Working Principle And Characteristics Of Cryogenic

The Cryogenic Grinding Mill system forms a closed-circuit circulation system during the material pulverization process, so that the energy is fully utilized and the energy consumption is saved: the temperature of the chilling source can be reduced to minus 196 degrees, according to the embrittlement temperature of the material. In the pulverization process, the temperature can be adjusted, the

Operating Principle. This cryogenic pulverizer uses liquid nitrogen as cooling medium.When crushed material is achieved at the brittle fractured state,it goes into mechanical pulverizing chamber and repeatedly impacts,collides,shears,mills by high speed rotation of blade and gear to reach the optimal crushing effect.The milled material has airflow grading machine to classify and collect.If the ...
