5.1.2 Media pick-up tubes
The setting of the pick-up tube in the media box has a significant effect on the blasting performance.
Adjustment varies with the media density, with denser media requiring more air to circulate it.
The greater the flow of media from the mixer box to the blast gun, the higher the rate of wear on
media hose, blast nozzle.
 Check that there is a supply of free-flowing, dry media to the mixer box
 With compressed air flowing through the blast gun gradually move the pick-up tube into the
mixer box with the chamfer facing upwards while a colleague watches the media flow from the
nozzle.
The pick-up tube is in the right position when you are just able to see the media stream
leaving the nozzle. If the media stream is intermittent then the pick-up tube has been pushed
too far in.
o Moving the pick-up tube out decreases media flow
o Moving the pick-up tube in increases media flow
 Lock the pick-up tube in place with the retaining screw
 Further adjustment should not be needed whilst using the same media

O-ring is used to mark position of
the pick up tube in the mixer box.
This allows the tube to be
reinserted at the same position.
