Space Chimp

After a lot of science and funds stockpiling through probe missions and my first test colony on Minmus, I was planning my first self-supporting colony farther from Kerbin but couldn't find means of extracting and converting materials into fertilizer. The MKS wiki says to use regolith sifters or Crush-O-Matics, but I can't find either in the science tree. I also can't find the refineries in there either. I have downloaded every USI/MKS expansion in ckan. Is there a download I'm missing? I'm enjoying the mod so far, and I'd hate to have to switch now.
