Comprehensive work related to cryogenic grinding – from consulting on the application of technology, design of cryogenic grinding line and structural elements, to the selection of appropriate system components – is carried out in cooperation with MESSER Polska. This allows our customers to run cryogenic grinding tests in the MESSER R&D centre.

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).
