comparison between open circuit and close circuit ball mill

  • Milling (machining)Wikipedia

    Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes cutter head speed and pressure. Milling covers a wide variety of different operations and machines on scales from small individual parts to large heavy-duty gang milling operations.
