  • METHOD AND APPARATUS FOR MINIMIZING ICE BUILD UP WITHIN BLAST NOZZLE AND AT EXIT
    Publication number: 20260138234
    Abstract: A method and apparatus keeps ice from interfering with the flow of cryogenic particles entrained in a flow exiting a blast nozzle during continuous operation of a particle blast system. A fluid stream having appropriate temperature, moisture content and flow rate flows through an annular passageway which surrounds the nozzle.

  • Particle feeder
    Patent number: 10737890
    Abstract: An apparatus is described which introduces cryogenic particles received from a source of particles, having a first pressure, into a moving transport fluid, having a second pressure, for ultimate delivery to a workpiece or target as particles entrained in a transport fluid flow which seals between the source of particles and the transport fluid flow.
