Crankandstein has been in production for over fifteen years, specializing in equipment on a scale to get your business or hobby rolling.
As originator of the three-roller configuration for use in beer and chocolate production, these mills are the most advanced in their class. The rollers turn with less friction, which makes the feed more reliable, reduces wear on the knurled surfaces and bearings, and produces a better husk particle for more efficient sparging or winnowing.
Having a Crankandstein makes a real difference.
The plain steel of the Crankandstein rollers knurls and reknurls more precisely and is tougher than the higher carbon steel of some competitors. While the competition may claim greater longevity based on theory, in a lifetime of actual use these mills are subject to foreign material that gouges the roller surfaces. With the brittle high carbon steel used by other brands, the diamond pattern is more easily chipped away and less likely to reknurl back to the original diameter. Further hardening of the steel only makes this long-term deterioration worse. Our mills are designed for maximum life spans and economical refurbishing.
Here are some links to plans for setting up a mill with an electric drill or motor:
A 12" mill pulley and a 1.5" motor pulley gets a 1725 rpm motor down around 200 rpm on the mill. 1/4 hp should do it for the homebrewing mills. 1/2 hp works for the 320D mill and 3/4 hp for the 328D. Ebay has some good deals on motors. Grainger has a good selection of pulleys. The 12" x 1/2" bore 3x938, 1.5" x 1/2" bore 3x892, 1.5" x 5/8" is 3x893. These fit v-belts 3L, 4L and A. Having the 1/2" driveshaft or the 3/8" to 1/2" adapter gives you the right diameter and clearance for attaching the mill pulley. Or put a 3/8" ID, 1/2" OD bushing in the pulley bore.
Here's a gear motor reasonably priced that turns a nice slow speed:
