improvement of secondary grinding by stirred mills

  • Stirred mills for wet grinding SKD

    Stirred mills are used for wet grinding. Ideal for grinding finer products, stirred mills are known for operational efficiency and smaller required floor space. SKD offers both gravity-induced and fluidized technologies in Vertimill® and Stirred Media Detritors (SMD), allowing for the optimum equipment solution for your circuit.

  • Grinding Mills an overview ScienceDirect Topics

    According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills. In tumbling mills, the mill shell is rotated and motion is imparted to the charge via the mill shell. The grinding medium may be steel rods, balls, or rock itself.

  • Stirred Mills Ultrafine Grinding ScienceDirect

    Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

  • Stirred Media Detritors (SMD) SKD

    Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding. Lower capital cost.
