Im not disagreeing with you I was simply stating actual work hardened or cold rolled is a form of hardening. Anyone who has accidentally work hardened the side of their brewing kettle while drilling the hole in the side can tell you that.Hey, I’m not bashing the mill, I’m happy with my purchase.
Im just stating, none of the official documentation states the rollers are heat treated or hardened, and my empirical evidence supports that.
We don’t need to get into a pissing match on metallurgy, but these are not heat treated rollers. A single pass with a file digs right in, hardly different than my barley crusher rollers. Cold rolling or working mild steel will increase its hardness, but it’s not the same as a higher carbon steel or tool steel that’s been heat treated.
With that said, the knurling is much more aggressive, and the 1.5” diameter rollers should improve the angle the grain pulls into the mill. This is a much better mill than the BC, and the steel hardness doesn’t concern me. Hardened rollers are likely overkill for a 1.5” 3roller mill in the home brew setting.
I just wanted to clear up the info for anyone trying to compare apples to apples pricing with a similar mill. I would not compare these to other ‘heat treated rollers’. But this mill is less than half the price of a 3 roller heat treated mill, so it sorta makes sense.
The amount of grain you’ve put through yours is impressive. That’s 500 batches at my scale, which would be like 20-30 years of brewing, so that’s fantastic news.
What do you have your gap set at?
They do advertise cold rolled steel I think that and hardened cold rolled steel is all Ive seen some resellers advertise. The thing is the barley crusher advertises "1018" cold rolled steel rollers too and these are definitely harder than what they are using.
Are there any home brewing mills that you know of that state they have high carbon or tool steel rollers? I know MM stated theirs are cold rolled as well.
I actually have one, unfortunately despite the rollers being black carbon steel, the mill was very very poorly made so poorly made I demanded my money back and the seller didnt even want to pay for return shipping.
