Breaking the Boundaries of Sample Sieving – YK-QLS Air Jet Sieve, Offering a New Choice for Your Powder Analysis

The air jet sieve equipment can meet the basic needs for air jet sieving of certain powders. Place the powder sample to be tested into the instrument, then activate the negative pressure generation device and the timer on the touch screen to perform air jet sieving on the powder. The air jet sieve realizes the air jet sieving theory of classification first and sieving later, and can also determine the percentage of particle size limits.

It can meet the basic needs for air jet sieving of certain powders. Place the powder sample to be tested into the instrument, then activate the negative pressure generation device and the timer on the touch screen to perform air jet sieving on the powder.

The instrument internally uses an imported electronic vortex generator from the United States. With the cooperation of the negative pressure generation device, the air jet sieve produces a precise and sensitive negative pressure air vortex. This vortex drives the powder to rise through the nozzle, collide with the sieve lid, and remove agglomerated particles. The powder is re-sucked by the vortex onto the standard test sieve in order of size. Smaller particles pass through the sieve mesh and are stored in the negative pressure generator or sample collector, while larger particles remain on the test sieve. Throughout the process, the electronic vortex generator controls the three-dimensional movement of powder particles by size, realizing the air jet sieving theory: classification first and sieving later. By replacing test sieves with different mesh sizes for sequential sieving, the percentage of particle size limits is ultimately obtained.

In the field of powder analysis and sieving, accurate classification and sieving processes of sample particles are crucial steps to ensure reliable analytical data. To meet the needs of research institutions, testing laboratories, and production applications for particle sieving, Yika (Shanghai) Technology Co., Ltd. has introduced the YK-QLS air jet sieve, suitable for particle sieving in the range of 15 micrometers to 5000 micrometers. Analysis and sieving cover ceramic sand, metal powder, mineral powder, chemical powder, etc.

It is particularly suitable for sieving fine particles, removing agglomerated particles, and obtaining the percentage of particle size limits.

It provides process support for research, quality testing, raw material development, and other stages.
