Primary and Secondary Cleaning
The cyclone and diffuser combination assist with the
primary cleaning. As discussed, the more air introdu-
ced at the diffuser the stronger the inner vortex and
the more fines are removed. The adjustable air inlet
(5) can be easily adjusted up and down which will
cover the air slots on the diffuser. We suggest that the
initial covering of the slots start from the bottom. For
example, when the slots are totally open on the
diffuser, the adjustable air inlet (5) should be positio-
ned below the slots.
Cyclone Basket Options
For maximum cleaning the open cyclone basket (3B)
is recommended. This basket allows a free passage
for the lighter material to discharge. It should be noted
that some of the heavier material may become
entrained in the upward vortex and exits with the
lighter material. The result is a very clean regrind with
some useable material existing to the dust drum. The
closed cyclone basket (3A) has been designed to mi-
nimize any carry over of useable material to the dust
drum. Any large particulate that becomes entrained in
the upward vortex hits the bottom plate and falls back
down. The lighter material travels around the bottom
plate and exits to the dust drum.
Kongskilde will advise you on the best cyclone basket
for your application
Secondary Cleaning:
The Air Wash System provides secondary cleaning af-
ter the airlock. Directly underneath the airlock are two
cascaders (9). The rotary airlock volumetrically feeds
the primary cleaned material through a set of casca-
ders. The cascaders have a set of baffles in them that
deflect the material over a slight vacuum. The fines
are vacuumed off the particulate as they pass over the
baffle plates.
A set of slide gates (11) positioned at the bottom of the
diffuser allow the operator to open or close the slide
gates. When secondary cleaning is not required the
slide gates are to be closed. We recommend that the
slide gates be fully open or fully closed. Partially
closing the slide gates could lead to material settling
in the pipes which will eventually block off the required
vacuum.
