A Complete Guide to Purchasing an Air Classifier

Air Classifiers can separate fine particles that are in the range of 175 microns. However, size distributions typically fall somewhere in the 5–70-micron range. Is your material combustible? If you plan to work with a combustible powder, you need to ensure that your air classifier has the necessary suppression systems in place.

Evaluation of the performance of the cross-flow air classifier …

To overcome this shortcomings the application of the cross-flow air classifier is proposed. The air classifier is applicable to the manufactured sand processing if the PSD of any of the material collected in F1 to F3 is within the standard limits depicted in Fig. 2. The classification process may also be evaluated by means of two cut sizes.
