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 or cold grinding is the ideal solution for pulverizing samples that cannot be reduced to the required fineness at room temperature. This procedure involves the use of grinding aids such as liquid nitrogen (-196 °C, embrittlement of the sample outside the mill) or dry ice (-78 °C, sample/dry ice mixture) to embrittle the sample ...
