    Stirred media mills are used for particle size reduction of calcite (calcium carbonate); they consist of a grinding chamber, ceramic beads (media), and impellers. The specific energy input during the milling process is proportional to the reduction in size of the particles [1]. Milling is a high energy process but product quality and energy requirements can be improved through

    Analysis of energy requirements in stirred media mills

    Vertically stirred media mills represent an important tool for the comminution of a range of industrial minerals. In this work, calcium carbonate is ground to size ranges below 2 μm in an Imerys stirred media mill. The role of grinding media on the efficiency is considered, and with the use of a novel, rod shaped grinding media, significant energy savings in ultrafine wet grinding are seen.

    A gas fluidizedbed stirred media mill is provided for comminuting solid ticles. The mill includes a housing enclosing a porous fluidizing gas diffuser plate, a baffled rotor and stator, a hollow drive shaft with lateral vents, and baffled gas exhaust exit ports. In operation, fluidizing gas is forced through the mill, fluidizing the raw material and milling media.

    Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful appliion of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning a number of industries that require fine and ultrafine grinding. In the context of ...

    Stirred media mill decreased bauxite d 50 size from 780 to 5 µm in 3 min. But, the ball mill has reduced to 455 µm at the end of the same grinding period. In addition, the energy consumed by the ball mill for similar fineness (5 µm) was approximately 300 kWh/t energy, whereas the stirred media mill consumes approximately 174 kWh/t energy. As a result, the stirred mill consumed less energy ...
