Instrument Introduction The German Sieber SLS 200 airflow sieve instrument is designed for the rapid and accurate screening of fine powder (2um ~ 4000um) in modern laboratories. Due to the fact that fine powders with a particle size of less than 4000um are susceptible to agglomeration, static electricity, and clogging of the sieve pores of the analysis sieve during the screening process, traditional vibratory screening instruments have been unable to accurately and quickly screen such fine powders. . These fine powders include paint, cement, fly ash powder, flour, chemicals, fine powder of Chinese and Western medicine, graphite powder, metal powder, clay powder, starch, light and heavy calcium powder, fine glass fiber powder and other materials.

The SLS200 airflow sieving instrument samples the specially designed rotating air-jet tank and the destaticizing device to perfectly meet the fast and accurate screening results. It is widely used in the screening and grading of powder materials in the chemical, paper, metallurgy, building materials, medicine, food, rubber, plastic, machinery, mining and other industries.



Instrument principle:

The air flow from the rotary air-jet tank located under the screen continuously unclogs the mesh and continuously throws up the fine powder to disperse it back to the surface of the screen, and the negative pressure and material Under the action of gravity, the fine powder smaller than the particle size of the screen quickly passes through the screen to achieve fast and accurate screening results. SKS 200 meets international and domestic quality control standards for coatings, cement, construction, coal, and pharmaceutical industries.
