Mikro Air Jet Sieve® MAJSx Pre-owned

Made In The USA
The Mikro Air Jet Sieve® MAJSx is a highly accurate and reliable particle size analyzer which identifies the particle size distribution of dry powder ranging from 20 µm / # 635 (mesh) to 4,750 µm / # 4 (mesh). The versatile and economical analyzer is used by hundreds of laboratories throughout the world in the chemical, mineral, pharmaceutical, food, plastic, and cosmetic markets. It is more economical than a laser diffraction analyzer and more accurate than oscillating or stacked sieving devices. Move over, the Mikro Air Jet Sieve® is easy to operate and maintain.
   

Key features

  • Pneumatic sieving, dispersion of the sample while continuously cleaning test sieve.
  • Simple analysis data saving to the on-board computer.
  • Sample Volume 10 to 100 grams/cycle analysis.
  • Output graphs in Linear-Linear or Rosin-Rammler Distribution formats.
  • Capable of calculating particle size points at 0.01 to 99.99% using the Rosin-Rammler Distribution format.
  • Available in Basic Manual Computer Software Guided mode with the option to convert to Advance mode.

Target Applications:  While most customers use the air jet sieve to determine the particle size of dry powder ranging from as fine as 20 µm / #635 (mesh) up to 4,750 µm / #4 (mesh), some utilize the particle size analyzer to determine the average particle size below a specified cut point; such as D90 < 50 µm.  Others use the air jet sieve to confirm that a powder top size does not exceed product specifications. The Mikro Air Jet Sieve® MAJSx can even be used as a small lab-scale classifier to remove the fine particles out of a sample or as a dedusting system to remove undesirable dust from small batches.

How it Works:  The Mikro Air Jet Sieve® MAJSx utilizes test sieve screens and the pneumatic sieving principle to enhance the accuracy and reproducibility of particle size analysis. This method has become the preferred standard for such tasks as quality assurance of incoming raw materials, process control, and verification of final product specifications. While under negative pressure, a positive upward air flow is emitted from the rotating slit wand which continuously disperses particles across the surface of a test sieve screen. Those particles that are smaller then the opening of the test sieve screen pass through and are carried away from the sample, leaving the particles larger than the sieve opening on top of the test sieve screen. Particle size within the range of 20 to 4,750 µm can quickly be determined. The unique rotating slit wand feature also reduces, and in many cases, eliminates the need for tapping or brushing, thus enhancing the analysis reproducibility. The overall system is designed for cleaner operation and requires less counter space than other types of analytical equipment.

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 damage such as holes, tears, scratches, waves, or other imperfections are not recommended. Sieve screens should be routinely re-certified to insure accurate analysis results.

Performance at an Economical Cost: Certified pre-owned Hosokawa Air Jet Sieves analyzers start at $4,400. Prices can vary dependent on the number of sieve screens required, vacuum selection, balance type, optional components, taxes, and shipping.
