Hence, a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any freegold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground.

Richards gives the average amount of water used in 21 mills as gallons per stamp per minute, or tons of water per ton of ore crushed. The average duty of a miner's inch in a gold stampmill is given by P. M. Randall as 12 tons of quartz if the head under which the water is supplied is 4 inches, and tons if the head is 7 inches.

A stamp mill consists of a set of heavy steel ( iron shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is ...

A hammer mill drags hammers, you just have a mill. Or, your hammers aren't visible. But, for the purpose of silver oxide batteries, it does the job, as I believe all it has to do is open the case. If you want to use it to pulverize IC's or something along those lines, it will work much better with hammers and a screen.
