In Planetary Ball Mills, the comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls.


PULVERISETTE 4 classic line: Thanks to free selection of the grinding parameters, the PULVERISETTE 4 classic line is the ideal Planetary Mill for mechanical activation and alloying. The main areas of application lie in materials research and naturally anywhere that an effective, innovative Laboratory Planetary Mill is required.

Areas of application
The Vario-Planetary Mill is capable of simulating ball mills of typical design, precisely recreating the load types found in such mills and thereby reproducing or optimising the grinding processes.

Method of operation
In contrast to typical Planetary Mills, the innovative Vario-Planetary Mill allows for configuration of the speeds for grinding bowls and the support disc completely independently of each other. This makes it possible for the first time to perform both mechanical activation as well as mechanical alloying with a single mill through modification of the gear ratio.

Features overview
  • Free programming of the grinding parameters, incl. grinding and pause times and grinding cycles through PC software
  • Real-time display of the rotational speed for monitoring of the grinding process
  • WINDOWSTM control and evaluation programme
  • Reversing function
  • Forced air ventilation of the grinding chamber
  • Safety interlock of the grinding chamber with standstill monitoring
  • Overload protection through rotational speed adjustment
  • Maintenance-free drive
  • Fault free long service life due to high-performance belt drives and permanently lubricated bearings
  • Robust steel housing, service-friendly design
  • Membrane keyboard
  • Certified safety CE
  • 2-year guarantee

Equipment

The standard equipment delivered with the Vario-Planetary Mill PULVERISETTE 4 classic line includes 2 bowl mounts and clamping; however, it includes no grinding bowls or balls, which are available in 8 different materials and must be ordered as accessories.

Suitable for the following material samples
hard, medium-hard, soft, brittle, tough, moist


Please note: For this FRITSCH mill, you require at least two 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, larger or heavier grinding bowls and grinding balls with a higher density can be used. Please take note of the useful capacity, this is not identical with the bowl volume!
