  • Feeder assembly for particle blast system
    Patent number: 7112120
    Abstract: A particle blast system includes a feeder assembly having a rotor with a plurality of pockets formed in the peripheral surface. The transport gas flowpath includes the pockets, such that substantially all transport gas flows through the pockets. The seal adjacent the peripheral surface is actuated by the transport gas pressure to urge its sealing surface against the rotor's peripheral surface. At start up, there is no substantial pressure between the seal and the rotor, reducing start up torque requirements.
    Type: Grant
    Filed: April 17, 2002
    Date of Patent: September 26, 2006
    Assignee: Cold Jet LLC
