  • Low pressure ultra-high energy cryogenic impact system
    Patent number: 5775603
    Abstract: The present invention relates to an ultra-high energy impact system for reducing the particle size of materials to an average diameter as small as about 40 .mu.m. The system includes a cooling station for cooling the materials to a temperature within the range of from about -40.degree. F. to about -450.degree. F. by direct contact with refrigerant, preferably liquid refrigerant; a milling station for reducing the particle size of the cooled materials which does not require direct cooling by refrigerant and which includes a rotor or rotors each operating at a tip speed within the range of from about 500 to about 1500 feet per second; and an atmosphere modifier for reducing the pressure of the gaseous atmosphere within the milling station to less than 20 inches of mercury absolute.
