Application: Lab sieve is widely used to determine cement fineness. Air flow takes the role as dynamic media. The whole system is under negative pressure,  specimen under test will be in flow state under the action of airflow sprayed by the rotating gas nozzel,  and travel along with airflow. Fine particles whose  size smaller than sieve aperture are extracted away, leaving particles whose size larger than sieve aperture.
