I sell brass on the side. I run anywhere from a half to a full five gallon bucket at a time. I use cement mixers for tumblers. Doing the wet tumbling isn't the issue for me. It's the drying that I would have to conquer.
Jerry Miculek has a video on drying mass quantities of brass. Well, actually the video is on how his entire wet tumbling process, but it's the drying part that's of particular interest.
He made some large frames out of 2x4's, then mounted wire mesh in the frames. He then leaves the brass filled frames out in the sun. He has to deal with extremely high humidity there in Louisiana, but even so, he's able to get them dry no problem.
I did give the used dryer sheets a try, and yeah.. that's a huge help.
But the F.A.R.T., when used with their wet media separator, is a pleasure to use. I also use their case dryer. It's extremely dry where I live, so my cases are dry in an hour.
I'm so happy with my new wet tumbling setup that I'll never go back to dry tumbling.
