5.2.2 Cyclone
If after adjusting the dust collector damper good media is still being drawn into the dust collector, it
may be necessary to adjust the cyclone vortex as well.
To test the position of vortex; first clean the dust collector waste bin. Operate the blast process for 10
minutes and then look inside the dust collector waste bin. A large quantity of usable blast media in the
waste bin indicates the vortex needs adjusting to reduce carry over. The absence of any dust at all
indicates the vortex needs adjustment to separate the dust which may be retained within the media
hopper.
A short vortex will usually draw more dust out of the cyclone than a long vortex. Each process may
need a different vortex setting, with best results being achieved by trial.
To adjust the length of the vortex in a motorized cyclone:
 Switch off the cyclone then the dust collector
 Open the access panel
 Slacken the tensioning clip around the vortex
sleeve
 Slide the sleeve up or down as required
 Replace and secure the tensioning clip and
close the access panel
To adjust the length of the vortex on a non-motorized
cyclone:
 Switch off the cyclone then the dust collector
 Open the access panel
 Release the thumb-screw securing the vortex
adjusting rod at the top of the cyclone exit
elbow.
 By means of the knob attached to the adjusting
rod, slide the rod up or down as required to
decrease or increase respectively the length of
the vortex.
 Secure the thumb-screw when the adjusting rod
is in the desired position.
 Close the access panel
NOTE: The position of the vortex can be viewed by opening the top access door during the
adjustment procedure.
