Working Principle And Characteristics Of Cryogenic Grinder

The Cryogenic Grinding Mill system forms a closed-circuit circulation system during the material pulverization process, so that the energy is fully utilized and the energy consumption is saved: the temperature of the chilling source can be reduced to minus 196 degrees, according to the embrittlement temperature of the material. In the pulverization process, the temperature can be adjusted, the

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
