Motor For A Mill

[Back Yard Brewer]

Can someone link me to a thread or two on what motors brewers have used and pics on their set-ups. Have bought a millmaster some time ago and its about time I got my **** together and set it up. From what I have read so far I would need a minnimum of a 1hp / .75kw motor. Better still if there are brewers out there who can pm me on what they have done. Specifically info on the millmaster would be better.

Cheers

Mate,

I am on my way up to the shed to finish the hopper on my new mashmaster.
Using the same motor as was used on the marga. It is a third hp I think with a
2 inch pulley driving an 18 inch pulley.
Let you know later if it is strong enough. I am sure it will be if it can be run with a drill.

Cheers,
Bud

Here is my version of it http://www.aussiehomebrewer.com/forum/inde...showtopic=17799

I used one of these, but I think they've been out of stock for some time now.

Good info there John.

The only other thing you'd need is a 12V supply of sorts.

You only need 1/4 to 1/2 horsepower but it will need to be reduced right down with either pulleys or a gear box. My motor is 1/4hp reduced to 102 rpm. It still doesnt like it when grain gets it the gears(major design flaw), id prob go 1/2 hp with a 12 inch pulley and as small a pulley as possible on the motor shaft. You may find a 1hp motor isnt much dearer if you get lucky at a scrap yard.

Thanks Stubbie,

For all my 12v supply needs I use an old PC power supply, get them for $5 from the tip-shop and about $10 of stuff from Jaycar (switches, post, resistor) is all you need to convert it. They give upto 15 amps, which is a ton of power for crushing.

A 12v powersupply from Jaycar or something like that is very expensive if you want decent amperage out of it.

If anyone is looking for 12v supply, I have some available rated at 10.83A. $25.

Do you run a millmaster?

Im in the same position. Ive had a millmaster since the preorder. 2 years?

Today I have finally had a pulley sleeved to fit the 12mm shaft. So now I have a pulley mounted on the mill.

I bought a 1/4hp motor about 6-12 months ago to drive it. Its off a bench drill & has a multi step pulley. Hopefully will find some time over the weekend to rig it up finally.

Got my Millmaster setup & gave it its 1st run on the weekend. Very happy with the result.

Short clip of it in action -

Congratulations. I hope to be there soon. Still mapping my Washing Machine motor then map the motor output RPM. Then its thinking about transmission time, though I'm still leaning towards a large pulley wheel on the mill and vbelt.


Your crush speed would make the LHBS jealous as his non MashMaster MillMaster takes quite a while to get through 5 kilos. We had time for a beer, well most of a beer


I wonder if anyone has heard from Ross about if there is a new hopper with gear guard and if so, when its due. I may have to ring him up.

Cheers,
Brewer Pete

Great video. How about some techy stuff? A look at how you have the motor mounted and the size of the pulleys would also be great. Currently have a 1hp and 1/2hp motor available + a 2" pulley that will fit either motor. Will most likely go the 1/2hp so that the pulley sizes won't need to be that large on the mill.

I bought this 3/4hp 920rpm cap start motor, and got a 1.25" pulley for the motor and 10" custom bored and keyed pulley and maching belt from these guys for another $80. Some dodgy carpentry later and I knocked up a small bench to mount it all on which can be seen here.

Yeah, will get some pics on the weekend. Its built to mount on the end of my brew stand so is a bit awkward to photograph off.
Its a 1/4hp motor off a drill press & retains its multi step pulley. Ebay score for about 20 bux. It was running off the smallest which is about 1" & the mill pulley is 12".

 

[KillerRx4]

Pics as promised...

I built the mill frame at the same time as my brewery stand & decided to incorporate it so I can hang it off the end when i need to mill grain, then pack it away in the shed corner when not in use.

Mill Mounted

Mill Unmounted

Motor is 240v 4 pole 3/4HP 1420rpm.
The motor mount incorporates a slide mount to set the horizontal position to align the step pulley and a vertical slide mount for belt tension.
Motor mount - Front side

Motor mount - Rear side

Chute is just a bit of off cut gal channel, i duct taped the surface the grain comes in contact with & used some hose to cover the edges.
It kinda looks rusty in the pic but thats just dust from running some dark malt through it.
Grain Chute

The mill pulley is 12" A section, the smallest end of the motor pulley is 1" but the way the belt rides up in it its probably more like 1.5-2"

I guess if you no-chill putting a mill on a brewstand is probably safe. But I use a chiller and there is no way I would lay a blanket of lactic across gear that is going to be in contact with chilled wort at the end of the process. You may be lucky, and it may work out, but why take the risk if you dont need to.
