A new planetary ball mill PULVERISETTE 7 premium line, from FRITSCH GmbH, has been launched recently. The company provides customers with the ability to comminute small samples up into the nano range (1 nm = 10-9 m) with this comminution concept. An example is new medications with nanoscale-active ingredients, which are of particular interest to the pharmaceutical sector. The human body absorbs active ingredients in the nano scale a lot faster than conventional compounds, reducing the dosage of medications due to better bioavailability. As well as achieving the same therapeutic effects with less active ingredients, unnecessary side effects can also be reduced. The enlarged specific surface of nano particles which effectively illustrate new catalytic attributes is also why there is a demand for nano particles in the chemical sector. In a planetary mill, the sample is placed together with the grinding balls into a grinding bowl. The grinding bowls are fastened onto the sun dial and counter-rotate around the center of the disc. The sample is successfully comminuted through beating, crushing, and grinding processes. For conventional planetary mills, the maximum possible speed range ...
