Cryogenic Grinding of Thermoplastics and Elastomers

In addition, the mill throughput is significantly increased. In particular, cooling the grinding process with cryogenic gases in the case of heat-sensitive substances prevents a rise in temperature which results from the conversion of the electrical energy of the mill motors. This prevents melting and sticking of the ground material. GAS

Cryogenic grinding

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 example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. .
