  • Grinding balls, buy metal balls from Metinvest manufacturer

    A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.

  • 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.
