With all the great features of the already popular MM-2, and the addition of a third roller, you'll be able to achieve the best crush around, at a higher throughput speed. The MM-3 crushes all your grain twice, with one pass through the mill. It starts with a preliminary crush through the initial fixed gap between the top two rollers, and then ends with a pass through the second gap between the drive roller, and the bottom third roller. The initial pass slightly flattens the grain, and gets it ready for the next crush, that breaks apart the grains and loosens the starch with minimal husk damage.
The MM-3 consists of a 6061 aluminum block frame with three 6" long steel rollers riding on SAE 841 oil impregnated bronze bushings. They use a superior grade of steel that is much harder than what is found on most comparable products and should last almost twice as long. The drive shaft, and all the axles are integral to the roller rather than screwed into the ends. This makes it fine to drive the mill clockwise, or counter-clockwise. All the axles are 3/8", with minimal freeplay in the bushings. With 20% more roller surface area than brand "C", you'll get more throughput with the same drive speed, in either direction!
One knurled steel roller is driven by a standard electric drill (not included) to feed the grain through the initial fixed gap of approximately .060", and then through the adjustable secondary gap and crush the grist. Both ends of the non-driven top idler roller ride in bronze bushings that are pressed into the frames, while the second idler roller rides in bushings that are offset mounted in an adjustable knob. The knob is held in a fixed position by a set-screw that you can loosen to adjust the mill. This system provides an adjustment range of .065". The knobs are made from 303 stainless steel for excellent durability, and are larger in diameter than the competition, as well as knurled for a positive grip. They've also added a groove in the newest design knobs with a matching rounded head on the thumbscrew that allows for a much better grip on the knob to avoid gap changes while milling, and also providing knob retention.
If you don't purchase the base and hopper, you will need to fabricate one to feed the grist through the mill. The mill can be mounted above or below the base and attached using the included mounting bolts. You'll also need a high quality corded drill to drive this beast. We recommend a 1/2" drive Dewalt or comparable drill. Please note that the larger shaft option requires the larger 1/2" drive drill, as the more common 3/8" chuck won't accommodate the larger shaft.
