AMUT and AMUT Ecotech joint players

to supply recycling facilities

he Italian AMUT GROUP is globally considered as synony-

mous of flexibility and turn-key solutions mainly because

all of its divisions and companies collaborate together, sha-

ringknowledge and professional competences in three sectors:

extrusion, thermoforming and recycling.

As a result of this strategy, AMUT GROUP is always in position

to supply tailor-made equipment and installations to satisfy a

wide range of requirements.

AMUT Recycling Division, innovative manufacturer of plastics

washing plants, together with AMUT ECOTECH, high expert

of sorting and separation technology, represent an instru-

mental player in the waste processing systems field. AMUT

and AMUT ECOTECH become a sole reference to supply recy-

cling facilities.

Confirming this important strength, a recycling plant has been

recently supplied in England for a customer who preferred

AMUT over the others, not only for technological reasons but

also because he could find the advantage to buy a turn-key

mixed plastic sorting plant and HDPE washing plant by an uni-

que supplier.

In fact, AMUT plant is able to cover the comprehensive recy-

cling flow from mixed plastics sorting up to the delivery of fla-

kes. These flakes have a quality level suitable to be re-used in

further extru-

sion, injection or

thermoforming

process.

The plant re-

claims polyolefin

thermoplastics

scraps to be

transformed into

granules with an

output of 10

Tons/h.

The thermopla-

stic scraps come

from the urban

and industrial

separate collec-

tion and they

are previously

selected as:

- HDPE / PP con-

tainers and bottles for foods.

- HDPE / PP containers and bottles for detergents and chemi-

cals.

Plastics at inlet: HDPE and PP (75%), heavy plastics (25%).

AMUT designers usually work in collaboration with the tech-

nicians joining their efforts to develop performing machines

and proper structure in terms of optimisation of the overall di-

mensions and of an easy handling to facilitate the mainten-

ance interventions.

AMUT ECOTECH - PRF

The plant is fed by mixed plastics materials packed into bales,

loaded by a forklift on the extracting chain conveyor installed

in a pit, weighing system equipped with, and then conveyed

to the “bales breaker machine”, properly designed and ma-

nufactured to break up bales mainly composed by plastic ma-

terials. This machine doesn’t shred material but gets back bulk

material in order to feed the recovery plant in a constant and

regular way.

Breaking up of the bales is assured by the circular motion of a

drum equipped with fix teeth. The rotor’s sharp tools enter the

bales separating in this way all materials that fall in the below

conveyor belt, conveying materials to the pre-sorting picking

cabin where pickers take way bulky materials, mainly repre-

sented by cardboard and film, from the stream. After this first

selection, by a feeding conveyor, the material flow is conveyed

in the rotary trommel, where the separation depends on size.

Three different streams are possible.

1. Material having size smaller than 30 mm falls on a conveyor

tants, is filtered and then used again for the process.

After this strong washing action, the rinsing cycle starts into

two proper troughs in series where there is also the separa-

tion of light pollutants (paper, non-polyolefin thermoplastics,

etc.). The material is introduced in the bottom of the rinsing

troughs in order to improve their efficiency.

The light pollutants are so decanted, while the polyolefin float.

Also these rinsing troughs are equipped with an automatic ex-

tractor of decanted material and heavy plastics. This mixed pla-

stics are dried by a centrifuge and stored in big bags.

The Washing Section operates in a fully automatic cycle, con-

trolled by a centralized board.

The equipment has been designed to assure both separation

and complete cleaning of thermoplastic material from all the

pollutants having specific weight higher than the thermopla-

stics one.

Possible residuals of pollutants, not extracted in the Washing

Section, will be filtered during the process in the Granulation

Section.

Once all materials are selected, they are stored into the sto-

ring unit by type, ready to be discharged in the collecting con-

veyors to be then sent to the baling press, for the final

packaging of bales.

belt, where is conveyed, jointly to the one fine coming from

the ballistic separators, to the residue storing unit.

2. Material having size between 30 and 260 mm, is conveyed

to the ballistic separator where the rolling shape and the hard

materials are separated from the light and flat ones by the

paddles sussultory movement. Furthermore, thanks to the

grids installed on the paddles, fine material not yet separated

by the rotary trommel, is evacuated and conveyed to the spe-

cial storing unit. Flat and light material are conveyed upward

by a conveyor.

“Rolling shape and hard materials” sorted by the action of the

ballistic separator, are conveyed to the plastics automatic se-

lection line where plastic material will be automatically selec-

ted by optical readers.

3. Oversize materials stream, having size bigger than 260 mm

is conveyed to the bulky materials picking line, where, different

types of materials, mainly film and good plastics to be sent to

the automatic line are manually selected and discharged in

chutes.

In order to get the higher quality of materials, after the NIR

optical reader they are provided QC (quality control) stations,

where pickers recycle errors, conveyed at the beginning of the

automatic line to get more efficient the line. A manual chek-

king line is also provided.

Before entering the automatic line, “rolling shape and hard

material” (plastic materials stream) stream passes through a

de-metallization line, consisting of an over band magnetic se-

parator used for ferrous materials and, an Eddy Current Sy-

stem (based on the Foucaults currents principle), used for

no-ferrous metals. Ferrous and no-ferrous materials selected

in the de-metallization line, are weighed by weighing system

hopper and then discharged into hook-lift containers.

AMUT - WASHING SYSTEM

The main washing action on the product is made by the Fric-

tion Washer, thanks to the intensive friction of the rotary

paddles among the flakes. Even if it is continuously fed, the

friction washer allows an adjustment of the stay time of the

material.

A characteristic of this unit is its noiselessness, therefore a

soundproof box is not required.

The water, coming from the friction washer with paper pollu-
