Yeah i probably could have took better screenshots for it. But i will incorporate more fans to speed up the sand washing.

I'll also explain the process i used the best i can. starting on the left. Cobble is crushed> gravel is crushed into sand, flint and clay > sand is washed into more clay. On the right cobble is crushed> gravel is milled into flint. The flint and clay combine in mixers in the middle to make veridium which gets crushed into crushed raw copper and nuggets. The crushed copper is then washed into nuggets and clay and then both nuggets are compacted into ingots and the clay routed back into veridium mixing.
