A particle blast apparatus includes a hopper assembly, which is mechanically isolated from the rest of the particle blast system. Energy is imparted to the hopper by an impulse assembly, which preferably is mounted directly to the hopper. The hopper is mounted to the apparatus on a slide assembly, which allows the hopper to be moved to a second position at which particles may be discharged from the hopper exit away from the particle feeder.

Particle blast apparatus

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.
