As a further aid to the separation of good media from dust and fines there is an adjustable airflow
separation control disc mounted on the top of the filler chute flap on a CY600 or an air-flow separation
control band around the body of the 75/16 cyclone.
This disc/band has slots cut in it which coincide with holes in the filler chute flap/cyclone body itself.
When all the holes are lined up, air is permitted to enter the cyclone increasing the amount of air
available for extraction to the dust collector. In turn this reduces the velocity of the exhaust air and
permits media to fall out of the airstream more easily. This is particularly beneficial with light media
(such as plastics) where the individual granules do not have sufficient mass to drop out of a moving
airstream.
Where it is not necessary or not required to increase the velocity of the exhaust airstream the
separator disc/band should be rotated so that the holes in the disc/band do not line up with the holes
in the filler chute flap/cyclone body; this will inhibit the entry of any extra air by this route and hence
leave the characteristics of the air-flow unchanged.
It must be remembered that the air-flow separation disc/band is adjustable to give all permutations
between fully open and fully closed; this provides the operator with a wide range of adjustment to suit
individual situations. However, it is also important to remember that there is no firm rule concerning
the use of this disc/band and the best results will be achieved by trial and error.
Once the cyclone has been set for a particular application, it should not require adjustment. Any loss
of visibility or a failure to remove sufficient dust may be caused by blocked breather pads or choked
dust collector filters.
To maximize operation, each different blasting operation will need the settings checking for best
blasting performance.
