Do you want to motorize your Two Roller Milll? This high torque geared grain mill motor fits the 10mm diameter shaft on our item L07 and B21 Two Roller Mills, and many other other 2 or three roller mill with a 10mm diameter drive shaft including some BarleyCrusher and Cereal Killer mills (but not all, check your shaft diameter before ordering). It 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.
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 mill with a 10mm drive shaft, you will need to wire this mill to your 110 volt power source (a plug is not included). Note the coupler can be modified with a hacksaw or grinder (see picture at right) to also accept narrower 3/8" (9.5mm) drive shaft mills. You will also need to build a table mount for this mill, and elevate the mill on a base you fabricate to align the mill drive shaft with the motor shaft. 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.

I picked up a mill super cheap several years ago, and have always ran it with a Harbor Freight drill. After seeing an article at Homebrewtalk.com on motorizing a malt mill with a direct drive motor - ie: no belts, pulleys or gear boxes, I started looking for a "package deal" - motor, motor mount, spider coupling, safety switch - and found this great deal at Williams. The installation instructions were a snap, and the modification on the spider coupling (using a vice and a hacksaw to reduce the mill-side coupling to a smaller diameter) worked perfectly. Using washers as shims under the motor mount worked perfectly to align the two shafts horizontally, and now milling my grain is a joy! With a more consistent slower speed, the shredding of the husks is greatly reduced, so much so that it initially looked like I was getting whole kernels going through, but when I checked, found just empty husks!
This kit is a good way to motorize your mill without having to buy separate parts. I was able to adapt it to my JSP Malt Mill using a brass sleeve which had a 10 mm outside diameter. I used 1/8" aluminum shims to raise the mill to the correct level to match the motor.
I mounted this on a piece of 1/2 inch oak plywood. It turns at the perfect speed of 180 RPM with plenty of torque and does not bog down. Why work up a sweat, it gets hot enough while brewing. I would definitely recommend this kit!
Received it and had it assembled within a couple hours. I brewed the following day and can't describe how nice it was to not have to use my cordless drill. Set it up on a pair of buckets, loaded it with grain and proceeded to prep the rest of my brew day stuff.
I'd been searching for a gear motor for my Cereal Killer grain mill for some time. The problem I was having was locating a gear drive motor that was the correct speed, voltage and shaft size at a reasonable price. Then I would need to source a coupler and some type of switch. When I received the email from Williams Brewing they had a complete kit and it was a great price I snapped it up! I assembled it this weekend. I haven't crushed any grain yet but it does run well and I have no reason to believe it won't meet or exceed my expectations. I'm very pleased with this purchase and I'd recommend it to anyone looking to motorize their grain mill.
9.75" from the end of the motor housing to the end of the coupler.
The shaft from the gearbox of the motor is 12mm, and the coupler included with this kit reduces the mill side shaft to 10mm. A 3/8" shaft is 9.5mm, so you will need to hacksaw the coupler as shown in the product description page a bit to make it fit. We do not yet have a 9.5mm (3/8") coupler.
Facing the shaft, it rotates counter-clockwise.
To adapt the aluminum spider coupler included with this kit, you will need to remove the clamping screws and hacksaw the opening to make it wider. This requires a vise and a good hacksaw, but is not hard.
