  • Stamp millWikipedia

    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 OPTIMAL BALL DIAMETER IN A MILL

    and with the decreased grain size the necessary ball size also decreases (Olejnik 2010 2011). For each grain size there is an optimal ball size (Trumic et. al. 2007). The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding. In both

  • Calculate Ball Mill Grinding Capacity

    The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
