We have a flour mill for grinding grains. The one thing you have to be careful of is to make sure that there are no stones in whatever you are grinding.
They’ll ruin a mill in a heartbeat.

In 1926, my friend Mary and her husband Jay owned the Yuma, Az flour mill.
They Yuman Indians would bring their corn for Jay to grind, and to get a bigger return, would put large rocks in the bags.
Mary says that Jay very carefully gave them back and thanked them for the gift.
In the future, they did not bother adding the stones.
