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.


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.


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,


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,


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.
