There are countless polymers that due to their low density and melting points, grinding with mills at a room temperature is not possible because the friction of the mill itself generates a temperature higher than the melting point of the polymer and therefore the polymer liquefy. With cryogenic grinding we solve this problem.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

The use of liquid nitrogen to chill the pellets enables more effective size reduction. 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.Certain polymers that become plastic or sticky at temperatures developed in ambient temperature grinding processes can also benefit from cryogenic grinding. Such cryogenic processes employ pulverizing equipment such as that marketed by Pulverizing Machinery Company of Summit, N.J. under the trademark MikroPul.
