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.

HMPS accepts no responsibility for damage to the instrument resulting
from the cleaning process and/or misuse of cleaning solutions.

Section 11: Optimizing Sieving Times

 The Mikro Air Jet Sieve® process can be optimized to save time when performing an analysis.
 To achieve the optimum time, select the finest Test Sieve Screen used during the analysis.

 Place the same amount of sample, typically used, on the Test Sieve Screen and identify

the total weight.

 Manually record this weight.
 Program (10) ten seconds into the “Sieving Time” (MAJSx2-a) or the “Time Remaining”

(MAJSx2-b) and run the unit until it shuts off.

 Brush any dust that accumulated on the Test Sieve Cover back into the Test Sieve Screen

and weigh the Test Sieve Screen with the retained sample.

 Manually record this weight and continue to repeat the ten-second increments, recording

the weights, until you find you have three runs without any weight change.

 Once the fine particles have been removed and the weight no longer reduces, the

optimum time has been achieved.

 The optimum time can then be set at twenty seconds shorter than the total length of your

test protocol.

 This optimum time can also be used on both fine as well as coarse opening Test Sieves

Screens.

Section 12: Maintenance

Section 12-1: Disassembly and Cleaning

 The information contained here-in is intended to be a guide ONLY. Frequency and extent

of cleaning depends on the user’s corporate policy, regularity of use, material and

environment.

 Remove as much dry powder using a vacuum prior to starting the cleaning process.
 Use the MAJSx2 “ON/OFF” power switch to the “Off” position, then un-plug the Jet Sieve

from the power source and remove the power cable from the body.

 Using a sponge, cloth, etc., lightly wash the pan area of the MAJSx2. Care should be used

NOT to oversaturate the area such that liquid collects in the pan or discharge duct. An
excessive amount of liquid will damage internal electronic and mechanical components. If
a scouring pad or hard bristle brush, or similar are used, surface damage to the MAJSx2
pan or discharge area will occur. As a result CAUTION must be used during cleaning.

 Recommended Air Jet Sieve Housing cleaning can be performed by using either a dry

vacuum and or with a damp towel. In the event the damp towel method is used use a mild
non-corrosive/non-abrasive solution. Additionally when selecting a solution care should be
taken to prevent a reaction with any remaining powder residue.

 The exterior of the MAJSx2 is to be wiped down using either the dry or damp cloth method.

Under NO circumstance is the unit to be submerged or saturated with liquid.

 In the event the damp cloth method is used, the Air Jet Sieve should be permitted to dry

thoroughly prior to resuming use of the instrument.

 Under NO circumstances is the MAJSx2 to be subjected to steam sterilization.
 ONLY if authorized, remove the (4) mounting feet and the bottom plate. Inspect the

vacuum pressure gauge filter, should there be an excess of collected powder clean the
filter using compressed air and/or replace the filter.

OPERATING AND MAINTENANCE MANUAL

Mikro Air Jet Sieve®

HMPS accepts no responsibility for damage to Test Sieve Screens resulting from
misapplication, misuse and/or overheating during drying.

Section 12-2: Cleaning of Test Sieve Screens

 Test Sieve Screens must be cleaned periodically, especially those with fine openings.
 The frequency of cleaning depends on the characteristics of the powder and the number of

times the Test Sieve Screens are used.

 After a period of time, particles can wedge themselves in the sieve cloth opening eventually

blinding a portion of the Test Sieve Screen area.

 Once a week or more often if necessary, the Test Sieve Screens should be placed in an

ultrasonic bath, for NO Longer than 1½ minutes, with a mild detergent water mixture (1 part
detergent to 10 parts water).

 The Test Sieve Screen should be carefully (without contacting the sieve cloth) blown free of

excess water using compressed air, remove the O-ring then placed in an oven with a
temperature of 80°F to 100°F or allowed to fully air dry overnight.

 In some cases traces of water may still be present on the Test Sieve Screen.
 Place the Test Sieve Screen on the instrument and run the instrument without material

permitting the vacuum system air to remove any of the remaining liquid traces.

 Should there be an excessive amount of liquid present DO NOT use the Test Sieve Screen.
 DO NOT leave the Test Sieve Screens in water/cleaning solution for long periods of time.
 The adhesive over time will degrade when subjected to long periods of liquid submersion.
 The Hosokawa Micron Test Sieve Screens are autoclavable and can be subjected to High

temperatures (240°C) without damage to the frame and/or cloth.

 As a result placing them into an oven with the temperature between 80°F and 100°F will have

no effect on the adhesive.

 DO NOT subject soldered Test Sieve Screens to temperatures above 150°F. Should this

occur the solder may soften resulting in the loosening of the sieve cloth, ultimately
permanently damaging the Test Sieve Screen.

 The Black O-ring should be removed from the sieve frame for either hand or ultrasonic bath

cleaning with either isopropyl alcohol or a mild soap solution.

 When the ultrasonic bath method is used the test sieve gasket should NOT be submersed in

the mild soap solution.

 Any excess liquid should be removed from the O-ring by using a lint free cloth and it is

recommended that the O-ring be air dried overnight.

 In the event Isopropyl alcohol is used as the cleaning agent the Isopropyl alcohol should be

applied by means of a spray and immediately removed thoroughly using a lint free cloth and
/or compressed oil free air, then permitted to further air dry.

 The test sieve O-ring should NOT be placed in a high temperature oven for the purpose of

accelerating the drying process.

 The test sieve O-ring should NOT be subjected to heat or liquid or air greater than 100°F

Hygroscopic

 Use conditioned air
 Dry the sample before and after analysis
 Shorten sieving time

Electrostatic

 In some cases it is preferred to mix an anti-static agent with the sample.
 HMPS suggests adding approximately 2% (sample weight) of “High Purity

Silicon Dioxide”, which will adhere to the surface of the larger particles

and act as a barrier thus reducing particle to particle cohesion which
ultimately affects the static charge on the sample.

 In addition the use of a light coating of anti-static spray on the Test Sieve

Polycarbonate Cover and the Test Sieve frame will reduce the
electrostatic effect on these parts.

 Caution should be taken to NOT get the antistatic spray on the screen

cloth.

Sticky

 Difficulties may occur when attempting to sieve extremely fine or fatty

materials.

 The addition of “Highly Dispersed Silica” has shown to reduce and/or

eliminate these difficulties.
