OK, so I've been researching DIY mills. My beer allowance is not that large and cannot spend a great deal on equipment - besides, I can build some fairly decent equipment.
Back to DIY mills. I've read enough to guess is a bit of debate regarding concrete rollers. On one side we have the contamination argument about getting concrete in your beer. On the other side, there is the camp that says if your rollers are not hitting anything, they should not be getting damage and concrete in your crushed grains. The argument being we are crushing grain, not grinding flour - so the rollers should not hit anything. Grain is much softer than concrete so it will give.
Even if you did get some concrete contamination, won't the grain bed filter this out?
What are your thoughts? Any other thoughts to alternate diy rollers?
