Toll Grinding
Screening / Classifying
A customized solution, even for the trickiest separation tasks: NETZSCH offers a broad range of systems and technologies for separation. Our screening machines are used primarily for separating oversize particles from special-effect pigments. The dynamic air classifiers master extreme demands – such as abrasive or high-purity products – with the highest degree of separation.
