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 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). You will need 4 M6 by 20 machine screws (not included) to mount this to the optional base.
Note: For use with malted barley only, not for use with corn.
