Sieving for perfect

quality control
 Particle Sizing

The widest range of sieving

equipment in the world!
RETSCH’s line of sieving machines not only covers a wide measuring range. Thanks to various
sieving motions and sieve sizes it is possible to select the ideal instrument for practically any
bulk material. The instruments produce exact and reproducible results and comply with the
requirements for the test materials monitoring according to DIN EN ISO 9000 ff.

The RETSCH AS 400 control is used for the sieving of dry

goods with test sieves of a diameter up to 400 mm. The
horizontal circular sieving motion is preferably used for
long or fibrous, needle-shaped flat materials. The hori-
zontal orientation of the particles allows for better repro-
ducibility of the sieving results. Fine and coarse-grained
goods as found in the areas of milling, brewing,
chemical industry, quarries, soil testing, woodwork-
ing and plastics industry, can be exactly separated with
the AS 400 control. For the testing of plastics (grainy
moulding materials), the DIN 53 477 even requires the
circular sieving motion.

Mechanizing hand sieving

The RETSCH AS 200 tap is suitable for dry sieving with

test sieves of 200 mm or 8" diameter. The combination
of horizontal, circular sieving motions with vertical taps
reproduces the principle of hand sieving. The uniform
mechanical action ensures reliable and reproducible
measurement results.

This special type of sieving motion used by the AS 200 tap

is specified in various standards for particle size analysis
of materials such as activated carbon, diamonds, spices,
metal powders, abrasives or cement.

 TEST SIEVES

RETSCH Test Sieves

With Ø of 200 / 203 mm (8")

The demands made of particle size analysis are constantly increasing. This is
also reflected in the requirements made in the standard ISO 3310. RETSCH
has developed a unique manufacturing process that guarantees a previously
unattained quality and consistency in sieve production. In addition, a logistic
manufacturing system makes it possible to record each and every material
used in the process.

The sieves are fully compatible with RETSCH’s existing products and can
be combined with other sieves without any problems. Each sieve
that leaves our company includes a test report or, at your request,
a special inspection certificate in conformity with ISO 3310-1.
RETSCH's calibration certificates ensure a higher statistical
reliability and document our continual quest for perfection.

RETSCH’s sieves are available in the four most widely used sizes:
200 x 50 mm · 200 x 25 mm
203 x 50 mm (8"x 2") · 203 x 25 mm (8"x 1").

Production process: 1. 2. 3. 4.
1. Data entry
2. Welding
3. Lasering
4. 100% optical inspection

Seven Unique Benefits

Our unique manufacturing process ensures an 1. One piece construction and fabric-transition
optimum design for each sieve. Experience yourself without any grooves to prevent cross conta­
the increased quality of your analyses as well as mination (no solder*, no epoxy, no residues,
improved handling and service life of the sieves. etc.)

2. A high degree of corrosion resistance and

ease of cleaning due to high-alloy stainless
steel (specification: 316)

3. 15% lighter than traditional sieves while at

the same time increasing the free sieve area

4. Previously unattained product quality due to

fully automatic production and extensive
optical inspection with optimum design

5. Innovative resistance welding technology

guarantees permanently tight sieve fabric

6. Maximum stability and optimum

sealing when used in sieve stacks

7. Clear and precise labeling of the sieves

with full traceability based on individualized
laser engraving

 EVALUATION SOFTWARE

Control, evaluation, documentation

with EasySieve®

Simple, fast, and reliable

EasySieve®, the software for particle size analyses,

ex­ceeds manual evaluation in many aspects. The
software is able to automatically control the necessary
measurement and weighing procedures – from the
registration of the weight of the sieve to the eva­
luation of the data.

Due to the logical design of the software the user

can easily get started with the program and is lead
through the process step by step. More­over, the
abundance of evaluation possi­bilities allows for
absolute flexibility with regard to adjustment to
individual tasks.
