Abstract (en)

[origin: EP2368638A1] The method involves milling the feedstock in a milling unit (2) and cooling the feedstock with a liquid cryogenic cooling agent before or during the milling process. The liquid cryogenic cooling agent is undercooled to a temperature below its boiling point before its delivery to the milling unit. The liquid nitrogen is used as a cryogenic cooling agent. An independent claim is also included for a device for fine milling of the mill material.
