65% efficiency with corona mill how many more turns?

[Beer_Eugenics]

My first go with a corona mill I hit 65% efficiency. My question is how many more turns should I go, ¼ ½ I would be happy with 75%? This thing worked great right out of the box too.

Are you sparging with a manifold? BIAB? It depends on your method as to how fine you want to go.

It could also depend on your water chemistry/mash pH

Batch Sparge with Bazooka.

You don't want flour, so just keep your eye on it

He doesn't want all flour, but he certainly wants some flour in there.

 

[tre9er]

Not mostly flour its what I meant

I believe for every 1/8 turn you will gain approx. 2% efficiency, so if you are looking for a 10% gain, that would be 1 1/4 turns...

I have absolutely no idea! The reply above is in jest...turn it without fear...it's only beer...examine the crush, and the mill plates how wide, as that should be your guide

and don't fear some flour, it's unlikely, and relieving a stuck sparge might only cost you and hour

Go ahead and try to tweak the mill, but just remember that efficiency isn't the be all end all benchmark for brewing. YMMV, but on my system the difference between 65% and 75% breaks down to about a dollar worth of grain. Not dealing with a stuck sparge is worth a dollar to me. My concern is usually with consistency rather than efficiency. If I could nail 65 every time, I would roll with it rather than bouncing from anywhere between 65 and 85. Just food for thought I suppose.

I think you have to dial it on your own, ideal crush will be little different for different mash tuns. In my case i was getting 70% out of the box then i star playing with my corona, got stuck sparge, dial it back a little and got suck again, dial back some more and hit 75%, crank it a tick and last two brews i was at 82% and i was draining my tun very fast, im gona leave it as it is now

Tough question. I've been hitting 65% or so with my corona-style mill, but I can't tighten much more without burning out my drill motor (and getting mostly flour). I do stovetop BIAB, though, so it's a little more expected.

One thing, though: if you can get 65% consistently, don't be too bothered. I was ticked last batch that I only got to 65% instead of 70% like I'd hoped, but then I figured it's such a small difference to compensate for -- the negativity of missing my target was ruining a brewday, which should be fun, right? Anyway, I'm just going to start shooting for 65%, spending the extra fifty cents or a dollar on grain each batch, and not sweating it so much. Consistency is what I wanted with the mill anyway. Just my two cents.

I have my CM cranked down pretty tight. I get some flour in my crush. At the setting I run it, I can't use a drill, it's too tight and binds the drill, but turns very easily by hand.

I'm running in the 73% range +/- 1% per batch. I'm pretty sure I've gotten all I can from the mill, and need to look at my sparging technique to up it a few % points.

Give it a quarter twist and go from there. I agree though, an extra pound of grain beats a stuck sparge any day of the week. I get damn spot on 70% consistently and don't care about more or less with the quality of beer coming out.

 

[Beer_Eugenics]

So I gave it a 1/2 a turn and still got 65 which is what I was getting from milled grains from AHS. It only has 1 turn left before its to tight. Im going to give a 1/2 a turn more and be happy with that thanks.

I use feeler gadges. I use .34 or is it .034 I cant remeber , that seems to be prime for corna mills.
