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.

The mill heights can be varied to optimize the media load and power input for specific applications. Chamber volumes range from 5 to 30,000 liters with corresponding drives from 5 to 5000 kW. The HIGmill is the only ultrafine grinding technology in commercial use that can use small-size high-density grinding media in mill sizes above 3000 kW.
