A particle blast cleaning apparatus incorporates a pressurized container which is pressurized by the transport gas upon start up through a feeder which does not comprise an airlock. The feeder introduces the blast media into the transport stream. At start up, the transport gas pressurizes the container, flowing upwardly through the feeder until the container is substantially pressurized and the flow substantially ceases. The feeder rotor may be configured to crush or grind the particles.

1. A particle blast cleaning apparatus, comprising: a. a container having a container exit, said container defining an internal cavity, said internal cavity being configured to prevent substantial pressure leakage out of said internal cavity and to have particles disposed therein;b. an internal passageway in fluid communication with said container exit, said internal passageway comprising: i. a feeder assembly having a feeder inlet at which particles are received from said internal cavity, a discharge station downstream of said feeder inlet at which particles are discharged, and a rotor interposed between said feeder inlet and said discharge station, said feeder inlet being in fluid communication with said container exit, said feeder not comprising an airlock; andii. an exit configured to be placed in fluid communication with a delivery hose; andc. an inlet port connectable to a source of pressurized transport gas, said inlet port configured to deliver pressurized transport gas into said internal passageway downstream of said feeder inlet. 2. The particle blast cleaning apparatus of claim 1, wherein said rotor is configured to grind or crush particles. 3. The particle blast cleaning apparatus of claim 2, wherein said rotor comprises a plurality of spaced apart discs carried by a rotatable shaft. 4. The particle blast cleaning apparatus of claim 3, wherein each of said plurality of spaced apart discs includes a respective outer periphery, the respective periphery of each of a plurality of said plurality of spaced apart discs configured as a series of teeth. 5. The particle blast cleaning apparatus of claim 1, wherein said rotor comprises a circumferential surface and a plurality of pockets disposed in said circumferential surface. 6. The particle blast cleaning apparatus of claim 1, wherein said inlet port is configured to deliver transport gas adjacent said rotor. 7. The particle blast cleaning apparatus of claim 1, wherein said inlet port is configured to deliver transport gas downstream of said rotor. 8. The particle blast cleaning apparatus of claim 1, wherein said container comprises sealable opening configured to receive particles. 9. A method of entraining particles in a flow of pressurized transport gas, said method comprising the steps of: a. providing an internal cavity configured to hold internal pressure and to have particles disposed therein, said internal cavity having an internal cavity exit;b. providing an internal passageway in fluid communication with said internal cavity exit, said internal passageway including an exit configured to be placed in fluid communication with a delivery hose;c. initiating and continuing flow of transport gas into said internal passageway, including the steps of: i. flowing said transport gas from said internal passageway upon initiation of said flow of transport gas into said internal cavity for an initial period of time until such time as pressure within said internal cavity inhibits further substantial flow of transport gas into said internal cavity; andii. flowing said transport gas from said internal passageway out said exit. 10. The method of claim 9, wherein said internal passageway comprises a feeder assembly having a feeder inlet at which particles are received from said internal cavity and a discharge station downstream of said feeder inlet at which particles are discharged, said feeder inlet being in fluid communication with said internal cavity exit. 11. The method of claim 10, wherein the step of flowing said transport gas from said internal passageway upon initiation of said flow of transport gas into said internal cavity comprises the step of flowing transport gas first through said feeder prior to said transport gas flowing into said internal cavity. 12. The method of claim 11, comprising the step of disposing particles to be entrained in said flow of pressurized transport gas in said internal cavity, and wherein the step of flowing transport gas through said feeder comprises the step of pushing said particles away from said feeder assembly. 13. The method of claim 12, wherein upon expiration of said initial period of time, the step of pushing said particles away from said feeder assembly substantially ceases occurring. 14. The method of claim 12, wherein said feeder assembly comprises a rotor, and further comprising the step of rotating said rotor starting substantially concurrently with the step of pushing said particles away from said feeder assembly. 15. The method of claim 14, wherein the step of rotating said rotor is started after starting the step of pushing said particles away from said feeder assembly.
