Nanoparticle Production with Stirred‐Media Mills ...

Nanoparticles can be produced by wet grinding in stirred‐media mills. In the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even after stressing events with high stress energies.

THE EFFECT OF GRINDING MEDIA PERFORMANCE ON

2019-1-6  Abstract. This study aimed to conduct systematic research on the design of high-density zircon (ZrO 2) grinding media (0.2-1 mm) in a laboratory-scale media mill (750 ml) for wet grinding of calcite (CaCO 3, d 50 = 5.4 µm). Sub-micron grinding experiments were carried out by using different amounts of finer grinding media (25%, 50% and 75%) and different size ratio of finer-coarser media
