This three roller mill with aluminum hopper holds 12 pounds of malted barley, and features three 6" by 1½" knurled rollers turning in precisely machined ball bearings. Three rollers crush grain more thoroughly and evenly than a two roller mill for the most extract per pound of grain. Figure running 8 to 12 pounds per minute through this mill depending on its source of power.
Rollers are gap-adjustable at both ends and calibrations are included at both ends for easily repeatable gap settings. Gap can be set from 0 to .63", we recommend you start with .63" to see how your mill works, and then narrow the gap to .50" or so if you find any whole kernels coming through.
The steel rollers are machined to efficently grab the kernels and pull them through the mill. The detachable handcrank can be removed to install a 1/2" shaft capable electric drill (we recommend a good quality variable speed corded drill, as this mill requires some force to turn quickly, and a cheap drill will not work well).
Assembly required, you will need to screw the hopper together with the included machine screws and screw the base to your mounting board (mounting board and mounting screws are not included, but screw holes are provided in the base for mounting).
Note: For use with malted barley only, not for use with corn.

I was a bit perplexed when this arrived in a heavy, tiny box. i opened it up and was greeted with easy to follow instructions for assembly, after 20 minutes I was on my way. Combined with a heavy duty, high torque drill this bad boy is now crushing grains like nobody's business. Smooth, easy, powerful, I highly recommend the three roller grain mill.
Start at .063 for your first crush, and see if all the kernels are crushed. If some are still whole passing through, drop it down between .063 and .032 evenly on both sides. The idea is to have it as wide open as possible while still crushing every kernel (which depends on kernel size).
If your idler rollers are freezing up, it could be grain dust that has been sitting in the gaps at the end of the rollers that gets hard with humidity. Try a hot water rinse on the sticky rollers to get rid of the grain dust deposits.
