1. Add a Sieve that uses your wheels to move the sieve in like an up and down graphic if thats possible.
2. Add an automatic hammering device or a crushing machine kind of like one of those turning mills they used to crush wheat with.
3. Maybe if you wanted or had the spare time add stuff like compressed stuff.

Ex Compressum is 1.12.x as I use it currently. And no, Ex Compressum does not have it, Ex Astris most likely does, and that is not updated last I checked.

Edit: Creatio does in fact have it, and so this suggestion in particular is redundant. Others are filled by Ex Compressum, which has an auto hammer and auto sieve which take RF, as well as a heavy sieve and compressed blocks.

Does not have what?

Ex Compressum doesn't have those mechanical wheels for automating sieves, you know, with the water wheel and stuff?

That's what Ex Compressum and Ex Astris do.
However neither have been ported to 1.12 afaik.

They haven't been ported because there was no 1.12 version of exNihilo till now.
