Abstract

Process for grinding a fragile substance at cryogenic temperatures, which uses a liquefied gas inert to said substance and the vapors of this liquefied gas to cool the substance and to protect it from the ambient air, characterized by the fact that it is made to suffer to said substance a first cooling, by said vapors, then a second cooling, by the liquefied gas, up to a temperature in which the substance is brittle in all its mass and then the substance is ground in contact with the liquefied gas.
