Automated line for sorting PET bottles, Al and Fe cans

This automatic sorting line is designed for a capacity of 4,500 kg/hour and is used to treat waste material kept in “yellow bins”, i.e. PET bottles, aluminum and iron cans.

Firstly, material bales are unpacked and the material passes through a trommel screen.

Afterwards, ferrous cans are separated by a pair of very strong DND-AC TIGER overband magnets.

The reliable separation of aluminum cans is performed using the ECS-C RAM eddy current separator with a concentric rare earth rotor. Before being processed by the ECS separator, the material is spread on the conveyor belt by a vibrating feeder (the uniform material distribution is a prerequisite for the proper functioning of the ECS separator).

Finally, the PET bottles are sorted by color using a NIR / VIS spectrophotometer.

The individual types of the sorted materials are pressed.

The functionality of the entire sorting line and its parts is monitored by a camera system. The advantage of such a system is the possibility of remote access to individual control elements of the sorting line.

• The separation line capacity: 4.5 t/h + 3.5 t/h (Al packaging)
• Guaranteed separation

Output

The treated waste is sorted into the following material fractions:

• 3D PET bottles
• Aluminum cans
• Iron cans

The sorting line consists of the following equipment:

1. Conveying system
2. ECS-C 1000 RAM eddy current separator with centrically mounted rotor - for conveyor belts of 1,000 mm width
3. NIR / VIS spectrophotometer
4. Trommel screen
5. Accumulation storage boxes
6. Automatic baler
7. Crushers
8. Steel construction
9. Complex control system with PLC outputs directly on the sorting line
10. Remote access
11. Camera surveillance
