Air Jet Sieving Maschine
TYP 500 LS |
Air Jet Sieving Maschine
LS
Dry sieving + classifying
+ screening
 |
For sieving very difficult and wearing products with sieve mesh widths
approx.
25 – 500
µm.
|
|
|
Control screening resp. protective screening.
|
|
|
Sieving maschine with oszillating slotted nozzles below the screen.
|
|
|
With vibration transport of sieving product.
|
|
|
Pneumatic screen
tensioning device. |
|
|
| The Alpine air jet sieves LS were developed
for sieving powdery materials at extremely fine sieve mesh widths.
And where conventional sieving system fail, for example when
sieving materials with critical properties, the Alpine systems
have proved to be absolutely ideal. |
|
|
Typical areas of
application |
|
|
Abrasives: fractionation of granulations in the range of
approx. 25 – 500 µm. Protective screening as a topsize control of final abrasive
fractions. |
|
|
Metal
powders; metallic compounds such as copper, cobalt, nickel, and
magnesium powders, gold bronze etc. |
|
|
High-tech ceramics powders |
|
|
Electrostatically charged materials, e.g. plastic powders such as PVC,
Polystyrol, Polyethylene, Polypropylene |
|
|
Protective screening when producing powder coatings. |
|
|
Industrial chemicals such as silicic acids, etc. |
|
|
Materials which tends to agglomerate and form deposits, e.g. iriodin,
metal stearates, wheat bran etc.

Depending
on the product, the Multiplex Zig-Zag Classifier can separate in the range of
0.1 mm to 10 mm. These classifiers are ideal for separation of materials which
are difficult to sieve or cannot be sieved at all, and separation of pieces
having approximately the same size, but different specific gravity.
 |
Multiplex
classifiers are virtually maintenance and wear-free and are
insensitive to changes in the composition of the feed material.

Ventoplex
air classifiers separate in the fine to medium-fine particle size range from
approximately 45 to 300 µm. The feed material is introduced without air and the
fines and coarse material are also separated without air, meaning that a
separate, external dust collector and exhauster is not necessary. Whether for
normal products, abrasive ones, or for special applications such as explosive
dusts, the Ventoplex classifiers deliver excellent product quality and have been
proven to be "work horses" under even the most harsh conditions.

| The
Turboplex is ideal for ultra fine classification of superfine powders. The
patented multi-wheel design offers the same sharp top cut as a single wheel ATP
but can achieve up to 6 times the capacity of a single-wheel classifier. The
classification of the product is a function of the peripheral speed or the speed
of the classifying wheel and the radial speed of the air flowing through the
classifying wheel. The material's fineness can be controlled by altering the
speed of the classifier wheel. Rejected material is discharged at the bottom
of the classifier. |
 |
The ATP can produce fines in the range of d97=4 microns or finer. The monobloc
classifier wheels are available in SiC or Alumina. In this wear-resistant
construction they can operate at the same speed as the steel classifier and thus
achieve the same particle size cut. The monobloc design is ideal for
processing abrasive materials such as feldspar and quartz.
With the newly developed NG-wheel (New
Generation), the pressure drop across the classifier wheel could be
significantly (up to 50%) reduced. This means lower capital costs as well as
lower operational costs.

Stratoplex
air classifiers are newly developed high-efficiency air classifiers for the fine
to medium separation range with a d97 of approximately 10-200 µm.
Even at high feed rates, the quality of classification is maintained. With a
pressure drop of only approximately 30-40 inches water column for the entire
classifying system, low-energy operations are guaranteed. |
 |
The Stratoplex is a
compact and modular system and permits not only top performance but also a
trouble-free, space saving system installation. Many sizes are available
with capacities of up to 100 tons/hr feed.

A
totally new design for ultrafine powder classification in the 1.5 to 30 micron
size range, the TSP Classifier is ideally suited for toner powder coatings
applications. When manufacturing fine powders, the very nature of the feed
material makes it unavoidable that a certain amount of ultra fine dust finds its
way into the product. The TSP classifier was developed especially for the task
of dedusting these fine powders. It features a targeted material flow which
produces clean coarse product without undesirable ultrafine portion, providing a
high precision of cut with maximum loose yield.

| The
new TTSP Classifier is ideal for the toner industry, where sharp separation of
fines and a high coarse product yield result in improved product quality and
higher profits. Coarse yield improvements of 5% over the proven TSP Classifier
and over 10% over other classifier designs have been realized. Product changes
with the TTSP Classifier are made simple. The classifier is designed with a
hydraulic opening split body. All material contact parts are vertically
removable, leaving the interior accessible for cleaning. |

| With
the requirement for high product quality and maximizing yields for powdered
material production, in-line classification is a definite advantage. Hosokawa’s
new MikroClassifier CC is an in-line classifier that can handle a wide range of
materials in many size ranges making cut points between 5 micron and 100 micron
possible. |
 |
The MikroClassifier CC’s unique internal dispersion of material
allows for sharp particle distributions while maintaining high throughput. Its
compact design allows for complete access to the interior to facilitate cleaning
and product changeover.

The
Hydroplex wet classifier employs a rotating deflector wheel and the counter flow
principle to separate the product into a coarse and a fine fraction. The
operating range is for feed particle sizes below 200 µm, whereby cut points down
to finenesses of approximately 4 µm can be achieved. The Hydroplex wet
classifier design features a hydraulic lifting device for quick and easy machine
dismantling, a simple and compact design, and easy cleaning and
maintenance. Several machine sizes with deflector wheel diameters of between 63 and 400 mm
are available.
