Unfortunately I havent had time for much modelling these days, but thought Id share a few pics of a  1/4" scale Depression era mill in southwestern Oregon I did for an architecture class. The prototype was built largely of locally available materials, like peeled logs and large western red cedar shakes. Similar to ball mills that largely replaced stamp mills , this circa 1933 rod mill used a large rotating cylinder with rods in it to crush the gold ore, before it was sent to two Wifley tables and finally to flotation tank. This mill recently collapsed, but enough remains to take a few measurements and make a reasonable model:
