Abstract: A method and apparatus for substantially continuously producing a stream of ice particulates P for use in performing ice blasting work on a work object W. The present invention includes an extruder assembly, a blast nozzle, and an ice-receiving line. The extruder assembly includes a pressure vessel within which the ice particulates are formed under elevated pressure. The extruder assembly further includes an ice discharge opening. The ice-receiving line has a first end adapted to receive a fluidizing gas from the pressurized air supply source and a second end connected to the blast nozzle. The ice-receiving line is in communication with the extruder assembly ice discharge opening. The pressurized ice particulates P are passed from the pressure vessel discharge opening to the pressurized ice-receiving line. The fluidized ice particulates move via pressure flow towards a blast nozzle to be expelled from the nozzle towards a work object.
