With our cryogenic grinding plants we offer solutions for fine grinding lubricating and temperature-sensitive products. This process guarantees a technically perfect grinding result. In addition, cryogenic grinding – a process also known as cold grinding – prevents thermal damage to the material to be ground and corresponding grinding losses.
What does cryogenic mean?
Cryogenic stands for substances, processes and properties that are associated with extremely low temperatures. Well-known examples of cryogens are liquid hydrogen, whose boiling point is approx. -252°C, or dry ice with a sublimation point of -78.5°C. These substances are used in the cooling of superconductors or as fuel for rocket engines.
All plants are designed as closed systems with vortex screw cooler and liquid nitrogen cooling, corresponding dosing devices, separators and bunkers.
Fields of application
At Ebbecke Verfahrenstechnik we use our cryogenic mill for contract milling. Micronization, also known as fine grinding plays a special role in process technology; particle sizes are significantly reduced by milling.
