<p>The method involves inputting goods into a grinding container (2) comprising grinding bodies (3), where the goods are cut by the relative movement of the grinding bodies to each other and relative to a wall of the grinding container. The goods are cooled by direct contact with a cryogenic refrigerant i.e. liquid nitrogen, fed into the grinding machine during the grinding process. Separated oversized particles are again fed to the grinding container. The supply of the cryogenic refrigerant is controlled depending on the temperature measured in the grinding container. An independent claim is also included for a device for finely grinding solids.</p> |
