Liquid nitrogen - Import export

DG Grinding processes with simultaneous cooling of the raw material to temperatures far below ambient temperature (e.g. minus 30°C); usually done with the help of liquid nitrogen, which has a temperature of around minus 196°C.

Cryogenic Mill The solution for fine grinding temperature-sensitive products. Our cryogenic grinding plants enable fine grinding of lubricating and temperature-sensitive products. This not only results in a technically perfect grinding but in addition thermal damage of the ground material and resulting grinding losses are prevented by the cryogenic grinding. All plants are designed with swivel screw coolers and liquid nitrogen cooling, appropriate dosing devices, separators as well as bunkers as closed plants.
