Attributes Of The Mikro Air Jet Sieve® Majsx2

Operation:
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.

Operating Parameters
When using air jet sieving to determine particle size, there are four key operating parameters that need to be consistent to produce repeatable and reliable results.

  • Sieving Time – The sieving time plays a big 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 sieving time cycle of 2 minutes. Two minutes provides ample time for the particles of the entire sample to have an opportunity to pass through the sieve screen or be retained.
  • Sieving Vacuum Pressure – Hosokawa recommends a sieving pressure between 8-16 inches of water column during a sieve analysis. If the pressure is too low, the air velocity passing through the rotating wand may not 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.
  • Sample Volume – In most air jet sieve particle size analysis devices, a sample between 10 grams to 100 grams is recommended, depending on the density of the material being tested. Samples larger than 100 grams can blind the test sieve screen affecting the analysis results.
  • Test Sieve Screen Quality – The integrity of a test sieve screen is critical in any particle size analysis process. Hosokawa only provides test sieve screens that are 99% accurate. These high quality test sieve screens help assure accurate results. Test Sieve screens with any damage such as holes, tears, scratches, waves or other imperfections are not recommended. Sieve screens should be recertified as recommend by the manufacture on a routine basis.

APPLICATIONS & USES

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 MAJSx2 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 customer use it to determine the average particle size below a specified cut point; for example, D90 < 50 µm 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.

Particle Size Analyzer Systems

Basic 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.

  • Manually Operated Mikro Air Jet Sieve® model MAJSx2
  • Test Sieve Screens
  • Vacuum
  • Optional High Efficiency Cyclone

Advance 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.

  • Computer Assisted Mikro Air Jet Sieve® model MAJSx2
  • Test Sieve Screens
  • Balance
  • Vacuum
  • Optional High Efficiency Cyclone
