  • High Energy Ball Mills Instead of Planetary Ball Mills

    For materials which cannot be alloyed by fusion, mechanical alloying is carried out in ball mills which provide high energy input through impact and friction. Trials have shown that the alloying process in the Emax takes considerably less time than in, for example, a Planetary Ball Mill. Further advantages include a better transformation rate ...

  • What is a Ball Mill?

    A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals. By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.
