Cryogenic Grinding. 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. Thus, the pellets enter the mill and before grinding they
The Knife Mill GRINDOMIX GM 300 is suited for cryogenic grinding mainly of food samples, with the restriction that only dry ice and no liquid nitrogen can be used as the mill is not designed for temperatures as low as -196 C.
