Summary
The centrifugal classifiers are used for obtaining finely dispersed powders of set fractional composition within coarseness range from 10 to 400 μm.
Description
The centrifugal classifiers are meant for splitting finely
dispersed powder-like products within the range of 0.01-0.1 mm. Material is
split due to centrifugal force fields and airflow influence on the material
particles. Coarseness of the split products is controlled either by changing
rotary speed or by varying intensity of the airflow.
