Liquid nitrogen is added until the temperature of the material is reduced to a predetermined set point. This set point is the glass transition temperature of the material finally the brittle material enters an impact (pin) mill where it is ground to the desired particle size. The computer controls the entire process of the cryogenic grinding system.
