Do you want to motorize your KegLand MaltMuncher Mill? This high torque geared grain mill motor fits the 12mm shaft on our item B06 Three Roller Mill (and any other 2 or three roller mill with a 12mm drive shaft and 1½" diameter rollers), and features internal gears to spin your mill at 200 rpm. A heavy duty spider coupling absorbs the direct drive shock, and the 1 amp motor has plenty of power to turn. This kit also includes a 10mm shaft adapter, in case you have a Maltmuncher Two Roller Mill.

NOTE: This is for mills with 1½" diameter rollers only, it will not drive larger mills with 2" diameter rollers. This will not work with the Monster Mill MM3

A safety switch is included for mounting on your mill mount. This includes a button that is harder to turn on than turn off (to turn on, twist the red knob and press down, to turn off, just press the red knob).

This kit requires wiring and installation, besides a MaltMuncher Mill, you will need to wire this mill to your 110 volt power source (a plug is not included). You will also need to build a table mount for this mill, and elevate the motor ½" so it will line up with the drive shaft on the Mill.

See the thumbnails for mounting and wiring ideas.. When wiring, besides the hot red and black neutral wires coming out of the safety switch that you wire to your house 110 volt hot and neutral lines, you will also need to wire a green ground wire from a mount on the motor to your three prong plug.

For barley malt only, this mill does not crush corn.

Crankandstein 2d + Maltmuncher grain mill motorizing kit

Review by James Lawrence Mueller on 11/12/2020

I was happy to find that this motor worked with the second hand Crankandstein 2d and base it came attached to. All I needed was a 3/8" jaw coupling hub from Grainger to attach to the smaller diameter driveshaft on the mill. I also raised the mill a few eights of an inch with some plywood so the driveshafts of the mill and motor were at the same height. The power button was easy enough to wire-up. I've only had a chance to crush one batch of grain so far but my days of wrestling a drill are over. I think it was well worth the investment.

Nice product, great service

Review by Peter on 3/10/2020

Nice kit with all the parts you need for certain mills. As it states, it connects to a 10 or 12mm drive shaft. I have a Monster Mill with a 3/8 inch shaft, so had to get a different spider gear*. No problem. Got it all hooked up and working. When I first got it going the motor was under powered. I posted a review here with a poor rating. I got an email from Williams the next day to find out more. They thought I might have a faulty motor and sent out a replacement, which I had in a couple of days. Upon installing it, everything works great! It mills up grain easily and quickly, even when i threw some rye at it. *for reference, I used a TB Woods L050 spider I got from Grainger. This consists of: Jaw Coupling Hub, 12mm, Sintered Iron Jaw Coupling Hub, 3/8", Sintered Iron Jaw Coupling Insert, Buna N, L050

Big Help

Review by Clem on 7/5/2018

I'm old and I didn't like grinding my malt using a drill I had a hook up problem which Williams solved for me have only used it once but it works great.

awesome kit

Review by Michael Harper on 11/20/2017

I also bought the triple roller grain mill with this. I built a small table with casters and mounted both on it. The wood that I used was just a bit over 1.25", so instead of shimming the motor mount, I just sanded the wood down to the perfect height. I used it the first time this weekend and it was obvious that I got a better crush than at my LHBS and it was all so easy to put together.

Motor doesn't fit mill

Review by Justin on 7/22/2017

The level of the motor is not level with the mill. I had to use a router to lower the base where the motor sits so that it aligned with the mill. The photo on the website are deceiving. That being said, the kit works like a charm and I'm very happy.

Q: What is the torque of the motor? Will it power a geared three roller mill?

A: We do not have torque figures, but a geared mill would take more power than the 3 roller MaltMuncher this was designed around. So we think there is a good chance it would not have enough power to run a geared three roller mill.

Q: Will this work without modification on a Barley Crusher Maltmill Model 50125A?

A: Yes, although you may need to buy a different spider coupler to fit the narrower drive shaft of the Barley Crusher.

Q: What’s decibel level of this motor?

A: We don't have a decibel meter but it is quieter than a garbage disposal, and a bit noisier than a dishwasher.

Q: What are the dimensions of the motor?

A: 3.5" wide, 4.5" wide with included mounting bracket. 10" long with shaft, 8.5" long if you do not count the shaft.

Q: Couple of questions. 1. Do you have a recommended source for the power cord? 2. Will this fit the malt muncher without any additional couplers?

A: We used an old computer power cord when wiring ours. This will fit the I13 Three Roller Malt Muncher without any additional couplers, although you will need to fabricate a base.
