  • High Energy Ball Milling – Union Process

    The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while Attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process.

    The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.

  • BASIC CEMENT PLANT LAYOUT

     · Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.
