lump & neckdown detector an essential

tool for faultless quality control.

This detector is, in addition to other ver-

sions, also available as a stand alone de-

vice.

A unique measuring principle and com-

plex optics solution ensure immunity to

stray and intense light whilst providing

the highest detection accuracy and iden-

tification of lumps and neckdowns in the

micrometer range.

For continuous quality control, lump &

neckdown detectors are as important as

diameter gauges and spark testers.

The line of KW 13TRIO and KW 33TRIO

detectors capture with the highest accu-

racy, reliability and velocity even the

smallest lumps and neck downs in wires,

conductors, optical fibres, cables, tubes

and hoses.

Thanks to the separate operating and

display unit BAE 2 KW, the KW 13TRIO

and KW 33TRIO can be fully operated

and configured at the device. This unit

features an illuminated graphic module

to display values and messages, red, yel-

low and green tolerance indicators for

signalling operating states, a keyboard

with function keys and a numeric keypad

for manual instrument setting. The BAE

2 KW can be fixed at the operator sta-

tion by means of the included wall

mounting bracket (swivelling) or on the

table.

Thanks to its very compact design, the

KW 13TRIO and KW 33TRIO fault detec-

tors can easily be integrated in any extru-

sion line or rewinding process. The mea-

suring field is dimensioned in such a way

that during the start-up, even extremely

big lumps pass smoothly through. Its

open design enables quick and easy

threading of the product without stopp-

ing production.

A powerful micro processor as well as

full digital signal processing, makes this

Highlights

• Complex optics allows:

- Min. detectable fault height of

0.01 mm (at KW 13TRIO)

- Min. fault length of 0.2...0.3 mm

(at KW 13TRIO)

• Full digital signal processing DSP

• Very compact design

put of 2500 kg/h. The thermoplastic

scraps mainly consist of baled blown

films coming from postconsumer recy-

cled packaging. In order to increase the

flexibility of the plant, a group of convey-

or belts enables the two shredders to

feed alternately two buffers on the lines.

The decantation phase permits to sepa-

rate the heavy objects and contaminants

from the film whilst a pre-washing action

removes other pollutants and dirt. The

second high friction action is made dur-

ing the wet grinding.

two tenders issued by European leading

companies both involved in the waste ma-

nagement field. Each supply includes one

twin plant suitable for the reclaiming and

regeneration of thermoplastic polyolefin

scraps to be transformed into granules.

The water-saving concept of the AMUT

patented technologies are well known all

around the world because of the treated

water that can be re-used thanks to spe-

cial recirculation circuits. For the first pro-

ject, the two lines will process, working

in parallel, LDPE scraps with a total out-

chines perform an intensive and con-

tinuous washing and rinsing action. The

process washing water can be thermally

adjusted

and

conditioned

chemicals/detergents to increase the

cleaning efficacy.

The flakes are separated from water and

conveyed to the centrifuge machine for

the drying phase. A hot-air drier reduces

the humidity value of the flakes and

makes the material suitable for the ex-

trusion processes.

For the other project, AMUT will supply

twin lines for washing and pelletizing of
