one of the most popular air separation process, used frequently in medium to large scale plants. It is the most preferred technology for producing nitrogen, oxygen, and argon as gases and/ or liquid products and supposed to be the most cost effective technology for high production rate plants.
