Now that I’m up to brewing 8-10 batches a year, I think it’s finally time to bite the bullet and get my own grain mill. I do mainly BIAB 5 gallon batches.

Should I splurge for the 3 roller or will a 2 roller suffice? Which brands are high quality and which should I steer away from? Anything else I should seek out or avoid?

Thanks!!! 🍻
 

MaltMuncher Grain Mill 3 Roller works great for me, I had the 2 mill it was fine for years but whatever i did to it. It wont hold a proper gap anymore. I think the 3 mill is probably worth the little extra cash for milling really fine for BIAB. My efficiency is around 82ish%. You could just run it threw the 2mill twice though if money matters more than time.

 
No need to really overthink it. I'm going on 12 years with my Corona mill, and it's seen 400+lbs/ year for the last five years.
Yep! I have only ever used a Corona. Couldn’t say how much grain I have put through it, but in the hundreds of pounds. Heck, I’ve probably ground 100 lbs of whole corn for my chickens! 🐓
I did recently pick up a motorized two-roller mill in a Craigslist bulk buy. I will eventually give it a try. I may even ditch the hand drill and go back to hand cranking the Corona. It just feels more like “making beer” when I hand mill the grain. But what do I know; I like heating my water on a wood stove. 😜
 
Corona's are sturdy and do the job, used one back in the '90s and still have it. Though I found it hard to get optimal crush without grinding up the hulls more than wanted. Then got a two roller, (BC) on which rollers wore out after 50 or so 20# crushes.

Am very happy with three roller Kegland, over 100 batches so far. Fairly inexpensive and easier to adjust and better feed than two roller. Using a variable speed drill that is powerful enough to go slow works well enough for me, though I'm sure the gear drive ones are nice if one wants to spend more.

I'd advise to avoid Barley Crusher, rollers not hardened enough hold up, then it stops feeding.

I've been eyeballing that for 3 months now. Is it a lot faster than the 2 roll? I don't NEED another mill, but my current one is patched up a bit...
 
I think my Corona style mill was about $20 and now I see them on Amazon for $17. The OP is planning to BIAB. Corona mills are well suited to that as it doesn't matter if the hulls are shredded or if the particles are smaller. Smaller is better as faster and more complete conversion is achieved and the bag is the filter so there is no reliance on the intact husks.

The difference between the cost of the Corona mill and the Malt Muncher will buy a lot of ingredients and it is ingredients that make beer, not the mill.

I use a Corona as well, but do a conventional mash. When I started out this way, I had a great fear of a stuck mash. However, I brewed for several years this way before it eventually happened. Then, all I did was stuck my long spoon in a couple places and the flow returned; no problems. I’m likely running a little finer than a typical crush, but I have not missed a target OG.
I use a regular false bottom in my mash tun, and have not had a problem with fines coming through, but have wondered if anyone has ever used a bag in the mash tun in the same manner as the BIAB, but just for filtering and lifting for additional drainage.
 
Yup. This is the image of my next mill - if I ever need a "next mill" 😁

Suhweet!

I have the morebeer Mighty Mill 3 roller as well, and love it. I've had two others (off brand and one a friend gave me) that were two-rollers; both were lackluster. The thing I like most about the geared 3-roller is I can dump the grain in the hopper before starting the drill (most days, sometimes it's squiffy and won't do it) and it will take off.
 
My wife bought me mine for Xmas or my birthday. I would probably have not bought new, but she did. It is a 2 roller and it instantly made a huge difference in my efficiency. Going back, for those who remember, the guy who gave me literally all his beer equipment had a really cool 2 roller that he put a motor on and made a base for it to fit over a bucket. It was huge and I had no room, but now I wish I would have taken it just because it looked so cool. I am going to have to see how he is doing, really a hell of a nice guy. Anyway, off thread, but for me I look at the used market now as there is tons of stuff people are almost giving away simply because they don't brew any more.
 
I had an OG single side MaltMill...then I bought a double sided adjustable MaltMill....then their 'factory' burnt down.

I need to do both grain and corn....what are my options? I don't care if it's 2 roller or 3. I won't say money isn't an object because I won't pay for a pro-sized rig with an included motor. But just the mill itself, I've motorized multiple and I already have a 1HP motor on my current one.
 
[edit] Crankandstein sells roller mills they support for corn (frankly I was surprised).
That said the cost effective bet might be a Corona mill dedicated to corn and a roller mill for malted barley/wheat/oats/rye/etc...

Cheers!

I have been using my corona mill for both grinding corn for the chickens and grinding my grain for brewing. I used to just hand crank it, but as I moved to larger batches, I have come to appreciate using my cordless drill to power it.
 
In the "Buy it once, only cry once" genre of brewing equipment, I am so glad I bought the newly released Spike mill. It replaced a three roller, drill driven setup and does a much more consistent and easier job. My efficiency went up slightly, but more importantly to me, the efficiency I am getting is now much more consistent and recirc while mashing and draining the grist (Brewzilla 65L Gen4) after mashing results in a noticeably higher flow. Spike has some great videos showing the engineering behind the mill; they put a ton of thought into the design. It's built so darned well that I am betting it is the last mill I will ever buy.

Well worth the $$$s in my opinion.
 
What do you drive it with? The American Ale Works motor I was thinking of apparently is no longer available - their site is deadski along with their FB page :(

My heretofore well loved Cereal Killer has been slipping the idle roller lately and my thoughts have been drifting to the Crankandstein 320G for the 2" rollers. No way that's going to be driven by my 42 inch-pound gear motor though :oops:

Cheers!
 
I use a Monster Mill Pro 3 roller with a corded drill for my 15gal Spike pilot system. Before that, I was using my personal Monster Mill 2 roller. That thing was an absolute beast. I must have put close to 10,000lbs of grain through it before it wouldn't bite any more.

Yeah, I got the 1/2 HP American Ale Works motor (160RPM I believe) to run it shortly after getting it. I was sad to see that they were no longer in business. Trying to use a drill was just too hard to dial in any consistent low speed, well for me it was anyways. Others have success with cordless drills. Lol. I'm not sure 42in/lbs will run it, I'll have to check the actual torque rating on my motor when i get back in town.

The actual gears are what makes this thing so great - nothing really stops it. Full hopper starts up and runs through without any issue or any slipping. By far the easiest and most trouble free part of my brew day.
