In contrast to conventional Planetary Mills, the rotational speed of the grinding bowls and supporting disk can be configured separately in the Vario-Planetary Mill PULVERISETTE 4 classic line with 2 working stations.
Your advantage: A single mill for mechanical activating and alloying providing optimum grinding conditions suited to the respective material to be ground and the size of the grinding bowls and balls! For results that cannot be achieved with other Ball Mills.
Your advantage due to the Variable Transmission Ratio
The PULVERISETTE 4 classic line also operates according to the Planetary Principle, but the transmission ratio between grinding bowls and supporting disk is variable adjustable. Your advantage: You can directly influence the movement and paths of the grinding balls: Depending on the setting, you can obtain high impact energy or high friction, according to your needs, or have your PULVERISETTE 4 classic line operate as a Centrifugal Mill. You are free to choose all intermediate levels and combinations between friction-based and impact-based comminution.
This makes the mill uniquely versatile.

FRITSCH Plus: Measurement of gas pressure and temperature
The Vario-Planetary Mill PULVERISETTE 4 classic line can be combined with the GTM-System for measuring of the gas pressure and temperature during grinding. This turns your mill into an analytical measuring system.
