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).
Particle size reduction: Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications ...
