Nano mill Zeta® RS

Innovation in Wet Grinding Technology


The nano mill Zeta® RS is the next development of the worldwide known circulation mill system Zeta® type LMZ. Its field of application starts where the other agitator bead mill system Zeta® ends. The highly efficient centrifugal separation system enables the use of smallest grinding media from a diameter of 30 – 300 µm in reliable continuous operation. It is specially designed for wet grinding and dispersing processes especially “gentle dispersing” in the nanometer range. Working with the machines is a pleasure due to its easy operation.

The agitator bead mill Zeta® RS is equipped with a swiveling grinding unit and lifting device with multiple positions for easy emptying, filling and cleaning and a horizontal working position.
