Planetary mills
Planetary ball mills are characterised by very fast and effective comminution. They have a wide range of applications. Ideal for lossless comminution down to extremely high levels of fineness < 0.1 µm. The grinding can take place dry, in suspension or under inert gas, depending on the application. They are also well suited for mixing and homogenising emulsions and pastes or for mechanical alloying in materials research.
A comparison with our classic line Planetary mills
As an extension to the existing classic line of planetary mills, FRITSCH now offers for the first time a premium line generation. Previously unachieved rotation speeds are now possible, yielding ultra-fine grinding results down to the nano range. FASTER, SIMPLER AND SAFER THAN EVER.
