  • Stirred mills - for wet grinding - Outotec

    Ideal for grinding finer products, stirred mills are known for their energy efficiency and compact design, reducing floor space requirements. These mills are based on gravity-induced and fluidized technologies, allowing for the optimum equipment solution for all comminution circuits covering secondary, tertiary, fine, ultrafine, regrind, and lime slaking applications.

  • Stirred Mills – Ultrafine Grinding - ScienceDirect

    2016-1-1 · 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
