PLEASE NOTE: We are closed through March and will not be taking payments and orders at this time.
Crankandstein has been in production for over fifteen years and we look forward to more features, new models and increased production later this year.
As originator of the configuration for use in homebrewing, the 3-roller D series mills are the most advanced in their class.
Having a Crankandstein makes a real difference.
There are more features incorporated into Crankandsteins than the competition realizes. I hesitate to list them all since they're basically trade secrets that come from years of experience and feedback.
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.
Higher efficiency can result in better beer by getting more sugar out with less runoff. Also, the 3rd rollers have a smoother surface further preserving husk integrity.
The plain steel of the Crankandstein rollers knurls 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, 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.
Here are some links to plans for setting up a mill with an electric drill or motor:
A 10"-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. A 10"-12" mill pulley and a 1.5" motor pulley gets a 1725 rpm motor down around 200 rpm on the mill. 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 10" x 1/2" bore is # 3x934, 12" x 1/2" bore 3x938, 1.5" x 1/2" bore 3x892, 1.5" x 5/8" is 3x893, 2" x 1/2" bore 3x895, 2" x 5/8" bore 3x896. 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.
