  • Page 15: Blast Unit - Abrasive Control Valve

    Operating Instructions 1-8DEZ Description and Function 3.2 Cont’d The blast wheel is equipped with a cast in place impeller for easy maintenance. This impeller pre-accelerates the abrasive to the wheel blades in controlled portions. The impeller also acts as a timing device to ensure proper placement of abrasive on the blade face.

    Operating Instructions 1-8DEZ Description and Function 3.5 Blast Unit – Deflector Plate / Hopper This section (3.5) refers to Figure Number 3 on page 15. Once the contaminated abrasive leaves the rebound plenum, it enters the separator and immediately encounters the deflector plate. The deflector plate slows the abrasive down even more before it enters a tray at the bottom of the deflector plate.
