New NETZSCH-Mill for the use of ultrafine grinding media

For the comminution down to the nanometer size range or for the dispersion of nano-sized particles the use of finer and finer grinding media is necessary. Furthermore for the avoidance of changes in the crystal structure of the product smooth conditions for dispersion processes are very important. With the new mill developed by NETZSCH-Feinmahltechnik GmbH a very good separation of grinding media with diameters down to 50 mu m is possible even for low stirrer tip speeds. The poster shows the principle design and first results obtained from experiments with the new mill.
