Use Of Rotary Valves Beneath Cyclones
Yes, definitely, if your cyclones are connected in series. Otherwise you will not be able to balance the pressures between the two.

Rotary Valves / Cyclones
The purpose of the cyclone is to separate the particulate material from the airstream. Placement of an air lock (rotary valve) at the bottom of the cyclone forces the cleaned conveying air to exit the cyclone overhead.

You also will be able to control the amount of feen into the screw etc. with the airlock. ■
Re: Use Of Rotary Valves Beneath Cyclones
yes .
you need something to close the bottom of the cyclon so that the reverce vortex can do its work.
Your cyclone should have an apex where the vortesx can centrifugate the collected material , forming the reverse vortex that will exit trough the vortex follower.
if you allow your mayterial to sit in the cyclone your efficiency will deteriorate fast.
or if you allow air or gas to come in to the cyclone from the bottom .
again it is not only a rotary valve . you need a little bit more than that , there are many books on cyclons , I remember one authored by I believe Svarovsky, also the center for advanced engeneering studies (new brunswick) offers courses on cyclonic solids separation, wet and dry.
Good luck

Use of rotary valves beneath cyclones
The process will use two high efficiency primary and secondary cyclones to remove minus 3mm to fines material from a hot (120 C) air stream. The cyclones will discharge to a screw conveyor or chain conveyor (yet to be determined).
Do we need rotary valves beneath the cyclones. What advantages and disadvantages are there? ■
