Type B cement negative pressure sieve analyzer negative pressure sieve wholesale price
Precautions for using the cement negative pressure sieve analyzer:
●Dump the cement in the dust collection bottle regularly.
●If the negative pressure does not meet the national standard requirements (~) after being used for a period of time, please clean the dust bag in the vacuum cleaner.
●The vacuum cleaner should not work continuously for more than 10 minutes, otherwise it will easily overheat and burn out.
Operating procedures for cement negative pressure sieve analyzer:
●Place the test sieve on the sieve analyzer to check the sealing performance.
●Weigh the sample according to the required number, pour it into the test sieve, and close the sieve cover.
●Plug into the power socket (note: the power socket must be grounded).
●Turn on the switch according to the required screening time, and the screen analyzer starts to work.
●After automatic shutdown, weigh the sieves in the test sieve to obtain the sieving measurement results.
●After each use, the case should be cleaned promptly and wiped with a soft cloth moistened with soapy water. Do not wipe with gasoline.
●When the screen is clogged, you can place the screen upside down on the screen analyzer, cover the screen cover, and perform back-suction for a period of time.
Cement negative pressure sieve analyzer test results:
Calculate the sieve residue percentage of the cement sample according to the formula:
Where: the sieve residue percentage of the cement sample (%)
Cement The mass of the sieve residue ()
The mass of the cement sample ()
The calculation result is accurate to .%
Cement negative pressure sieve analyzer:
It is a novel powder fine The fineness sieving tester is a special instrument that meets the requirements of the dry sieving method of the new standard B "Cement Fineness Inspection Method" and is used for cement fineness inspection and cement production control. This instrument has the advantages of fast screening speed, high precision and good reproducibility. It is widely used in cement quality inspection stations, cement production plants, scientific research institutes and cement physical property testing laboratories of universities and colleges. It is also used in powder fineness testing in other industries. It has also been applied in China.

Working principle of cement negative pressure screen analyzer:
When the cement fineness negative pressure screen analyzer uses airflow as the power medium for screening, the entire system maintains a negative pressure state, and the precision to be measured in the screen is The powder material is in a fluid state under the action of the air flow ejected from the rotating air nozzle, and moves with the air flow. The fine particles whose particle size is smaller than the screen aperture are driven by the air flow through the screen and are pumped away, while the particle size is larger than the screen mesh. The coarse particles in the holes are left in the screen to achieve the purpose of screening. If a small cyclone dust collector is used in conjunction with the screening system, the fine particles passing through the screen can be collected from the air flow, and the collection rate can reach more than ℅, thus reducing the number of vacuum cleaner cleaning times.
