  • ICE BLASTING SYSTEM AND METHOD
    Publication number: 20190255675
    Abstract: A blast cleaning system has a nozzle configured to deliver a pressurized blast cleaning media. The blast cleaning media includes a pressurized fluid and water ice particles as the primary blast cleaning component. The system includes an input hopper configured to accept supplied water ice in bulk form from an outside source. The system further includes a particle sizing module configured to produce the water ice particles for the pressurized blast cleaning media from the supplied water ice after the supplied water ice has been accepted into the input hopper.
