Functional description

 

The input material to be sorted is fed to the feeding proportioner by means of a wheel loader.

Large materials (>500mm feed size) and solid disturbing components should be removed prior

to feeding.

Plastic or paper bags containing waste can be opened by the feeding proportioner.

The material exposed after the feeding proportioner is transported to the two-stage separator

using conveying engineering, where it is separated in three fractions.

From the fine fraction, all ferromagnetic elements are removed using a permanent magnet.

These elements are fed to a container on conveyor belts.

The remaining fine fraction flow is discharged in a silo. The material is removed by means of a

wheel loader and subjected to a further treatment or deposited on a disposal site.

The flat/light material which is discharged by the separator on the top side is transported via the

conveyor belts to the sorting cabin where it is fed to the manual sorting on two sorting

conveyors. During the manual sorting recyclable materials, such as foil, cardboard, paper, and

possibly textiles can be removed form the material flow. The removed recyclable materials are

discharged in a collection silo via discharge chutes. They are moved to a press conveyor by

means of a wheel loader and then transported to the bale press. The bale press presses the

material to marketable bales.

The material remaining on the sorting conveyor is discharged from the sorting cabin and fed to a

container loading unit via a conveyor system.

Such material is either deposited or incinerated.

From the rolling/heavy fraction, all ferromagnetic elements are removed using an overband

magnet. The removed recyclable material is added to the same container as the metals of the

fine fraction. After metal separation the material slow is led through an eddy-current separator.

The eddy-current separator separates aluminium components by rejecting such parts. The

aluminium is fed to a container via a conveyor belt. The resulting material flow liberated from FE

and NE is now fed to two optical detection devices. These devices use a near infrared

technology to detect various metals and separate them by means of an air blast. In the rolling

fraction, separation of plastics would be reasonable. For example, PET and PE. Discharge of

combinations such as PE combined with PP is also possible. Different options are available.

 

The discharged fractions are manually cleaned in a sorting cabin in order to ensure a

marketable quality. The residue of theses sorting conveyors is discharged in corresponding

silos. The discharge of the silos has been described above. The material not removed by the

optical detection device is fed to the remainder belt already described.

Subject to the customer requirements, integration of a manual sorting or an additional optical

detection device in this remainder belt of the rolling fraction would be possible, if required.
