Hey guys, Just used my MM-2 mill for the 1 st time. I left it set @ .045, as came and suggested by the MFG.

Tried to take as "REAL" pics as I could. I read that the gap can be as tight as .036-7 . Im thinking my crush has a lot of powder? Oh maybe it's just right?

What do you Experts think?



I have in here:
7 Lbs Pale Ale 2 row
3/4 Lb Cara/Pils
1/2 Lb C-20
1/2 Lb Vienna

I was told by LHBS The Cara/Pils is a very HARD grain, Mix it with other grain to crush.?

That looks like a fairly decent crush. Definitely not too fine. The crush I use is a little more fine than that and I've not had any kind of issues. Brewing with it will be the true test so you can see what level of efficiency you're getting and then can decide if you need to go tighter or if you're happy with where it's at now. Some people like to chase a really high efficiency number, however I'm happy sitting right around 70%. I think that's more personal preference than anything.

As for the Carapils that stuff is pretty hard. Take a kernel of pale and chew it, then the carapils and you'll see it's almost like chewing on a rock. I mill all my grains together at the same time and there haven't been any issues. Never tried to mill the Carapils separately so I couldn't say how the rollers would handle it.

My crush is set to 0.35. From the pics you could definitely go tighter. The manufacturer recommends that wide gap for the sake of having customers avoid stuck sparges and complain. It will take a bit of messing around but everyone's system is different. I would tighten it up a bit at a time and if you get a stuck sparge then dial back.

I've had my MM2 for awhile now and started off with a setting at 0.035 and then went to 0.032 and now I'm at 0.030. I've been at 0.030 for the last couple - I haven't had any stuck sparges but a few have definitely been slow. But my efficiencies have been great!

My crush looks pretty close to that and I have the MM2 also.



Mine is at the setting from the factory or pretty darn close.
No stuck sparges and I am hitting my Brewsmith numbers dead on with 75% efficiency.

Looks good to me.

I feel that crush should be set as tight as possible without compromising husk integrity. Your husks look good.

Your lautering system will also influence how fine you can go.

Another vote for 0.032. Like you, I started out with my MM2 around .045 but found my efficiency was about 60%. Made my crush a little finer and today I hit my targets bang on. I was aiming for around 72%

Sorry, to rehash an old thread. I just used my MM2 for the first time at the factory standard 0.045", and I got 60% efficiency. Really, irritated me because I undershot my target SG by 7 points. Either way, I tried setting the MM2 to 0.035", but I had a hard time getting my cordless drill to crush the grain. I'm guessing I'm going to have to go out and buy a corded drill. Are you guys using gaps less than 0.040" using a corded drill/motor to spin the mills?

Thanks in advance.
