In powder R&D and quality control, the real challenge has never been “ordinary samples,” but rather those subtle yet critical powder characteristics that easily compromise results:ultra-fine particle size, low bulk density, strong tendency to agglomerate, and electrostatic charge.
Conventional vibratory sieves often lead to screen blinding, particle breakage, and inaccurate data under these conditions.
This is precisely why Yika (Shanghai) Technology developed the YK-QLS Air Jet Sieve:
to let sieving reflect the true nature of the material—without interference from the equipment itself.
Sieving with air, not vibration—for truly representative classification
The YK-QLS employs a stable, precisely controlled airflow as its sieving force. Operating under negative pressure, it fully disperses powders, allowing them to pass naturally through the sieve mesh for accurate size separation.
This gentle, non-destructive process delivers more authentic results that better represent how powders behave in real-world applications.
It excels particularly with:
• Ultra-fine powders and low-density materials
• Powders prone to agglomeration or static charge
• Samples requiring high repeatability in particle size analysis
Designed for laboratory efficiency
From sample loading and sieve mesh replacement to cleaning and maintenance, every detail of the YK-QLS is engineered for efficient experimentation.
It requires only a small sample amount per test, features intuitive operation, and delivers consistent results—making it ideal for both detailed R&D analysis and routine quality control in production.
More than just an instrument—a smarter sieving philosophy
At Yika (Shanghai) Technology, we believe reliable sieving results come from the synergy of equipment and methodology.
Based on your specific powder characteristics, we assist in selecting the optimal sieve mesh and testing protocol—ensuring every sieving run delivers meaningful, actionable data.
As powders become increasingly “refined,” your sieving approach must become smarter too.
