What I'm trying to do, is putting some Uranium Ore into a Macerator to produces Crushed Uranium Ore which then should be automatically ejected into the Ore Washing Plant (works fine). After washing, the Purified Uranium Ore should be automatically ejected into the Thermal Centrifuge and the Stone Dust + Tiny Pile of Lead Dust should be ejected into a chest for later use. The problem here is, that no matter how I try it, I can't get the Ore Washing Plant to eject anything. I tried it with an eject and advanced eject upgrade. I tried a pulling upgrade for the Centrifuge and since I'm using buildcraft I also tried to use extraction pipes, normal pipes and what-not pipes, tho nothing seems to work.
If I would be good enough to get this too work, I also tried that the Centrifuge (when done) should eject both uranium items into a chest but this didn't work either. So far I tried my a*s off to get it to work, but somehow it wont so it would be really cool if someone could helm me with that
