This large, 12 pound hand cranked mill is quick and easy for grinding corn. In only 5 minutes, it converted the 3 cups of whole corn in the hopper to a moderately course cornmeal in a single pass. That is faster than my grain mill attachment for the Kitchen Aid mixer! In my smaller hand mills like my favorite, the PORKERT, I make more than one pass to keep the effort to crank the hand mills reasonable. No need to do that with this large mill, and it is easier to crank in one single pass than any of my other hand mills. It will not make fine flour though. If you are growing mostly corn this is the easiest and quickest mill to make cornmeal with.
