Aqua vibrating separators
patented by ThyssenKrupp
Frdertechnik are used in the
sands and gravel industry as
well as in the recycling
industry for an efficient and
economic wet processing of
sand, gravel and other mixed
materials.
Aqua vibrating separators
remove organic impurities
capable of swelling andlow-gravity materials such as
wood, coal and plastics from
feed materials like sand and
gravel. Furthermore, excessive
fine sands are separated when
high-grade sands are
produced.
Thus, the feed material is not
only cleaned, but also classi-
fied.
Aqua vibrating separators
type ASS are used for sand
processing (Fig. 1), while the
ASK type is used for the
processing of granular feed
material like gravel,
for example (Fig. 2).
Important advantages of aqua
vibrating separators compared
to other systems:
Owing to the combination of
several processing steps in
one machine investment
and operating costs of a
processing plant are
considerably reduced.
The use of aqua vibrating
separators guarantees high
quality of the final product at
low water consumption.
Easy, quick and reliable
adaptation of the machines
to different applications.

While the ASS type isequipped with a dewatering
section, the ASK type is
provided with a classifier,
both arranged before the
discharge area.
The particularly efficient cleaning
and classification of the feed
material by aqua vibrating
separators is based on the
combination of differently acting
processes in one machine,
superposed by a vibrating
motion (Fig. 4).
The impurified sand fed to the
aqua vibrating separator
type ASS at a normal grain size
of 0- 2 mm is homogenized in
the prethickener (Fig. 5) by
adding water, thickened and
then fed to the area of upward
current water.
The grade of homogenization
can be optimised by the fresh
water quantity added and by
means of adjustable discharge
nozzles at the prethickener
discharge. The excess water is
discharged via the overflow of
the prethickener with sludge,
fine sand and low-gravity
materials.
The ASK type receives coarse-
grained materials directly from a
chute.
From the prethickener resp. the
chute the feed material enters
the troughed area of upward
current water (Fig. 7 and 8),
sloping upward in the direction
of transport of the material and
being equipped with teeter
plates. These teeter plates and
the vibrations of the machine
transform the feed material into
a dense medium, whose density
can be varied by adjusting the
upward current water quantity
and -distribution (Fig. 6).

In this jigging bed dense flow
separation and sedimentation
take place, superposed by
cross-current separation at the
jigging bed surface, which is
generated by the water flowing
off over the rear wall against
the direction of transport and
the countercurrent nozzles
(Fig. 9). Thus, the feed
material is cleaned and
low-gravity materials,
impurities and fine sand aredischarged over the rear wall.
The height of the rear wall is
adjustable, i.e. the height of
the jigging bed can be
controlled and the discharge of
fine sand can be varied.
The area of upward current
water is followed by a
relaxation zone (Fig. 9, 10),
also sloping upward in the
direction of transport.
This is where the counter-current nozzles are mounted
above the jigging bed and the
purified feed material is
settled.
Further low-gravity materials
and impurities are discharged
with the help of a surface
current which flows towards
the rear wall and which is
generated by the counter-
current nozzles.
The relaxation zone is followed
by a dewatering section
(Fig. 10) resp. a classifiying
section (Fig. 11).
In this area the upward slope
of the machine decreases
considerably in the direction of
transport (Fig. 4).
In the dewatering zone the
moisture content of the
cleaned and classified feed
material is reduced to a
specified value.The dewatering section is
interrupted by baffle plates.
In the classifying section the
feed material is separated into
different fractions depending
on the mesh width and the
number of screen decks.
The cleaned and classified
finished product is discharged
at the end of the dewatering
resp. classifying section.
The vibration drive (Fig. 6)
is a forced-synchronization
twin-shaft unbalance vibrator
like that used in screen
systems. Both linear and
elliptical or in case of
masses rotating in the same
direction circular vibrations
can be generated.
For influencing the process of
feed material cleaning and
classifying, the followingcontrol options are available:
Regulation of the dischargerate at the prethickener.
Adjustment of the overflowheight at the rear wall.
Regulation of the volumeflow and distribution of
upward current water in the
upward current water zone.
Variation of the amplitude,vibration angle, acceleration
and vibration mode of theaqua vibrating separator.

We work closely with different
institutes and universities in
order to optimise existing resp.
develop new aids for the
design of processing plants
and machines.
When a new project is started
field analyses and tests are
carried out. In addition to the
use of existing fundamental
knowledge these analyses and
tests are indispensable for thedevelopment of appropriate
solutions to a given problem.
Furthermore,
ThyssenKrupp Frdertechnik
uses up-to-date methods to
ensure that the best possible
solution to the problem is
found.
This comprises the finite ele-
ment analysis (Fig.13) and a
specially developed point load
testing instrument and
-method for the determination
of strength properties of rocks.
Physical properties of materials
to be processed by means of
aqua vibrating separators as
well as processing aims vary
according to the deposit.
Moreover, the feed material
properties may considerably
change with the advancing
face.
In order to be able to analyse
the cleaning and classification
process under individual,
realistic conditions already be-
fore an investment in an aqua
vibrating separator is made,
ThyssenKrupp Frdertechnik
developed a new test
apparatus (Fig. 14).
Our services include project
research, damage analyses,
planning and modification
aimed at a modernization and
an increase of the output of
machines and plants in
conjunction with a worldwide
after-sales service which also
covers the equipment of other
manufacturers.
