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.
In addition they can be used for cryogenic grinding, combined grinding/drying, combined drying/blending and defibration of organic substances (such as paper, cellulose, etc.). Whirlwind Mills can be found in different industries, such as chemical, plastic, building material, and food industry.
Cryogenic deburring is a cryogenic process used to remove burrs and flash from plastic and die cast workpieces. The process works by tumbling and/or abrasively blasting the workpieces at cryogenic temperature levels. The low temperatures (approximately −195 °C (−319.0 °F)) are achieved using liquid nitrogen, liquid carbon dioxide, or dry ice.
The cryogenic treatment process was invented by Ed Busch (CryoTech) in Detroit, Michigan in 1966, inspired by NASA research, which later merged with 300 Below, Inc. in 2000 to become the world's largest and oldest commercial cryogenic processing company after Peter Paulin of Decatur, IL collaborated with process control engineers to invent the world's first computer-controlled "dry" cryogenic ...
