With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).
