Cryogenic grinding can be mechanically difficult, requiring expertise to manage moisture, clumping and other important quality elements. Why use cryogenic grinding: Some polymers require the use of cryogenic grinding in order to reduce the particle size. Given certain polymer properties, some materials do not behave in a way that is necessary
cryogenic temperatures is the relatively high CTE (coefficient of thermal expansion) of polymers compared with the CTEs of other industrial material such as metals and ceramics. Clearly, if a plastic component shrinks more during cooling than a mating metal or ceramic part, it can result in

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).
