LNG ULTRALOW TEMPERATURE PULVERIZATION SYSTEM USING LNG

摘要

An cryogenic grinding system using LNG is disclosed. Cryogenic grinding system according to an embodiment of the present invention includes a brine tank 120 is stored brine solution; An LNG tank 110 storing LNG at a temperature lower than the temperature of the brine solution; A heat exchanger (130) for cooling the brine solution through heat exchange between the brine solution and the LNG; A brine solution line 125 through which the brine solution in the cold storage state is circulated; And a grinder 150 in which the internal temperature is maintained at an extremely low temperature in the range of -60°C to -160°C by the brine solution line 125.
