About one ton of ore would be pulverized by each stamp every 24 hour day.

While the cam moves from under the stamp, the stamp falls on the underlying mineral, crushing the rock, and the lifting process is repeated at the next step of the cam. Each frame and stamp is sometimes called "battery" or, confusedly, a "stamp" and mills are sometimes categorized by how many stamps have, that is, a "10 mill of stamps" has 10 sets.
