The airflow screening machine uses aerodynamic screening to prevent agglomeration; samples are well dispersed, making it suitable for screening analysis of low-density, easily agglomerating fine particles. It is used with analytical sieves of 10 microns and above, the nozzle speed is adjustable, and the average screening time is 2-3 minutes. The continuous airflow ensures reproducible screening results.
