The method of sorting impurities by the difference of the suspension speed of corn and impurities and using the effect of air flow is called air separation. Air mills are often used in powder mills to remove light impurities in raw materials.

According to the direction in which the airflow takes impurities away from the material, the air separation can be divided into vertical, horizontal or inclined air separation. Because the vertical air separation effect is more stable and anti-interference ability, it is most used in the powder mill.

According to the different installation positions of the air separation equipment in the wind network, the air separation can be divided into suction air separation and blowing air separation. The suction type air separation equipment works in a negative pressure state, the dust does not overflow, and the working effect is relatively stable, so this form is generally adopted.
