  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.

  How it Works: Crushers, Grinding Mills and Pulverizers

  Rock crusher. Material is reduced by crushers and grinders by fracturing, which takes place when the material is put under stress by the moving parts of the crushing or grinding equipment. Forces applied during the process may be compressive, shear or impact. The material fractures when the internal strain levels reach a critical level.
