effect of stirrer speed on product size vertical stirred mill

  • Stirred Mills Ultrafine Grinding ScienceDirect

    In low speed vertical stirred mills, gravity may be considered one of the components of forces acting to produce the abrasive stresses. This has less of an effect in tower mills compared with pin stirred mills due to the lifting effect of the screw flights in the tower mill.

  • Predicting the product particle size distribution from a

    Agitator speed, grinding media size, and feed size were varied in the vertical stirred mill to evaluate their effect on the breakage parameters. Each grinding parameter was individually analyzed, while the others were held constant. Therefore, for each single-size fraction of feed, a total of twelve tests were conducted. After each test, the product was unloaded from the vertical mill

    External classification is not needed for the mill product because the mill speed can be adjusted to control the product size. The product particle size distribution is narrow due to the vertical mill design coupled with the internal classification effect of the discs.

  • Stirred Milling VERTIMILL® Grinding Mills & Stirred Media

    Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding

  • A Comparative Study on a Vertical Stirred Mill Agitator

    The 80% passing target product size of 38 μm was obtained with double helical screw agitator in 20 min of grinding with an expend of 10.53 kWh/t specific energy, whereas, the target product size of 38 μm was achieved with the pin type stirrer at the rate of 21.73 kWh/t. It is evident that grinding in a vertical stirred mill with a double

    Stirred media mills have proved to be more energy-efficient than the conventional ball milling for fine grinding applications. The mill performance is governed by a number of operating variables including mill stirrer speed, feed particle size, solids content and slurry rheology.

    2001-03-01· Abstract. The comminution of limestone and fused corundum in stirred media mills has been investigated regarding specific energy requirement. The experimental results show that the tip speed of stirrer discs as well as the density and the size of grinding media affect the specific energy required to achieve a certain product fineness.
