Water Mill Demonstration at Otterton Mill 

Facts

It surprises me just how long mill technology has been around. In the ancient Roman era there were turners, and what today we call lathes. Meanwhile 90% of the world was still hitting things with rocks.

I feel like a couple grams of bugs ground in with several tons of flour is probably pretty insignificant in the grand scheme of things :P

Bugs are also full of protein so it will not harm you if a little is in your flour.

WessCNY this is a loo late but I don’t think they change them unless the stone splits in half as a stone does not get dull.

it depends on how much grinding they do, what kind of stone was used, and what they are grinding. A video on George Washington's grist mill says about once a month in that case, but not replaced, the stones get 'dressed' with a chisel to restore the grinding face and sharpen the surface. I think generally not as often as once a month, but I am just speculating. Here's the Mt. Vernon video with the stone dresser: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-othUyF4f3Ww.html Oh, I see you posted 9 years ago. Not sure if my answer will reach you lol

If there was a drought there would be no wheat to grind. A lot of mills had a large mill pond upstream which stored water for when it was needed
