Product Details

Introducing the newest version of our awesome 2-roller Pro series Monster Mill, the MM2-Pro PD. This mill is meant to be driven with a belt and pulley system, and is an upgrade to our MM-2Pro mill that adds a 3/4" diameter, 3.5" long drive shaft with a key way.  The shaft also includes a machined 5/8" hex at the very end so that you can drive the mill with a mating socket, and your drill until you acquire a motor and drive system.  We have also added a thicker drive side frame that includes a USA made sealed roller bearing to handle the side loads generated by the belt tension in a pulley drive setup.  All the great features of the 2Pro designed to be belt driven with pulleys and a motor.  This mill as supplied is not compatible with a coupler for direct drive using our gearmotor.

All pulley drive mills come standard with heat treated Rollers for 10X the life of our standard steel.  The MM-2Pro PD consists of a 6061 aluminum block frame with two 6" long, and 2" diameter steel rollers riding on SAE 841 oil impregnated bronze bushings, and a sealed USA made rollerl bearing on the drive shaft. We use a superior grade of heat treated 1144 steel that is much much harder than what is found on any comparable products and should last almost ten times as as long as our standard steel. 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, and a much larger 3/4" drive shaft with a key way comes standard. The larger 2" diameter rollers allow a finer crush with more minimal husk damage, and milling at smaller gap settings without worry of skipping. This mill also comes with a much larger gap adjustment range of .160", more than double our standard range that should allow you to mill other grains like corn, as well as the conventional grist bills with barley.

One of the knurled steel rollers is driven by a pulley (not included) with 3/4" bore and standard 3/16" key way to feed the grain through the adjustable gap and crush the grist. Make sure you have at least a 1 hp electric motor at 1725 rpm or slower, and the required 10:1 speed reduction pulley set to drive this mill, we can't be responsible for motor death! : )  Both ends of the non-driven roller ride in bushings that are offset mounted in an adjustable knob. The billet knob is held in a fixed position by a black oxide bolt you can loosen to adjust the mill. This system provides an adjustment range of .160". Our new design knobs are milled from solid 6061 aluminum barstock for excellent durability. The flange has two semi-circular slots that allow you to attach the knob positively to the face of the aluminum frame. They have 12 sides for a positive grip. You need to purchase our base and hopper (guaranteed to save you way more than $45 of your time and materials) or fabricate your own to feed the grist through the mill. The mill can be mounted above or below the base and attached using the included mounting bolts.

There is ONE material option available for the larger 2" pulley drive mills. They only come standard with our 1144 steel rollers that have been heat treated/hardened. The regular 1144 alloy rollers are heat treated to approximately 51-54 Rockwell C hardness.  This roller material has survived through more than 200,000 lbs of grist in commercial applications.  Plain steel mills kept indoors, and used regularly won't have rust issues. Non climate controlled areas, or minimal usage could see some corrosion come up that is easily removed with a wire brush. We recommend this mill with our HEAT TREATED steel rollers for all COMMERCIAL applications.  This mill WILL mill corn, and works just fine with rye by itself.  It is also designed for barley and wheat malt, and un-malted wheat.
