I ran into something that kind of threw my mind for a bit of a loop while setting up my Extractor system, coal. After going through the Extractor, the coal ore gets turned into coal flakes. OK, makes sense. But then you smelt the flakes to get coal. That didn't really make much sense to me. Then I got to thinking, maybe have something that takes the coal flakes and compresses it into coal? Then I remembered the Compactor, but it takes coal and eventually turns it into diamonds. Maybe how about an alternate mode that has lower requirements and turns the flakes into coal?
Sorry if this is a weird suggestion, it's just that I find it odd that you smelt a pile coal bits to get a coal chunk. Metals and the like sure, but not coal. I can understand why it's like this though, a lot easier to just mass code "flakes -> smelt -> final product". This could also be used for maybe other types of flakes as well. It would give more use to the Compactor.
