DESCRIPTION & FUNCTIONS

4.4 BLAST UNIT – REBOUND CHAMBER (PLENUM)
Once the abrasive has impacted the work surface, the shot is directed into the
rebound plenum. This curved portion of the plenum absorbs a large percentage
of the force exerted by the high velocity abrasive and helps dissipate the heat
generated by the blast process.
4.5 BLAST UNIT – DEFLECTOR PLATE / HOPPER
This section refers to Figure 4.5.1 on page 23.
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. The contaminated abrasive hits the abrasive already at the
bottom of the plate and effectively absorbs any residual force left in the moving
mixture. The contaminated abrasive then falls through a curtain of high velocity
clean air, which physically separates the heavy abrasive and the lighter
contaminants. The air wash pulls the contaminants through the separator
towards the exhaust and eventually to the dust collector. The clean abrasive falls
to the bottom of the separator, then into a hopper where it can be recycled.
