tech,,,good catch. So, how would the bottom of the clam open to change bars, chains??? Aren't there stator bars/plates?
Wouldn't they get in the way of dropping the upper levels of rotating members?
Maybe they don't feel the need to have an easily removable assembly any longer? At least not for this particular "dewatering model"?
Will be fun to disect this one...lol
Thanks for posting the picts and the question. It makes sense, multiple stages, from the verticle size of the chamber in the artist's rendering.
