In the field of fine powder analysis and classification, even the smallest differences in particle size distribution can have a significant impact on material performance. The YK-QLS Airflow Sieve, developed by Yika (Shanghai) Technology Co., Ltd., is designed specifically for the classification of powders ranging from 15–5000 μm, helping laboratories and production environments achieve higher standards of quality control.

　　High-Accuracy Airflow Classification — Breaking Through Traditional Limitations

　　The YK-QLS utilizes an airflow jet principle, where stable, high-speed airflow disperses particles uniformly across the sieve surface. This enables precise classification up to 800 mesh.

　　Compared with traditional mechanical vibration sieves, the airflow process prevents agglomeration and sieve clogging, ensuring that powders remain fully suspended during separation.

　　• Wide particle size range (15–5000 μm)

　　• Ideal for finer, lighter, or more cohesive powders

　　• High repeatability with low measurement error

　　Smart Control—Ideal for Laboratories and Pilot-Scale Production

　　With intelligent programmable control, users can easily set the screening time, vacuum level, and rotation mode to ensure stable and efficient operation.

　　• Adjustable vacuum level: 0–10 kPa

　　• Continuous operation supported, with screening duration up to 9999 minutes

　　• Forward–reverse rotation reduces sieve load and extends service life

　　Clean, Safe, and User-Friendly Operation

　　The YK-QLS features a fully enclosed structure to prevent powder leakage, protecting both the laboratory environment and operator safety.

　　A transparent top cover and data-printing function allow each test to be fully traceable and well-documented.

　　Versatile for Multiple Industries

　　Capable of handling chemical raw materials, food powders, pharmaceutical intermediates, and metal powders, the YK-QLS is a key device for high-precision powder classification. Its adaptability and accuracy make it widely applicable in:

　　• Fine chemicals

　　• Pharmaceutical research

　　• Food additive screening

　　• Powder metallurgy and advanced material research

　　A Smarter, More Reliable Approach to Fine Powder Screening

　　The YK-QLS Airflow Sieve delivers stability, precision, and efficiency in a compact and intelligent design—providing a dependable solution for modern powder classification needs.
