Product Description

Cement Negative Pressure Sieve Analyzer

Cement Negative Pressure Sieve Analyzeris 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.

The negative pressure screen analyzer is a new kind of powder fineness screen tester, it is a special instrument which meets the requirements of the new standard dry screen method of gb1345-91 cement fineness test method, and it is used for cement fineness test and cement production control.This instrument has the advantages of fast screening speed, high precision and good reperformance, and is widely used in cement quality inspection station, cement production factory, scientific research institute and cement physical performance testing laboratory of colleges and universities.

一、Uses

FYS150 Negative Pressure Sieve Analyzer is a special instrument for sieve analysis in accordance with the national standard GB1345-91 "Cement Fineness Inspection Method 80μm Sieve Analysis Method". It has a simple structure, intelligent processing and convenient operation, high precision and good repeatability. Features such as reduced energy consumption. It is an indispensable instrument for cement plants, construction companies, scientific research institutes and universities and colleges with cement majors.
