STUDYING OF NEWF CENTRIFUGAL-ROTOR SUPERFINE-POWDER AIR-CLASSIFIER

The new type of NEWF-4A centrifugal-rotor superfine-powder air-classifier was developed,by which many materials can be classified to obtain micron or submicron powders. A mathematical modelhas been established which indicates the relations between theoretical cut size and average size of classifiedfine product. The developed mathematical model is very useful to calculate the variables of classification forthe air classifier.
