In theory the rod mill was more efficient than a ball mill, which was more efficient than stamp mills...In practice rod mills didnt work as well, at least the models that were used in sw Oregon: One rod mill near Jacksonville Or only last two weeks before the management junked it. Another near Cave Junction could only handle a ton or two a day of ore, even though it was "rated at 25 tons, and this mill never did much. In an interview during the 1950's the owner reported that only a couple thousand dollars of ore was removed.
