If you are already pretty close to powder I'd say you've gone far enough. I'd guess your efficiency issues lie somewhere else...I am tired of 60% efficiency. I have been adjusting my mill and i feel like I am pretty close to powder. I understand that I could probably keep going, but a stuck sparge drives me nuts and I would like to be able to avoid using rice hulls. I have a crankandstein with 2 rollers, does anyone have an actual measurment on the gap that works well without getting a stuck sparge or is this a scenario where I am better off with trial and error?

+1.I get at LEAST 75% and last batch got 87% and I have the LHBS crush my grains. Look elsewhere. Good luck.If you are already pretty close to powder I'd say you've gone far enough. I'd guess your efficiency issues lie somewhere else...

Have you checked the gap? If it's significantly less than .039, then you're just headed in the wrong direction. Do you have a feeler gauge?Thanks guys. I think this sunday I am going to try and close the gap even more and at least there will be no doubt its the crush...any other substitutes if I do get a stuck sparge if I have no rice hulls and cant make it to the LHBS? Could I throw in some whole barley if needed?

Mine's (JSP) been at .025" for a long time. Of course roller speed and how grain is fed make a big difference.Have you checked the gap? If it's significantly less than .039, then you're just headed in the wrong direction. Do you have a feeler gauge?

That's what I was thinking...If you are already pretty close to powder I'd say you've gone far enough. I'd guess your efficiency issues lie somewhere else...

it certainly would.Are you keeping your mash pH in line? pH will effect efficiency as well.

OMG, what the hell are you doing!!! OK, so maybe it doesn't have to be exactly 0.039". It's very true that roller speed/feeding also make a difference, though, unless your mill is motorized that's a little tough to control.Mine's (JSP) been at .025" for a long time. Of course roller speed and how grain is fed make a big difference.
If you don't mind making the trip up to Leominster you're welcome to swing by to do a comparison with my mill. I'm getting 80-90% efficiency with my crush, so at least you'd have something you know is decent to compare it to.I havent checked with a feeler gauge yet, but I do have some and will verify the exact gap. The speed is the next culprit (mill wise) I can think of, I finally have a better drill to slow down the speed which might let the rollers chew on the grain a bit more, but all things aside the texture from a visual standpoint and from holding in my hand feels like the grain is pretty crushed up, but I am not one for making assumptions so I will check with a feeler gauge and see how I make out.
