Design of Cryogenic Grinding mill IJSRD

2017-3-29  The cryogenic precooler is a cooling device made of a screw conveyor which is enclosed in a properly insulated barrel and a system which introduces liquid nitrogen into the barrel, thereby providing refrigeration within the system. The function of precooler is to remove the heat from the material before it enters the grinder. The particle temperature must be low to enable the fracture in the grinder and to absorb the heat. Thus cryogenic precooler, must have ability to reduce the temperature of the material below its brittle point before it enters the grinding. Provision must be provided to control the feed rate to the grinder.
