The ball mills are one of the extensively used super-fine grinding machines in industrial production. Ball milling can be divided into two types: dry grinding and wet grinding, both of which are suitable for grinding of various ores and other materials. Besides, the ball mills include the grate ball mills and the overflow ball mils according to the different ore discharge modes.

    In recent years, under the goal of energy conservation and consumption reduction, the ball mills have gained considerable development in terms of the drive mode, the liner, the materials of grinding media and the structure. Now the ball mills have the characteristics of large scale, high efficiency and energy conservation.
