* Rock mill
  * Earlygame post-steel crusher type machine
  * Can grind down various stones, gravel and sand into finer items while yielding byproduct
  * Mainly intended to serve as an easy way to automate/bulk craft certain elements in earlygame before BOP
  * While the byproduct chances are rather low and the recipe times are slow, the mills are easily scalable due to their low cost
  * Comes with convenient stacking frame
  * Ideal for skyblock/seablock type challenge runs, as it can be configured to serve as an Ex Nihilo substitute
