To me, there are two separations needed.
* One is centrifugal force to keep heavier than air dust at the outer diameter.
* Also very important, is the initial downward airflow and then backup (thus dust separation) of the air to outlet by placing outlet pipe lower than the inlet (thus forcing the downward airflow speed).
To me, the open slot can be 360 degree instead of 240 degree to encourage more centrifugal air speed.
Or, an angled baffle at the start of closed slot area to force downward speed for more separation.
