Air classifiers are used predominately on fine powders but can be used on coarse particles up to 1000 microns in diameter. Air classifiers employ various airflow techniques including elutriation, free vortex, and forced vortex, either separately or in combination, to achieve the desired classification. Elutriation is a gravity-based particle ...Web

Furthermore, with active pulsed air classifiers, the pulse frequency was found to have little effect on the efficiency in the 1 to 2.5 Hz range, while symmetric and quick-rise pulse shapes appeared to outperform slow-rise pulse shapes. Active pulsed air classifier performance improved as the percentage of the air flow pulsed increased.Web

Abstract. Volute profile plays an important role in guiding the airflow for a turbo air classifier. The traditional volute design is based on the method of analogue and there is a lack of uniform theoretical design basis and guidance. To meet the needs of guiding the airflow better, a logarithmic spiral volute design method is put forward …Web
