The NEA DCX fine classifier is a highly efficient air separator which, in particular, has its strengths in the classification of finest products. The fine classifier can be excellently directly integrated into existing grinding, classification and separating processes. The product to be classified is fed to this classifier in the process air. As a consequence, the product no longer needs to be separated again prior to classification.
The NEA ICX enables energy-efficient grinding in areas of fineness hitherto reserved for jet mills and ball mills. This now enables the realization of finest grinding in a compact, energy-saving grinding system, which does not require any additional aggregates such as air compressors.
