The PULVERISETTE 7 classic line with 2 working stations is ideally suited for fast, uniform, and extremely fine comminution of very small samples down to colloidal fineness of hard, medium-hard, brittle and moist samples. Depending on the desired final fineness can the grinding be performed dry or in suspension. Besides for comminution, the Planetary Ball Mill can be utilized for mixing and homogenizing of emulsions and pastes. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls.
For the Planetary Micro Mill PULVERISETTE 7 classic line, you require at least 2 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!
