Target Applications:  The Mikro Air Jet Sieve® model MAJSx2 is a highly versatile particle size analyzer used by hundreds of laboratories around the world testing thousands of materials. Most customers use the Mikro Air Jet Sieve® model MAJSx2to determine the particle size of dry powder ranging from as fine as 20 µ m / #635 (mesh) up to 4,750 µ m / #4 (mesh). Some customer use it to determine the average particle size below a specified cut point; for example, D90 < 50 µ m while other customers use it to confirm a powder top size does not exceed product specifications. The Mikro Air Jet Sieve® model MAJSx2 can even be used as a small lab scale classifier to cut the fine portion out of a sample or used as a dedusting system to remove undesirable fine dust from small batches of product. How it Works:  The Mikro Air Jet Sieve® model MAJSx2 is easy to operate to quickly determine the particle size of a powdered sample with a short series of test sieve screens. The system utilizes the pneumatic sieving principle that enhances the accuracy and reproducibility of particle size analysis. Use of this device has become a preferred method for such tasks as quality assurance of incoming raw materials, process control, and the confirmation of final product specifications. While negative pressure draws all the particles below a defined particle size down through a test sieve screen, a positive airflow is introduced upwards through a rotating wand. This airflow deagglomerates and disperses undersized particles and carries them to the vacuum collector.  Key Operating Parameters Enhance Repeatability & Reliability:  The sieving time plays a major role in determining particle size with an Air Jet Sieve. Excessive sieving time can lead to particle degradation due to attrition. In most dry powder applications, Hosokawa recommends a two-minute sieving time cycle which provides ample time for the particles of the entire sample to pass through the sieve screen or be retained. Sieving vacuum pressure between 8-16 inches of water column is recommended during a sieve analysis. If the pressure is too low, the air velocity passing through the rotating wand may not be sufficient to evenly disperse the entire sample. If the pressure is too high, the air velocity could generate enough force to further grind material as the sample repeatedly impacts the sieve screen and sieve cover. A sample volume between 10 and 100 grams is recommended in most air jet sieve particle analyzers, depending on the density of the material being tested. Samples larger than 100 grams have the potential to blind the test sieve screen and affect the analysis results. Test sieve screen quality and integrity is critical in any particle size analysis process. Hosokawa provides test sieve screens that are 99% accurate. Test sieve screens with any damage such as holes, tears, scratches, waves, or other imperfections are not recommended. Test sieve screens should be routinely recertified. Performance at an Economical Cost Hosokawa’s Air Jet Sieves start around $4,400 for certified pre-owned analyzers and goes up to $16,000 for the most advanced system with required ancillaries and optional cyclone. Prices for Air Jet Sieves differ depending on the number of sieve screens required, vacuum selected, balance type, optional components, taxes and shipping costs.

Basic Operation Mode:

In the basic mode, the Mikro Air Jet Sieve® model MAJSx2
allows
operators to utilize the basic functions of the particle size analyzer to
screen materials and manually determine the amount of material retained and
passed. This version is most suitable for applications where operators only
need to quickly evaluate the particle size at a specific micron size.

Advance Operation Mode:

The advanced mode utilized the built in touch screen
computer to collect and calculate particle sizes from a number of test sieve
screens, generating a distribution. Additionally the operator can connect the Mikro Air Jet Sieve® model
MAJSx2 to a compatible balance and printer. This version is
the most versatile and,
as a result of the menu guided software, the easiest operate.
