New standard negative pressure screening analyzer

To cooperateGB/T1345-2004The standard "Method for Testing the Fineness of Cement - Sieve Analysis Method" specifies square holes45umScreening and80umThe implementation of the cement fineness sieve analysis test method reduces the influence of human factors during the test process and improves the test accuracy. Our factory has jointly developed with the Cement and New Materials Research Institute of China Academy of Building Materials ScienceFYS - 150Environmentally friendly intelligent digital negative pressure screening analyzer'The product is manufactured by China Academy of Building Materials Science Supervised and inspected by the Institute of Cement and New Materials, this product has advanced structure, long service life, and strong environmental performance The advantages of fast screening speed, high accuracy, good reproducibility, and wide applicability are at a high level and currently meet the needs of the countryGB/T1345The instrument required by the new standard sieve analysis method for cement fineness inspection.

2、 Purpose:

FYS-150Environmentally friendly intelligent digital negative pressure screening analyzer，Widely used in cement fineness inspection and cement production control, powder fineness testing in other industries can also be used simultaneously. This instrument is required for cement quality inspection, cement plants, fly ash and other units across the country.

4、 Working principle

FYS-150Environmentally friendly intelligent digital negative pressure screening analyzerUsing airflow as the power medium for screening, during operation, The entire system maintains a negative pressure state, and the powder material to be tested in the sieve is sprayed by the airflow from the rotating jet nozzle It is in a flowing state and moves with the airflow. Fine particles with a particle size smaller than the sieve aperture are pulled away by the airflow through the sieve, while coarse particles with a particle size larger than the sieve aperture remain in the test sieve, thus achieving the purpose of screening. By using a small cyclone dust collector in the screening system, fine particles that can pass through the sieve can be collected from the airflow with a collection rate of up to95%The above reduces the frequency of cleaning dust with the vacuum cleaner.
