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 industrial minerals and pigments.
