  • Autogenous Grinding & Semi Autogenous Grinding Circuits

    The first question that we at Allis-Chalmers ask about the feasible application of primary autogenous or semi-autogenous grinding mills concerns the quantity and the competency to be media of media-sized ore in the feed. These are the first factors to be appraised, since if there is not enough media-sized ore and/or if the media-sized ore will not perform as media in an autogenous or semi

  • Autogenous and Semi-Autogenous Mills FLSmidth

    Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments

  • Autogenous and Semiautogenous Mills Datasheet -- liming

    AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many applications.

  • SAG Mill Variable Speed Drive

    A variable speed drive on large primary semi-autogenous mills can overcome this problem to a considerable degree. A major disadvantage of large semiautogenous mills has been the necessity to keep the mills fully loaded at all times to minimize ball and liner breakage. As ore hardness and grindability change, feed tonnage has to be modified to compensate. This can result in over-grinding
