16-05-2015· Precooling unit The cryogenic precooler is a cooling device made up of a screw conveyor enclosed in a properly insulated barrel and a system to introduce liquid nitrogen into the barrel, thereby providing refrigeration (liquid and cold gas) within the system. The function of the cryogenic precooler is to remove the heat from the material before it enters the grinder.
In order to grind tough and elastic materials with a high throughput into fine powder, an efficient cryogenic cold grinding system is required. The feed material must firstly be cooled with a suitable refrigerant such as e.g. liquid nitrogen to a defined temperature usually below the glass transition or softening temperature to cool.
