  • Stamp mill

    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 repeated at the next pass of the cam.
