    Vertical windmills. The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century first used in northwestern Europe in the triangle of northern France eastern England and Flanders. It is unclear whether the vertical windmill was influenced by the introduction of the horizontal windmill to Southern Europe in the

  • VXPmill for fine ultra fine grinding FL

    The mills are designed to run at tip speeds between 10 and 15 m/s and are capable of operating with very dense grinding media. The result is a power intensity that is higher than the low-speed mills and overlaps that of the high-speed mills. There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the

  • Wet grinding of CaCO3 with a stirred media mill Influence

    Stirred media mills also referred to as stirred ball or stirred bead mills generally have a good ability to produce fine particles with a relatively narrow particle size distribution. Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 μm such as
