2、Overview

Negative screening analyzer is a new powder fineness screening tester, it is to meet the GB1345-91 "Test method for fineness of cement," the new standard dry sieving method requires special equipment, is widely used to determine cement fineness and cement production control.

The instrument has the screening high speed, high accuracy, recovery and good performances, widely used in cement, cement products , professional research institutes and colleges of cement testing laboratory, in other industries powder fineness tests also obtain application.

3、Working principle

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.
