It 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.
Fineness range: 0.030~1.000mm
Sieve time range: 0-599sec
Negative pressure: 4000-6000 Pa
Noise: less than 75db
