Airflow conveying sifter is also called pneumatic inline sifter, airflow conveying vibration screen. It is used for screening dry materials transported by airflow. And it can also be used to separate smaller particles from larger particles, and to remove foreign matter. This sifter screens dry material only while being pneumatically conveyed.
The upper and lower frames are connected by a by-pass tube, which is used to balance the upper and lower pressure of the screen so as to avoid too short screen life.
It is mainly used in flour, starch, salt, sugar, plastics etc.
