Section 1: Process Description
The Mikro Air Jet Sieve®–Model X2(MAJSx2) is easy to operate and quickly determines particle size with
a short series of sieve test 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 and confirmation of final product
specifications.
While under negative pressure sample particles are dispersed and de-agglomerated by means of a
positive airflow introduced upward through the rotating slit wand. Those particles small enough to pass
through a defined Test Sieve opening are carried in the airflow to the vacuum collector.
Precise particle size ranging from 20 to 4,750 μm can quickly be determined. This unique rotating wand
method also eliminates the need for tapping or brushing and increases reproducibility with controlled
measurements of pressure drop and duration. Overall the system is designed to operate cleaner, quieter
and requires less space than other types of similar analytical equipment.
The most important variables to insure a repeatable analysis using the Mikro Air Jet Sieve®are as follows:
The Sample Volume.
The Vacuum Pressure.
The Sieving Time.
The Test Sieve Screen Integrity.

Section 2: Principles of Operation
The Mikro Air Jet Sieve®- Model x2(MAJSx2) is a highly accurate and reliable particle size analyzer
designed to determine the particle size distribution of dry powders ranging from 20 to 4,750 micron. The
short sieving times at each sieve cut point are obtained by a reverse air current jetting out of a rotating air
wand beneath the Test Sieve Screens. This jetting air action disperses and distributes the analysis
material across the surface of the Test Sieve Screen. A Vacuum Fines Collector produces the required
airflow jetting action. The same airflow carries the fines fraction that passes through the Test Sieve
Screen, according to the principle of aerodynamic sifting. The fines fraction is then collected in either a
High Efficiency Cyclone or the Vacuum Fines Collector. A step-by-step description of this sieving action of
the Mikro Air Jet Sieve®as shown on Air Flow Diagram Sketch No.: 011414.1, on page 7 of 56 is as
follows:
Air enters through the Air Inlet opening located on the back of the MAJSx2.
Air continues through the duct to the hollow rotation wand.
Air exits the special shaped slot in the top of the rotating wand with sufficient velocity to pass through
the Test Sieve Screen.
The wand is propelled by the electric motor, thereby sweeping the complete diameter of the sieving
area.
The jet of air distributes, de-blinds, (dislodges) and possibly de-agglomerates the powder analysis
sample residing on the top surface of the Test Sieve Screen.
Those particles fine enough to pass through the Test Sieve Screen are carried away in the air stream
and collected in the vacuum and/or cyclone.
Air and fine particles enter the primary discharge duct and exit the MAJSx2.
The vacuum pressure is set by the operator on the “Testing” screen (while in the advance mode) or
“Sieving” screen (while in the basic mode) and is automatically adjusted internally by a rotating valve
located between the “Air Inlet” and “Vacuum” air ducts.
The recommended vacuum pressure range, displayed on the “Testing” screen (while in the advance
mode) or “Sieving” screen (while in the basic mode) of the MAJSx2during operation, should read
between 8 and 16 inches water column. Refer to page 49 for vacuum gauge verification procedures.
Utilizing the standard MAJSx2arrangement, the fine dust particles and air exit the main unit and travel
through the vacuum hose to the vacuum collection canister.
If an optional cyclone is attached the dust-laden air is redirected to the cyclone and based upon the
efficiency of the cyclone the coarse particles are collected in the cyclone container and the ultra-fines
are carried in the air stream to the vacuum collection canister.
CRITICAL OPERATION INFORMATION:
The MAJSx2was designed for use with the Hosokawa Micron Test Sieve Screens. While certain
manufactures screens can and do fit the instrument, Hosokawa Micron Powder Systems cannot
guarantee operational results and is not responsible should any damage occur.
Hosokawa Micron 200mm diameter Test Sieve Screens are supplied with a Blue Test Sieve Gasket and a
Black O-Ring. Remove and Discard the Blue Test Sieve Gasket. ONLY the Black O-Ring is to be used
on the Test Sieve Screen for proper vacuum seal.

Section 3-1: Precautions
The precautions shown below are for safe operation of the MAJSx2.
In this instruction manual, in order to use the MAJSx2safely, the following indications and symbols are
used to identify precautions.
CAUTION:
Indicates that handling the machine improperly could result in severe personal injury, death or
serious property damage.
Locate the MAJSx2in an area where the electrical components will not be exposed to water.
Locate the MAJSx2in a place where it will not be adversely affected by high temperature, high
humidity or excessive dust. Asafe operating temperature range is -10˚C ~ 60˚C (14˚F ~ 140˚F)
Relative humidity should not exceed 90% non-condensing.
Do not subject the MAJSx2to strong shock or vibration. Doing so can and will result in failure of
the MAJSx2.
As specified by the Material Safety Data Sheet (MSDS) of the powder being analyzed, use
proper personal protection and/or a suitable respirator in accordance with plant policy, OSHA or
local regulations

WARNING:
The instrument is to be properly grounded (earthed); not doing so may result in an electric
shock.
While the machine is energized and running, never open the Access Covers. Doing so may
cause injury.
Before performing maintenance, inspection, etc., turn OFF the power to the main body and
