OPERATING AND MAINTENANCE MANUAL

Mikro Air Jet Sieve®

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.

CRITICAL OPERATION INFORMATION:

 The MAJSx2 was 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 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 MAJSx2 during operation, should read

between 8 and 16 inches water column. Refer to page 49 for vacuum gauge verification procedures.

 Utilizing the standard MAJSx2 arrangement, 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.

The back of the MAJSx2 is to be positioned no less than a minimum of six
(6) inches from a wall or a solid obstruction to enable the operator easy

access to the “Power” switch and the Circuit protector.

Section 5: Unpacking and Installation

 Unpack and remove the MAJSx2 from the shipping box. Confirm receipt of all required

components as detailed in the “What’s in the Box” section.

 Place the accessories (sieve cover, tapping hammer, sieve brush, power cord and, depending

upon the model, the USB “Flash Drive” and CAT 5 cable) aside for the moment.

 Locate the MAJSx2 on a level, firm horizontal laboratory bench/table capable of sustaining

vibration and positioned for easy operator access.

 Refer to General Arrangement Drawing below for dimensions. The MAJSx2 weighs approximately

26 Lbs. (11.8 kg). All necessary CAUTIONS are to be used when lifting the instrument.

 Prior to attaching the power cord to the MAJSx2, confirm that a 3-prong 90 to 240 volt, 50/60 hertz

grounded house outlet is within three (3) feet (36 inches) (1 meter) of the MAJSx2. The electrical
power outlet should have “Ground” (“Earth”) protection, and rated for a minimum of 15Amps@110
volt / 10Amps@230 volt, 60/50 Hertz.

 Confirm that the power switch, located on the back of the MAJSx

the power cord into the receptacle located on the back (labeled “A/C IN”) of the MAJSx. Insert the
opposite end of the power cord into the house power receptacle.

 MAJSx2 ADVANCED OPERATION: Insert the USB “Flash Drive” into one of the USB ports

located on the back (labeled “USB”) of the MAJSx2 for additional storage capacity. Note: The

MAJSx2 will recognizes each USB “Flash Drive” by clicking on the ICON located in the upper
left corner of the display.

 Open/Unpack the vacuum and confirm receipt of all the required components (Vacuum Main Body,

One (1) Primary collection paper bag, and one (1) two (2) meter length (minimum) of hose with
connection cuffs, Power Cord, and Operation Manual). Additionally, confirm that the filters are

properly installed in accordance with the manufacturer’s instruction manual. Prior to closing the

vacuum, familiarization with the inside of the vacuum, especially the filter installation, is
recommended. Where ever possible, locate the vacuum, depending upon the vacuum physical
size, beneath or alongside of the lab bench/table. If mounted beneath the lab bench/table, to
eliminate the hose from being draped over the top of the bench/table, drill a 2.5 inch (63.5 mm)
diameter hole in the bench/table countertop. This size hole will provide ample clearance to pass
both the vacuum hose and vacuum power cord through the countertop making for a cleaner
installation.

 After locating the vacuum under the bench/table or in another convenient location, plug the

vacuum power cord connector into the MAJSx2 female vacuum power receptacle, (rated for
15Amp@110 volt / 10A@230 volt) located on the back of the MAJSx2. NOTE: the vacuum
operating voltage MUST be the same as the voltage that is supplied to the MAJSx2. In order to
achieve reproducible analysis results using the MAJSx2, the vacuum MUST always be plugged
into the MAJSx2 power outlet IEC 60320 C-13 receptacle (or adapter), (rated for 15Amp@110 volt
/ 10Amp@230 volt) located on the back of the MAJSx2. The vacuum’s power switch MUST
always be in the “ON” position.

 Using the supplied vacuum hose, connect the vacuum hose to the MAJSx2 vacuum port located on

the back of the MAJSx2, labeled “Vacuum Inlet”.

cable will be required for connection to the MAJSx2. When using a direct connected printer, locate
the printer, depending upon its physical size, as close as possible to the MAJSx2. After positioning
the printer, plug the printer power cord into an independent wall socket. Next make certain to
connect the printer USB cable to one of the USB ports located on the back of the MAJSx2. After
connecting the components, follow the manufacturer’s instructions to complete the installation.
