The next Generation of Agitator Bead Mills

NETZSCH-Feinmahltechnik GmbH has now developed the new Alpha® modular machine platform. Compared to earlier-generation machines, this series is designed such that different grinding systems can be mounted on the same base platform as appropriate for a defined drive capacity.

Circulation mill system Type Zeta®

The circulation grinding system for all fields of application. Suitability for all viscosities and nearly all products is achieved with different grinding media from 90 µm to 3 mm. This provides highest product qualities and fineness down to the nanometer range.
