Cryogenic Size Reduction / Grinding - Ancos

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.
