    Influence of slurry rheology on stirred media milling of ...

    Oct 19, 2007  Chemicals have an important effect on wet ultra-fine grinding in stirred media mills since the addition of chemicals can modify the slurry rheology of ground slurry (He et al., 2006a). The effect of the addition of Flotigam P or Dispersant S40 on the ultra-fine grinding of quartzite was investigated.

    VXPmill for fine ultra fine grinding FLSmidth

    There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
