In cryogenic grinding processes it is necessary to use liquid nitrogen to produce very high quality powders. The material to be milled is sent from the feed hopper through the dosing screw to the paddle screw cooler.

Liquid nitrogen is sprayed onto the material to be ground, which is then fed into the mill together with the nitrogen, thereby cooling the entire grinding process occurring within the mill.

A special temperature controller and liquid nitrogen control valve unit supplied by Messer monitor and regulate the amount of nitrogen necessary to achieve the required temperature.
